Abstract

The embodiment of the invention discloses a parking space detection method and device based on vision. Linear information is obtained by using an LSD algorithm, part of interference line segments are filtered out according to the width of a parking space line, a parking space is searched through the constraint relation between the line segments, and the position of the parking space is calculated. According to the scheme of the embodiment, the influence of the interference lines on the parking space searching process can be reduced, the parking space can be accurately searched according to the constraint relation between the parking space lines, and then the vehicle is guided to be automatically parked.

Description

technical field [0001] The invention relates to the technical field of smart cars, in particular to a vision-based parking space detection method and device. Background technique [0002] With the advancement of science and technology, the automobile industry has developed rapidly and is constantly progressing in the direction of intelligence. Today, with the increasing number of cars, automatic parking has gradually become an indispensable function of the car itself. The automatic parking technology can minimize accidents such as scratches and collisions caused by human parking, and at the same time make the vehicle accurately positioned, making parking safer and more accurate. [0003] The traditional automatic parking system uses sensors such as ultrasonic radar to detect surrounding obstacles and vehicles, selects the parking position and direction according to the detection results, and then performs subsequent path planning for automatic parking; however, this method ...
