How Does the License Plate Recognition System Deal with Image Imaging in Different Environments_ Tai

In recent years, the increasing number of private cars has also promoted the vigorous development of the parking industry. As the core technology of intelligent parking lot, license plate recognition is the core of the whole parking lot system. The parking lot managed by the license plate recognition system has been popularized to all fields of our life, so more advanced recognition technology will bring more convenience to people. However, due to the influence of the natural environment, the license plate recognition technology will still be affected. At present, the factors affecting the license plate recognition and imaging are different. 1. The brightness at night is not strong, and the light is not scattered under the action of the night headlights, The license plate image may become black and white. In order to solve this problem, the intelligent fill light technology which relies on algorithm to control the fill light is usually used. At the same time, double width dynamic is used, so that the license plate recognition camera can capture more bright and dark details on the same screen, which is closer to what human eyes can see. 2. Due to the influence of weather, the visibility in rainy and foggy weather is low, and the quality of the obtained license plate image will be seriously degraded. Therefore, the license plate recognition system must realize the image restoration function, that is, the image restoration algorithm is used to reproduce the degraded image in rainy and foggy days. 3. For the large angle formed by vehicle operation due to different traffic directions, the license plate recognition system of individual manufacturers is not ideal for this situation. This problem is particularly obvious in parking lots with turns and wide entrances and exits. Of course, the arc of large angle can be reduced by controlling the height and angle of license plate recognition camera, However, it can not completely solve this problem. Delida parking lot license plate recognition system can effectively solve this problem. 4. For forward and backward light, the exposure parameters of the camera can be adjusted through intelligent light control technologies such as local exposure and strong light suppression, so as to achieve excellent automatic imaging control.
