Lights, Camera, Laser Imaging

Ariddle: How do you take a picture around a corner without moving the camera? Impossible, right? Apparently not.

Lights, Camera, Laser Imaging 1

New research from the Massachusetts Institute of Technology and UW-Madison proposes a design for a camera that can do exactly this. The device, dubbed CORNAR (corner sonar), bends logical thinking through its ingenious design. Assistant Professor Andreas Velten of UW-Madison has been working to perfect the device right here on campus.

Velten first started working on the CORNAR technology at MIT but brought the research to UW-Madison in order to continue his work with the device. Physically, the CORNAR camera is as big as a table, and cannot fit through a door; while cumbersome, the large size is necessary for the camera to contain all the hardware needed to accomplish its impressive task. The device works by mounting a regular camera on top of a platform, which has different types of hardware connecting to the camera and a computer.

A laser attached to the camera emits photons, or particles of light. Upon hitting a surface, the photons bounce around other surfaces. Some of these particles make their way back to the lens of the camera, where, using a method similar to sonar, the software analyzes the time lapse between the light particles colliding with the surface(s) and coming back to the camera lens.

This time-lapse information allows the device to map out the area around the corner and display it on the computer screen.The images that CORNAR produces are low quality but useful in many situations. For example, police can use this device to see if someone is around the corner or if an obstacle is in the way without risking harm to officers.

Further applications include rescue missions in which people are trapped under rocks, testing machines to see if all parts are functioning properly, and mapping of hazardous places like volcanoes from a distance.Currently, Velten and his team are simulating how CORNAR would map the layout of moon caves. Their research is evaluating whether a satellite would be able to capture images while constantly moving and how much time it would take to scan the moon.

From early test results, Velten and his team have successfully determined that the motion-capture imaging works; however, the duration to complete a scan could take days or weeks. While the camera itself can generate an image in a matter of seconds, the light particles can take hours to return to the lens. Further issues arise from the possibility of the lens detecting other light particles, which would cause the image to be compromised, another challenge they are working on.

Besides applying CORNAR to the mapping of the moon, Velten and his team are further developing the technology to enable the camera to see around two corners rather than one. The process is the same, but the algorithm needs to account for the extra time it takes for light particles to bounce back from even greater distances, lengthening the process. In situations where there is a long wait time, such as a hostage situation, this would be useful for the police to scout out the general layout, observe if someone is moving, and see where people are located in relation to the doors.

This technology could even help them map out a room where theres a possibility of a trap like a bomb or trip wires.So if you havent already guessed the answer to the riddle, it is CORNAR and its amazing light-bending technology. It might be some time before this technology will be available for the average person to use, but each day is taking these dedicated researchers one step closer to making this concept come to light RELATED QUESTION What are the best Christmas laser lights?

Things to Remember Before Buying Christmas Laser Lights Chassis Material Waterproofing Laser Colors Laser Patterns Remote Operation Indoor / Outdoor Chassis Material Is the laser projector made out of metal or plastic? It should go without saying that metal lasts longer than plastic. Depending on the type of weather that is frequented in your area, one or the other might suit you more appropriately.

In places with severe weather, metal would probably be the best choice; however, in places with very moderate weather, plastic will do just fine and probably save you a little money. Waterproofing Is the projector waterproof? Some projectors are waterproof while others arent.

If you plan on using one outside, youll definitely want to have that extra protection from the rain and snow. On the other hand, if you are only going to use one for inside purposes, you might not need it to be weather resistant. Laser Colors What colors will the projector display?

There are two standard color combinations that are found on most laser projectors. Usually, those designed solely for Christmas contain red and green lights. Others that are used for Christmas, as well as other holidays or parties, contain red, green, and blue (RGB).

Depending on whether you only want lights for Christmas or need a multipurpose unit, you might find one product more appealing than the other. Laser Patterns What kinds of patterns does the projector show? Patterns are at the core of what laser lights are all about.

Some projectors give you the option to select exactly which colors you want to display and how the colors move and morph. Others do not give you these options and have a set way that they operate. Youll have to decide whether you want to pay the price for more control over your patterns or settle for what is given to you.

Remote Operation Does it include a remote? Many, but not all, laser projectors come with a remote controller that allows you to control the projectors functions from a distance. Some controllers have a range of just a few meters while others can reach a very, very long distance.

