Problems solved by technology

The maximum detection distance of the reversing radar auxiliary system is only about 2m, and this detection distance cannot give timely warnings for fast-approaching moving objects; in addition, the reversing radar cannot accurately detect obstacles below the installation position of the probe; and the detection range of the reversing radar is limited , unable to detect obstacles in the blind area of ​​the rearview mirror
The reversing image only provides image reference for the driver, without warning function, and the user cannot always pay attention to the reversing image

Abstract

The invention discloses a backing safety auxiliary method, device and automobile. Wherein, the reversing safety assistance method includes the following steps: collecting real-time video on the vehicle reversing route through a camera placed at the rear of the vehicle; detecting a moving object in the real-time video, obtaining the shape, size and current position of the moving object; The object is tracked to obtain the moving direction and moving speed of the moving object; according to the shape, size, current position, moving direction and moving speed of the moving object, the early warning logic judgment is carried out; and according to the result of the early warning logic judgment, an alarm is issued or not. The invention can quickly detect a moving object that appears suddenly on the reversing route and give an early warning in time, thereby improving the safety in the reversing process.

Description

technical field [0001] The invention belongs to the fields of automotive electronics and visual processing, and in particular relates to a backing safety auxiliary method, a backing safety auxiliary device and an automobile. Background technique [0002] As the number of cars continues to increase, accidents such as collisions caused by reversing are also increasing, especially in crowded parking lots and intersections. Due to the large blind spots in the rearview mirror, it is difficult to detect moving objects that suddenly enter the reversing route. Responding in time may easily cause a collision accident. Therefore, timely detection of moving objects on the reversing route and early warning can give users enough time to take measures to avoid accidents. [0003] At present, there are two main types of reversing safety assist systems: reversing radar assist system and reversing image assist system, which can improve the safety of reversing to a certain extent, but still ...
