The invention discloses a blind area identification method and device. Firstly, target point cloud data collected by unmanned equipment is acquired; secondly, aiming at each target point cloud point contained in the determined target point cloud data, according to a scanning angle when a laser radar arranged on the unmanned equipment detects the target point cloud point, determining an area which takes the target point cloud point as an initial position and is far away from the unmanned equipment according to a direction in which the unmanned equipment points to the target point cloud point; and taking as an extension area corresponding to the target point cloud point. And then, according to the extension area corresponding to each target point cloud point in the target point cloud data, identifying a data acquisition blind area of the area where the unmanned equipment is located when acquiring the target point cloud data. According to the method, the data acquisition blind area of the area where the unmanned equipment is located when the unmanned equipment acquires the target point cloud data can be determined, and the unmanned equipment is prevented from colliding with other surrounding obstacles, so that the safety of the unmanned equipment in the driving process is improved.
Description
technical field [0001] This specification relates to the field of unmanned driving, and in particular, to a blind spot identification method and device. Background technique [0002] In practical applications, part of the field of vision of the unmanned equipment may be blocked by obstacles during driving. For example, when the unmanned equipment is driving, the surrounding large vehicles will block a large area of vision, and the large vehicles will pass by. When a pedestrian suddenly appears from the blind spot of the field of vision, there is a possibility of a collision with a pedestrian. At present, unmanned equipment cannot determine its own blind spot, which will cause unmanned equipment to collide with surrounding obstacles, making unmanned equipment less safe during driving. [0003] Therefore, how to improve the safety of unmanned equipment during driving is an urgent problem to be solved. SUMMARY OF THE INVENTION [0004] This specification provides a blind ...