And, again, some projectors dont come with a remote at all. If convenience is what you seek, this is a factor that will definitely play into your decision-making. Indoor / Outdoor Can I use it indoors or outdoors?

Laser projectors are usually made to be used indoors, outdoors, or both. You wouldnt want to buy an indoor laser projector and place it outside just to have it ruined by the weather. For example, those made solely for indoor use are usually not waterproof while those designed for the outdoors are; rain and snow would damage a unit only made for the indoors.

In addition, indoor projectors usually have a shorter projection range than outdoor ones. An indoor unit used outside might not turn out to be as bright as you would like. And, you might think that using an outdoor projector indoors would be super bright and suffer no problems; however, those designed only for the outdoors usually do not come with an optional indoor base to allow it to stand by itself on a flat surface.

These are some key details youll want to know. Personally, though, I prefer to use the slightly more traditional LED string lights for all my decorating needs. Ill go out of my way and buy new stuff such as laser lights from time to time, but Ill most likely be using string lights for every main decorating event.

Festivals with many holidays, such as Spring Festival, Tomb Sweeping Day, labor day and national day, are often the peak season and peak period of domestic tourism. With the rapid increase of traffic flow, the management pressure of parking lots in major tourist attractions increases. It is undoubtedly troublesome to find free parking spaces in parking lots. Now, intelligent parking lot guidance systems have been adopted in parking lots in many large scenic spots, This is a technology that uses video guidance technology combined with electronic map to provide vehicle search route. In the parking lot without guidance system in the past, tourists need to park at the entrance to pick up their cards, and then Park and swipe their cards when they leave the parking lot. It also needs manual charging, which greatly increases the time for vehicles to leave the parking lot. It is very easy to cause congestion during peak hours, which brings a bad experience to tourists. At present, all the new parking lots in the scenic area adopt intelligent parking lot license plate recognition system, which mainly uses the high-definition camera installed at the entrance to capture the vehicle license plate information, and then through the rapid calculation and processing of the system, you can enter the parking lot without parking. After entering the site, it is the time for the guidance system to play its role, It is mainly used to help car owners find the parking space in the parking lot and record the parking position data of car owners. When the car owners need to find the vehicle position when they return to the parking lot, they can conduct reverse car search with the help of the car search terminal in the parking lot, in which the car owners need to input the license plate number, The system can use the license plate number to give the area where the vehicle is located and the parking situation of the vehicle, and provide the electronic map of vehicle search and the optimal walking route, which is very humanized.

How to Make Full Use of Parking Lot Management System to Solve People's Parking Problems_ Taigewang
How to Make Full Use of Parking Lot Management System to Solve People's Parking Problems_ Taigewang
Speaking of people's parking pain points, in fact, they are not as serious as everyone said. As a manufacturer specializing in the production of intelligent parking lot management system, the parking pain points are nothing more than two points: one is the problem of waiting in line for vehicles in and out of the parking lot; The other is the charge. To solve these problems, what should the manufacturer of parking lot system do? For people's parking pain points, the first is the problem of waiting in line at the entrance and exit of the parking lot. Many car owners know that sometimes it takes us nearly an hour to get in and out of the parking lot, which will lead to traffic congestion in serious cases. In fact, I think the problem of queuing in and out of the parking lot is related to the number of parking lots. With the improvement of people's living standards, the number of cars is increasing, but the number of parking spaces in the parking lot is not increasing. Although many parking lots use the license plate recognition parking lot system, this intelligent equipment alone can coordinate and solve this problem, There are still some difficulties. As for the parking fee, it also takes up most of the parking time for people. The traditional parking fee collection method is single and the supervision is low, resulting in a lot of arbitrary charges; Now belongs to the information age, we need to realize the parking payment function through advanced technical means. At present, many local parking lots can pay parking fees by means of handheld charging, central charging, or mobile payment. At the same time, no matter which charging mode, the parking lot charging system has the function of automatically printing charging tickets, and the whole charging process is clear at a glance. For the management of multiple local parking lots, we can manage them uniformly through the cloud platform, The real-time upload function of data is realized, which is convenient for parking lot managers to understand the operation of each parking lot in real time. At present, the functions of the intelligent parking lot management system can actually meet our parking needs. However, due to people's insufficient understanding of the functions of the parking lot system and some reasons of the parking lot itself, it becomes so difficult for people to park.

