What Are the Requirements and Characteristics of License Plate Recognition Camera Embedded in Intell

Intelligent license plate recognition camera is an embedded intelligent high-definition license plate recognition camera product specially launched for the parking lot industry. It is highly integrated with license plate recognition algorithm, lens, fill light and protective cover. It adopts high-definition wide dynamic CMOS and tidsp, and the peak computing power is up to 6.4ghz. Based on the license plate automatic exposure control algorithm, the imaging is excellent. It has the characteristics of excellent performance, multi-function, high adaptability and strong stability.

It is the best application form of car parking management system license plate recognition function. I. recognition requirements of license plate recognition system: small license plate recognition (90-120 pixels) and large license plate recognition (120-160 pixels). Full resolution capture of the on-site vehicle photo triggered for recognition, and the width of the license plate (the pixel size of the license plate can be displayed by framing the license plate through the drawing software). II. Engineering principle of license plate recognition system: the best straight-line distance: the straight-line distance from the lens of license plate recognition camera to the outside of ground sense, generally within 3-6M. III. engineering requirements of license plate recognition system: 1. Erection height of all-in-one license plate recognition machine: the general standard is 1.5m-1.8m; 2. License plate recognition camera column: installed on the inner side of the gate, about 50cm away from the gate rod, to prevent the gate rod from blocking the camera capture, thus affecting the recognition effect; 3. Wiring: network line, power line, ground sensing switching value signal line (connected to vehicle inspection output terminal). 4. Location of deceleration belt: 1) when the ground sense of the integrated license plate recognition machine triggers recognition: install the deceleration belt at about 1m outside the ground sense at the entrance and exit to ensure that the front of the following car does not touch the ground sense; 2) when video stream triggers recognition: install the deceleration belt between 3.5-5m away from the gate, and slow down the speed to ensure the best recognition distance and license plate recognition rate. In order to prevent the owner from following the car too close, a warm prompt board should be erected and kept 3 meters away. 5. External fill light: the column height is 0.6m, installed at 50cm-80cm on the inner side of the ground sensor (keep the fill light on the front of the license plate), which can be reflected on the license plate by shooting on the ground sensor coil to ensure the recognition effect of the license plate. 6. Monitoring picture (bottom inclination): try to keep the width of the license plate parallel to the horizontal, and the maximum angle shall not exceed 15 & deg;. According to the application cases and experience of license plate recognition system for many years, the manufacturer of tigerwong license plate recognition system summarizes the following points: 1. When the vehicle enters the image capture area, the vehicle is facing the camera, and the effect is the best; 2. The place where license plate recognition is installed shall have sufficient straight-line distance to facilitate installation and commissioning. This distance can be calculated as follows (vehicle length optimal recognition distance of camera); 3. Avoid 90° Install license plate recognition system equipment after turning; 4. Avoid installing license plate recognition system equipment on uphill and downhill; 5. Avoid the chaotic environment on site and install this system (there are many pedestrians, and pedestrians often enter and leave the vehicle passage, which is easy to cover the license plate); 6. Avoid the channel with serious water and sewage on the road when it rains (it is easy to block the license plate). Tigerwong parking management system has focused on parking equipment for many years!
