Problems solved by technology

This processing scheme consumes a lot of time in calculation, and the detection efficiency for a single scene such as the road boundary is relatively good, but for the detection of pedestrians, vehicles and other obstacles on the road, the time consumption is very large
[0006] These methods have limitations. The detection accuracy based on visual information will decrease in the case of weak light. The other two radar-based methods have slow processing speed and consume a lot of time for large-scale point cloud data processing. longer time

Abstract

The embodiment of the invention relates to a quick barrier detection method. The method comprises the steps that a two-dimensional grid map is established on the basis of point cloud data of a three-dimensional radar, the attributes of grids are calculated to determine impassable areas, points of which the scanning line gradient values exceed predetermined threshold values in the impassable areas are determined as barrier points, and correlation clustering is conducted on the barrier points by traversing the grid map.

Description

technical field [0001] The disclosure belongs to the technical field of computer vision and laser radar data processing, and in particular relates to a method for fast obstacle detection. Background technique [0002] The detection of obstacles in traffic scenes is of great significance for unmanned vehicles and / or robots to accurately perceive the surrounding environment information and make safe driving decisions. Obstacle detection based on visual information is highly dependent on the environment. In the case of poor lighting or bad weather, the captured video will have a greater impact on the result detection error. Therefore, this disclosure chooses to use the method based on 16-line lidar data for detection. The method based on 16-line lidar has many advantages. On the one hand, the data acquired by lidar has strong anti-interference ability and is less dependent on the environment. On the other hand, compared with other types of lidar, the price of 16-line lidar i...
