Tigerwong, a High-quality R & D Team of License Plate Recognition System

Parking lot management system, license plate recognition system, intelligent all-in-one card system, intelligent video system and other fields have a high-quality R & D team. Years of dedicated operation has accumulated a lot of R & D experience and on-site implementation experience. Have complete system development and design and production capacity of supporting equipment. The system has been widely used in commercial buildings, property communities, shopping malls, hotels, hospitals, campuses, factories, government agencies, tourist attractions and other fields. It provides quite good, perfect and stable system solutions according to the functional needs of users. It has been favored by many users. The license plate recognition system has developed for several years. The license plate recognition system is widely used. Based on its application status, this paper introduces the main contents of license plate recognition technology in detail, hoping to give readers some reference. Its software core includes license plate location algorithm, license plate character segmentation algorithm and optical character recognition algorithm. Some license plate recognition systems also have the function of judging whether there is a car through video images, which is called video vehicle detection. Automatic license plate recognition is a pattern recognition technology that uses the dynamic video or static image of the vehicle to automatically recognize the license plate number and color. The hardware foundation of license plate recognition system generally includes trigger equipment (monitoring whether the vehicle enters the field of vision), camera equipment, lighting equipment, image acquisition equipment, disposal machine (such as computer) for recognizing license plate number, etc. The inductance of the coil shall be kept between 100uh-300uh. When the coil inductance is constant, in order to make the detector work in the best state. The number of turns of the coil has an important relationship with the circumference. The smaller the perimeter, the more turns. Since various metal substances such as cable pipelines, steel bars and sewer covers may be buried under the road, which will have a great impact on the actual inductance value of the coil, the data in the above table are only for users' reference. During actual construction, the user shall use the inductance tester to actually test the inductance value of the inductance coil to determine the actual number of turns during construction, as long as the final inductance value of the coil is within a reasonable working range (such as between 100uh300uh)
