The License Plate Recognition System also Has the Function of Judging Whether There Is a Car Through

Some license plate recognition systems also have the function of judging whether there is a car through video images. The vehicle detection part of the parking lot license plate recognition system usually adopts ground induction coil or radar. It is called video vehicle detection; License plate recognition and identity recognition range from simple magnetic card, smart card, electronic tag, paper ticket, automatic license plate recognition and other methods, from single identity recognition in the past to a combination of multiple recognition methods, such as the combination of smart card and license plate recognition. The gate products adopted by the license plate recognition and charging system have leakage maintenance function, which can protect the grounding current and overvoltage of the control system, It is equipped with ground sensor support and socket, which can be used when the ground sensor is plugged in. Overall features: stable, smooth, quiet, safe, high performance and long service life. Convert analog signals into digital signals. At present, the image acquisition of license plate recognition parking lot system mainly adopts the camera to connect the image acquisition card or directly connect the portable notebook for real-time image acquisition. The situation is essentially caused by different strategies adopted by the people in each bureau. Therefore, the combination of different strategies adopted by the people in each bureau is defined as a situation. Monitoring the situation evaluation of the license plate recognition system is the core function of the information game fusion model. Taking into account the conflict and the same in the process of cooperation. The payment value under the situation of license plate recognition system is used as the quantitative measure of situation evaluation. Through gray-scale and binary processing, the character segmentation of Shanghai HD license plate recognition system: after locating the license plate area in the image- Character region, and then character segmentation is carried out according to the character size characteristics. The fixed vehicle license plate number can be directly imported into the HD license plate recognition all-in-one camera. The license plate number recognition system monitors the license plate recognition system. The management of Shanghai license plate recognition all-in-one machine is more convenient and safe: for parking lot users with only fixed vehicles. When fixed vehicles enter and leave the parking lot; In recent years, the technology of intelligent license plate recognition in license plate recognition system has developed rapidly. As for its recognition basis, it can be divided into indirect recognition technology research and direct method: indirect method is based on IC card (i.e. radio frequency identification) (Reid or bar code based identification. Therefore, the development and application of the parking lot management system is very necessary. The demand overview adopts the induction card parking lot management system, and a set of entrance and exit management equipment is set at the entrance and exit of the parking lot to make the parking lot form a relatively closed place;
