Abstract

The invention discloses a vehicle precise positioning and identification method and system, comprising: acquiring real-time video information; detecting a target vehicle in real time according to the acquired video information; When the target vehicle is missed, the target vehicle is obtained; the fine category of the target vehicle and the position information of the vehicle's feature points are determined by using the convolutional neural network for the target vehicle detected in real time and the target vehicle obtained when the target vehicle is missed. Advantages: The present invention has high vehicle recall, fine vehicle classification, and precise vehicle positioning; at the same time, it controls the computational complexity of each step or module to meet application requirements; and completes the precise positioning and identification of vehicles in the vehicle ADAS scene.
