Abstract

The invention discloses a vehicle accurate positioning and recognition method and system. The method comprises the steps: real-time video information being acquired; detecting a target vehicle in real time according to the acquired video information; processing the vehicle detected in the continuous frame scene of the video information, and obtaining a target vehicle when the target vehicle is missed; and determining the fine category of the target vehicle and the feature point position information of the vehicle by using the convolutional neural network according to the target vehicle detected in real time and the target vehicle obtained during missing detection of the target vehicle. The method has the advantages that the method has high vehicle recall, fine vehicle type classification and accurate vehicle positioning; meanwhile, the calculation complexity of each step or module is controlled, and the application requirements are met; and accurate positioning and identification of the vehicle in the vehicle-mounted ADAS scene are completed.

Description

technical field [0001] The invention relates to a vehicle precise positioning and identification method and system, belonging to the technical field of vehicle precise positioning and identification. Background technique [0002] Vehicle identification and positioning is an important part of the vehicle assisted driving system, and there are still some problems such as missed vehicle detection, vehicle classification and vehicle regression are not detailed enough. How to effectively improve the detection rate of vehicles and at the same time refine the classification and feature point positioning of vehicle models is an important research direction of vehicle assisted driving systems. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a method and system for precise vehicle positioning and identification. [0004] In order to solve the above technical problems, the present ...
