Abstract

The invention provides an obstacle detection method and device, a computer readable storage medium and a processor, and the method comprises the steps: obtaining a to-be-recognized point cloud which is the point cloud of an object in the visual field of a depth camera; calculating a ground plane equation in real time according to the to-be-identified point cloud, wherein the ground plane equation is an equation of the current ground under a robot coordinate system; a plane corresponding to the ground plane equation is moved by a first preset value in the positive direction of the Z axis of the robot coordinate system, and a segmented plane is obtained; determining a preparation obstacle point cloud according to the segmentation plane, wherein the preparation obstacle point cloud is a to-be-recognized point cloud located on one side, close to the positive direction of the Z axis of the robot coordinate system, of the segmentation plane; and the prepared obstacle point cloud is identified, the obstacle point cloud is determined, and the obstacle point cloud is the point cloud calibrated as an obstacle. The method solves the problem that in the prior art, due to the low reliability of a ground plane equation, missing detection and false detection of obstacles are caused.

Description

technical field [0001] The present application relates to the technical field of point cloud processing, and in particular, to an obstacle detection method, device, computer-readable storage medium, and processor. Background technique [0002] At present, manufacturing factories are developing in the direction of automation and intelligence. In some scenarios, AGVs replace the role of traditional manual handling. AGV belongs to a kind of small automatic driving equipment in a specific scenario, which needs to detect the state of the surrounding environment. At present, the perception of AGV has become an indispensable role. In the factory floor or warehouse, the environment is difficult to remain unchanged. There may be various unknown obstacles on the path planned by the AGV. The perception layer needs to identify these obstacles near the AGV in a timely and accurate manner. Common AGV external environment perception sensors include lidar, sonar, monocular camera, binocula...
