What Kind of License Plate Recognition System Is a Good License Plate Recognition System Tigerwong T

In recent years, the continuous improvement of private car ownership has driven the vigorous development of the parking lot industry. As the benchmark of the whole parking lot industry, license plate recognition has become more and more widely used with the gradual development and maturity of intelligent license plate recognition system. So, what kind of license plate recognition system is a good license plate recognition system? At present, the construction level of parking lots in China is uneven. Most of them use open entrances and exits, the light and shadow situation is complex, and the large angle of license plates formed by vehicle operation makes it more difficult to identify license plates. How to improve the license plate recognition rate in extreme scenes has become a difficulty that the industry has been trying its best to overcome, It is also an important factor to distinguish the quality of the parking lot license plate recognition system. The difference of environment, driving at night, the pros and cons of light and the angle of vehicles entering and leaving the parking lot all affect the imaging effect of license plate recognition, and the influencing factors of imaging effect under different scenes are different: first, the difference of environment, low visibility in rainy and foggy weather, and the quality of license plate images obtained 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. II. When driving at night, under the action of headlights, the image of license plate may become black and white. To solve this problem, the intelligent fill light technology of algorithm control fill light is usually used. At the same time, double width dynamics is adopted, so that its license plate recognition camera can capture more bright and dark details in the same picture, Closer to what human eyes see. III. forward and inverse of light for forward and inverse 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. IV. the angle of vehicles entering and leaving the parking lot. For the large angle formed by vehicle operation, the treatment effect of the license plate recognition system of individual manufacturers is not ideal. This problem is particularly obvious in the parking lot with turns and wide entrances and exits. However, through the control of the height and angle of the license plate recognition camera, It can reduce the radian of large angle, but it can not completely solve this problem. In addition, it has to add algorithm recognition. Tigerwong license plate recognition algorithm increases the recognition processing of deformed characters, and makes special treatment for this problem. Coupled with the local exposure function, it has a better effect in identifying license plates with large angle. The optimization of the algorithm in extreme scenarios greatly improves the recognition rate and applicability of license plate recognition in multiple environments and angles. It is also the condition that a good license plate recognition system should have. The user experience is the most important.
