Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] In view of the traditional algorithm architecture used in the existing technology, the strategy of using gradient regression tree point-by-point regression combined with global constraint rules to extract key points of vehicles can only be adapted to the situation where the image is clear, the body is correct and there is no occlusion in the bayonet or electric police scene , it is impossible to effectively extract large-angle low-quality vehicle ...

Abstract

The invention provides a vehicle key point alignment method based on deep learning. Characteristic point regression is carried out on areas such as vehicle windows, vehicle lamps and license plates ofa vehicle by utilizing a strong characteristic extraction capability of a deep convolutional network. And the vehicle key points are subjected to geometric matrix operation to obtain a vehicle alignment matrix, so that the vehicles are corrected and aligned to the same angle and direction, and the vehicle alignment effect is completed. The vehicle key point alignment method is high in feasibilityand high in real-time performance, the extracted key points can effectively represent the overall situation and detail information of the vehicle, and the aligned vehicle images are beneficial for improving the recognition rate of a subsequent classification recognition algorithm.

Description

technical field [0001] The invention belongs to the technical field of computer vision processing, in particular to a vehicle key point alignment method based on deep learning. Background technique [0002] With the development of artificial intelligence and computer vision technology, vehicle recognition technology has been widely used in many image detection and public security systems, such as bayonet system, electronic police system, intelligent transportation and automatic driving and other fields. However, due to the complex outdoor lighting environment and the reality of vehicles traveling in multiple angles and directions, vehicle recognition technology is prone to misidentification. What needs to be solved urgently is to improve the accuracy of vehicle recognition. Therefore, preprocessing and correcting vehicle images to provide better vehicle images for algorithm recognition is a feasible way to improve the recognition rate. [0003] There is currently only one p...
