Parking Lot Management System License Plate Recognition Charging System in the Community - Tigerwong

With mature and reliable science and technology, honest and rigorous work attitude, small profit and long-term business philosophy, the parking lot management system always adheres to the tenet of "high-quality products and excellent service". Provide customers with high-quality and cost-effective products and services to help customers increase benefits and enhance the added value of property management. At present, automatic license plate recognition is more and more widely used in parking lot system, said the manufacturer of parking lot management system. Automatic license plate recognition is an automatic pattern recognition technology for license plate number and license plate color by collecting dynamic video or static images of vehicles. A complete license plate recognition system should include vehicle detection, image acquisition, license plate recognition and so on. The core of automatic license plate recognition system technology includes license plate location algorithm, license plate character segmentation algorithm and optical character recognition algorithm.

When the vehicle detection part detects the arrival of the vehicle, trigger the image acquisition unit to acquire the current video image. The license plate recognition unit processes the image, locates the license plate position, segments the characters in the license plate for recognition, * and forms the license plate number output. At present, there are three main application modes of license plate recognition in parking lot management system: video recognition mode, ground induction coil recognition mode and video ground induction recognition mode. The parking lot management system manufacturer said. 1 The amount of work of video recognition mode is small. When the vehicle enters the video recognition area, the advantage of video trigger is that there is no device ground sensing coil.

The camera automatically recognizes the license plate information through the dynamic image of the vehicle, and provides simulation trigger recognition at the same time. The disadvantage is that the image cannot be output for unlicensed vehicles, and it is easy to miss vehicles. If the license plate is not recognized, you can manually click the simulation trigger for recognition. 2 The ground induction coil identification mode is generally triggered by the ground induction coil. A deceleration belt will be set about 10 meters in front of the parking lot gate. The vehicle decelerates through the deceleration belt to allow time for license plate recognition.

The vehicle enters the recognition area, triggers the ground induction coil, automatically commands the camera to capture, identifies the license plate through self character detection, and the gate is released. The ground induction coil triggered license plate recognition has the advantages of high trigger rate, not easy to miss vehicles, practical and stable performance, and can output image records for unlicensed vehicles. The disadvantage is that the ground sense of the construction device is required and the engineering quantity is large. 3 Video ground sense recognition mode video plus ground sense recognition mode is recognized by video recognition mode, which is an upgraded version of the first two modes. Upload through ground sense trigger. Compared with the ground sensing coil recognition and video recognition mode, the video ground sensing recognition mode can provide faster recognition speed and higher recognition rate. The recognition mode of flexible switching of video ground sense.

At present, the flexibility * recognition mode is applied to delimit the recognition area and output area through software, and freely set the output position of license plate according to the customer's site environment, which can solve the problem of car following recognition and fire output too early. When an unlicensed vehicle travels to the output area, the information of an unlicensed vehicle can be easily recorded. However, it is not easy to occupy a place in the parking lot charging system, although the market of license plate recognition in intelligent parking lot system is very large. Based on the enterprise itself, if it can not break through the homogeneous parking lot equipment product line, perhaps entering the service market is another good choice. However, the early investment in the service market of intelligent parking lot management system is different from that in the hardware market. Its early investment is large and the profit recovery is slow.

All Wuhan parking lot system enterprises must consider the risk.
