Traffic sign detection method and related equipment

Abstract

The invention provides a traffic sign detection method and related equipment, and the method comprises the steps of compressing a high-resolution traffic real scene image directly collected in the vehicle driving direction through a local vehicle-mounted terminal, reducing the image resolution, and carrying out the main traffic sign detection of an obtained to-be-detected image with a lower resolution; after a first main traffic sign in a traffic real-scene image is positioned, obtaining a potential image area of a first auxiliary traffic sign matched with the detected first main traffic sign in the traffic real-scene image according to priori knowledge of a main traffic sign detection result, and performing auxiliary traffic sign detection on the potential image area, therefore, the auxiliary traffic sign detection result is quickly and accurately obtained, the target position information mapped to the traffic real-scene image is obtained, the real-time performance and accuracy of vehicle control or road guidance achieved according to the target position information are improved, the calculated amount of the whole traffic sign detection process is very small, and the invention can be implemented locally by the vehicle terminal with poor computing power, and networking is not needed.

Description

technical field [0001] This application relates to the field of intelligent transportation applications, in particular to a traffic sign detection method and related equipment. Background technique [0002] Nowadays, with the application of intelligent transportation systems in scenarios such as intelligent driving and unmanned driving, map service devices usually provide road guidance data for vehicle terminals based on the traffic conditions between the starting position and the target position of the vehicle, so as to Guide the vehicle to drive safely and smoothly to the destination. [0003] Taking the map navigation scene as an example, usually the vehicle terminal is connected to the network and sends a navigation request to the map service device, so that the map server responds to the navigation request, determines the corresponding road image collected by the map collector using the image collection device, and feeds it back to the vehicle The terminal displays to ...

Problems solved by technology

[0004] However, in practical applications, due to various factors such as the external environment or the vehicle-mounted terminal itself, the network communication between the map service device and the vehicle-mounted terminal is often abnormal, and problems such as data delay or reception failure occur, thereby reducing the speed of vehicle navigation. real-time and reliability, and even threaten the driving safety of self-driving vehicles
