License plate recognition system in the parking lot will encounter more special usage scenarios

Now the license plate recognition system mainly through the license plate recognition cameras to extract the vehicle information, and the camera captures images because of the interference of external environment is relatively complicated, so make out the speed of the license plate number, large influenced its clarity and accuracy.In order to solve the resolution to increase the ability of recognition from the algorithm layer do targeted with different scenarios.The license plate recognition system in the parking lot will meet what is the use of special scenes?

a, large Angle recognition

large Angle recognition is parking environment technology of license plate recognition system is more difficult.Because the license plate recognition system in the parking lot on the large Angle shooting rectangular plate of the vehicle, the license plate image usually is not gained by the rectangular images, it is need to modify the deformation image.Imaging distortion caused by the large Angle plates is generally regarded as one of the technical problems in the license plate recognition.


2, identify the speed will be affected by the image pixel

license plate license plate recognition camera distance, the smaller the pixels, the closer, the pixels, the greater the parking lane is shorter than that of the other scenario, and the recognition of license plate recognition system is real-time, under the condition of ensure rapid recognition support to identify the contradiction between large pixel width of plates is typical.License plate pixels wide, usually recognition is very slow, and to identify speed, license plate pixel width will be within a certain range.
