installation steps of license plate recognition system < / a >

The complete license plate recognition system includes license plate recognition all-in-one machine, parking lot charge display screen, intelligent gate, license plate recognition software, etc. Whether the installation of these devices is standardized or not affects the working performance of the whole license plate recognition system to a great extent

　　1. First determine the installation position of the all-in-one license plate recognition machine, which will directly affect the effect of license plate recognition. It shall be determined according to the site environment and the conditions of each entrance and exit. Usually, the camera is installed in one lane. If the direction of the vehicle entering the lane is not fixed, and the angle of the license plate recognition camera is too large, the recognition will be affected

　　2. Determine the installation position of the camera and coil: the best distance between the camera and coil is 4-4.5m from one side of the direction of the coil. The position of the coil shall ensure that when the vehicle triggers the vehicle detector, the direction of the front of the vehicle shall be inclined to the side of the camera as far as possible, so that the camera can take clear and complete photos

　　3. Determine the position of the gate and anti-collision coil: the gate is usually installed on the same side of the camera and behind the camera (installed 30cm away from the camera pole to ensure that the gate can be opened easily)

　　4. Cameras and gates should be installed on solid ground. If the ground is brick or asphalt, concrete piers shall be poured to damage the pavement and increase stability. Before installing the above equipment, the line route must be determined in advance according to the installation position of the equipment, and the threading pipe must be reserved
