METHOD AND SYSTEM FOR DETECTING AN OBSTACLE

Abstract:

A method for detecting an obstacle along a known path of a machine is disclosed herein. The method can include relating the location of the machine with a map. The map can include a worksite with a known path or known paths that the machine can travel on. The stopping distance of the machine can be determined and based on these identified known path and its characteristics along with a traveling speed and a weight of the machine. A LIDAR region of interest can be determined based on the stopping distance, the position and orientation of the machine, and characteristics of the known path. The machine can include a LIDAR system that can be configured to be oriented with respect to the LIDAR region of interest. A concentrated LIDAR scan can be performed to detect if an obstacle is present within the LIDAR region of interest.
