Vehicle re-recognition method and system based on vehicle front windshield sticking signs

Abstract

The invention discloses a vehicle re-recognition method and system based on vehicle front windshield sticking sign. Implementation of the method comprises the steps of taking pictures of a vehicle front windshield, inputting the pictures into a deep training detector to perform detection and positioning, and acquiring a candidate region of front windshield sticking signs; performing detection and positioning on the candidate region of the front windshield sticking signs by using the detector, acquiring candidate regions of each sign, and counting the number and color sequence of the signs; and calculating relative positions of the signs and a central point of each vehicle front windshield picture. If two vehicle front windshield pictures are consistent in number and color sequence of the signs and a difference value of the relative positions is within a preset value, vehicles in the two pictures are judged to be the same vehicle, otherwise, the vehicles are judged to be different vehicles. According to the invention, the pictures are inputted into the deep training detector to perform detection and positioning, and vehicle recognition is performed based on the vehicle front windshield sticking signs, so that the vehicle re-recognition method and system have high accuracy and anti-interference ability and are high in adaptability.

Description

technical field [0001] The invention belongs to the technical field of digital image processing and pattern recognition, and more specifically relates to a vehicle re-identification method and system based on a sticker on a front windshield of a vehicle. Background technique [0002] The development of the times, along with the development of urbanization, the increase of my country's urban population, the number of cars in the city is increasing day by day, which poses a huge problem for my country to build a smart city, especially to improve the ability of intelligent traffic management. In intelligent traffic management, vehicle information needs to be identified in aspects such as road checkpoints and parking charges. Vehicle re-identification refers to the technology of extracting vehicles from different images to distinguish the similarities and differences of vehicles. Among them, the use of mature license plate recognition system for vehicle information extraction h...
