License Plate Recognition System, License Plate Recognition - Tigerwong

License plate recognition system license plate recognition all-in-one machine 800MHz DSP and arm are connected to the main controller, * soni1 / 2.5-inchti3730 chip (1ghzcortex-a8 Hankou license plate recognition. 2 megapixel full real-time, standard h.265mainprofile coding, dual code stream, SD card storage, and can be recognized within 6 meters of channel width; making on-site device debugging more convenient and fast; * automatic focusing. Switch freely according to the on-site environment of each device; * support video stream and trigger recognition. * fixed users / temporary users can charge offline; * full range of license plates Can be recognized (blue, yellow, police, single and double deck and Guangdong, Hong Kong and Macao license plates) *Optimized embedded license plate recognition algorithm: the comprehensive recognition rate is higher than 99.8% * support large angle recognition of channel environment 60 ; * excellent automatic imaging control: automatically track light changes, effectively suppress forward and backward light; suppress car headlights at night; automatically turn on and off without human setting; * intelligent lighting supplement. The entrance of the integrated control display system displays welcome, remaining parking spaces License plate number, 32-bit MCU core chip, which integrates control, voice, display, gate opening and billing. Gate opening command output; human voice output; monochrome two-line Chinese and English LED display. The size of display area: 260 * 130mm; the size of display box: 350 * 630 * 100mm determines whether the license plate recognition system is easy to use.

It must be clearly recognized that the important point is that the recognition rate reaches 100 .% impossible, because the license plate is dirty, blurred and blocked, a background management system of license plate recognition system. Or the weather may be bad (snow, hail, fog, etc.) The functions of the background management system should include: when the multi-functional system operation makes the network error, it can maintain that the image data will not be lost, 1. The reliable storage of recognition results and vehicle image data. At the same time, it is convenient for manual troubleshooting afterwards; the recognized vehicle license plate number should be automatically compared with thousands of license plate numbers in the database and prompted for alarm, 2. Effective automatic comparison and query Technology. If the license plate number is not read correctly, it is necessary to use fuzzy query technology to get a relatively "appropriate" Comparison results; it also needs to provide real-time communication, network security, remote maintenance, dynamic data exchange, automatic database update, hardware parameter setting and system fault diagnosis. 3 a good license plate recognition system is widely used for networked operation. Based on digital image processing, pattern recognition, computer vision and other technologies, license plate recognition is a modern intelligent transportation system The license plate recognition system is one of the important parts of the parking lot license plate recognition.

It analyzes the vehicle image or video sequence taken by the camera to obtain the license plate number of each vehicle, so as to complete the recognition process. Through some subsequent disposal means, it can realize the parking lot charge management, traffic flow control index measurement, vehicle positioning, vehicle anti-theft and high-speed public transportation Automatic supervision of road speeding, electronic police for running red lights, highway toll stations and other functions. It has practical significance for maintaining traffic safety and urban public security, preventing traffic congestion and realizing traffic automatic management. According to the configuration functions, the license plate recognition system is divided into: some products meet the needs of users. The license plate recognition system will add other personalized functions, such as rotating ticket box , is a kind of ticket box specially designed for the convenience of car owners to pick up their cards, which can judge the parking distance of vehicles.

It is full-featured, domineering, and has an atmospheric appearance. It can be equipped with luminous light sources on both sides; toughened glass panels, and a new process. The price of the license plate recognition system in the parking lot is scratch and burst proof; three-layer spraying process. It adopts automobile paint. Product parameters: working voltage: DC12 V working environment temperature: - 25 - 60 relative humidity: =
