Drivable space judging device and method thereof

Abstract

The present invention relates to a drivable space judging device and a method thereof. The drivable space judging device comprises: a laser distance sensor mounted on a vehicle to detect an area at a certain distance in front of the vehicle to generate distance information; a signal processing unit that generates plane distance information from the distance information generated by the distance sensor; a margin stone detection unit that detects edge stones by judging the correlation and similarity between the generated plane distance information and previous plane distance information; and A judging unit that judges whether the curb path detected by the detection unit is within the driving area, and whether the area at a certain distance in front of the vehicle is a space for driving.

Description

technical field [0001] The present invention relates to a drivable space judging device and method thereof, in particular to a drivable space judging device and method for detecting curbs and obstacles on the driving path of an unmanned autonomous vehicle and judging whether the path is drivable space. Background technique [0002] Unmanned autonomous vehicles generally detect obstacles in the direction of travel for safe driving, and use the detected information to determine the direction of travel. But self-driving vehicles are driven outdoors for a specific purpose, so avoiding collisions with obstacles formed on the ground becomes a critical factor. [0003] This unmanned autonomous vehicle needs to detect the boundary stone between the vehicle and the sidewalk, that is, the curb, to avoid collisions with sidewalks that protrude higher than the sidewalk when driving on the lane. The curbstone is an important sign on the road, as long as the curbstone can be found accura...

Problems solved by technology

[0009] However, the application of the above-mentioned traditional technology can only detect and identify a certain area of ​​the vehicle and identify the rear space moving in the range sensed by the distance sensor. driving space

[0010] In addition, the recognition rate of the section where the height of the edge stone becomes lower decreases, and it is impossible to simultaneously measure each section of the edge stone in real time.
