Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below. Apparently, the described embodiments are only some of the embodiments of the present invention, but 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.

[0032] The blind spot warning method based on the steering state provided by the embodiment of the present invention is mainly applicable to the situation where the blind spot warning strategy is adjusted through the vehicle-mounted BSD camera and the front wheel angle when the vehicle is turning. The blind spot warning method based on the steering state provided by the embodiment of the present invention may be executed by an electronic device integrated...

Abstract

The invention relates to the field of safe driving, and discloses a blind spot early warning method, device and storage medium based on steering state. The method includes: collecting the images taken by the vehicle-mounted BSD camera, and identifying the images to obtain the position of the pre-collision object; according to the front wheel angle of the vehicle and the current vehicle speed, determining the dangerous area of ​​the vehicle on the steering side; Determine the common range of the dangerous area and blind area mapping, and the target pre-collision object in the common range; increase the original distance threshold between the target pre-collision object and the vehicle body, and obtain the updated distance threshold; adopt the The updated distance threshold is used to give an early warning for the target pre-collision object. In this embodiment, when the vehicle is turning, the blind spot warning is used to reduce the accident rate.

Description

technical field [0001] The present invention relates to the field of camera calibration, in particular to a blind spot early warning method, device, equipment and medium based on steering state. Background technique [0002] The vehicle-mounted BSD (Blind Spot Detection, blind spot monitoring) camera (hereinafter referred to as the camera) is installed on both sides of the rear of the vehicle, and is used to detect the blind spots on both sides of the rear of the vehicle when the vehicle is driving. The early warning strategy is: identify the distance of pedestrians or vehicles relative to the body through the images captured by the on-board BSD camera, and give an early warning when the distance decreases to the set value. [0003] When the vehicle turns, the driving trajectory changes, and the dangerous area increases compared with when going straight. According to the existing early warning strategy, the incidence of accidents will increase. In view of this, the present ...