License Plate Recognition System Will Become an Innovator of Traditional Parking Lot System_ Taigewa
According to the market demand in the past two years, the license plate recognition system is growing at a double rate every year. It can be seen that the demand for the parking lot system is unspeakable. Especially in the first and second tier cities, various communities, shopping malls and other places, the parking lot system has become one of the essential facilities. The increasing demand for parking lot system has greatly promoted the expansion of security market and the development of products. When it comes to parking lot system, I believe many people will not be unfamiliar. Now many places need to use parking lot system to manage vehicle parking, which effectively prevents the phenomenon of vehicles entering and leaving at will and plays a role in safety protection for vehicle parking. Although the parking lot system is more convenient in managing vehicles, one car at a time, and can also well manage every vehicle entering and leaving the parking lot, due to technical reasons and the increasing number of vehicles in the parking lot, the use of the parking lot system in life can not meet people's parking requirements, but is easy to cause congestion when the traffic flow is large. The parking lot system based on the technical principle of license plate recognition has been gradually recognized and popularized in recent years. The biggest feature of license plate recognition is that it is safe and simple without any form of management mode. It realizes the connection with the parking lot system through license plate recognition technology, takes the license plate number as the user's vehicle identity symbol, and verifies the incoming and outgoing vehicles through the collection and storage of license plate number. In recent years, the license plate recognition system has been developed in a large range, not only in communities, institutions and other places, but also gradually towards parking places with different requirements such as large commercial squares, property groups and logistics parks, and gradually realize non-standardized customization according to different users. From the current demand, the license plate recognition system has a good prospect. Continuous technological innovation can meet the needs of more parking places.

What Should I Pay Attention to When Purchasing the Parking Lot Gate System_ Taigewang Technology
The parking lot gate system is very important for the parking lot management equipment. The main equipment of the intelligent parking lot system includes the parking lot gate, control machine, camera and other devices, and the parking lot gate system also includes the gate rod, gate movement, control motherboard, vehicle detector, anti smashing system and other components. In the process of purchasing and selecting the parking lot gate system, we should compare various product functions and consider and select from many aspects. Next, Shenzhen taigewang Technology Co., Ltd. will introduce to you what problems should be paid attention to when selecting the gate system? First, let's learn about the parking lane gate rod. At present, the parking lane gate rod is divided into straight rod, curved rod, advertising Lane gate and fence rod. The straight bar includes rubber strip straight bar and telescopic straight bar, which is suitable for a variety of scenes and has low environmental requirements; The height of the roof and the width of the road surface shall be determined for the curved rod, and the length of the main rod and the length of the auxiliary rod can be calculated only after the height is confirmed; The fence rod shall be selected according to the actual use, depending on the application scenario. Secondly, understand the anti smashing system of the gate. In recent times, we often hear news reports about the time when the gate smashes cars and people, which brings injury and loss to both sides. The anti smashing performance of the gate itself is very important. At present, the road gate has a variety of anti smashing systems, including digital anti smashing, infrared anti smashing, pressure radio wave, vehicle detector ground induction coil and other anti smashing systems, so as to reduce vehicle smashing accidents. At the same time, speed reducing devices are set at the inlet and outlet of taigewang road gate during design and installation, so that vehicles can slow down and reduce injuries when passing. Finally, understand the mechanical transmission mode of the gate. There are three modes of mechanical transmission of the gate in the parking lot: 1. Mechatronics transmission. The motor and reducer are integrated. Different motors are selected according to different rod lengths. There is no need to adjust the reducer. In case of power failure, the rod can be lifted manually, which is convenient and fast. 2. Hydraulic transmission has the advantages of simple structure, fast transmission and low noise, but the maintenance cost is relatively high. The handrail should not be too long and damaged too much. It is easy to release after power failure. It is driven by motor and decelerated by hydraulic transmission. It is generally used for highway, with high cost and good performance. Professional personnel are required for maintenance. 3. Belt drive, low cost, easy to stretch and wear, loud sound, poor transmission, daily maintenance. Motor drive, belt drive deceleration, short belt life. Power failure is troublesome; 4. The reducer has the advantages of low cost, complex structure, many parts and complex adjustment. The above is a brief introduction to the problems that should be paid attention to when selecting the parking lot gate system. Of course, the parking lot gate can be selected according to the application scenario, and the suitable one is the best to make the parking more convenient, fast and safe.
