As mentioned in the previous article, license plate locating is based on an example in the opencv sample. I think it is theoretically feasible, but I have never performed any operations. Today I am free. I modified the code and tried several images. I found that the effect is good. The code is specially pasted to communicate with opencv learners and hope to give some guidance with high fingers. O (partition
, can identify identity cards, driving licences, business cards and other identification documents, as well as vehicle driving license, license plate number and other vehicle information. With the camera support and video triggering, automatic classification function, can achieve rapid batch acquisition of identity card information.Functional Features:

4.3 The improvement method in this paper
Through the introduction of the above two methods, it can be seen that the horizontal projection method for the only connected characters and no interference in the license plate has a good segmentation effect, and the complexity of the algorithm is relatively simple, but for the inclusion of non-connected or sticky characters in
In this tutorial, I'll take you to use Python to develop a license plate recognition system using machine learning technology (License Plate recognition). What we're going to do.
The license plate recognition system uses optical
At present, the technology of license plate recognition is quite mature. In the last one months of study time, the entire license plate recognition process went through, there is a relatively clear, comprehensive understanding.
