The invention provides an obstacle avoiding method of unmanned equipment, a device and a system, the obstacle information around the unmanned equipment collected by a sensor is obtained in real time. A maximum safe movement speed, a small safe movement speed, a relatively safe range, and a danger range are obtained. When obstacle information is in the danger range, the unmanned equipment is switched to enter into an obstacle avoiding driving mode. When the obstacle information is in the relatively safe range, the unmanned equipment is controlled to be in a normal driving mode. When the obstacle information is not in the danger range and is not in the relatively safe range, the unmanned equipment is controlled to be in the normal driving mode. Thus, according to the obstacle information, the maximum safe movement speed, the small safe movement speed, the relatively safe range and the danger range, the unmanned equipment can be switched to enter into an obstacle avoiding driving mode or the normal driving mode, and the collision accidents of the unmanned equipment can be effectively reduced.
Description
technical field [0001] The present invention relates to the field of unmanned equipment control, in particular to a method, device and system for unmanned equipment to avoid obstacles. Background technique [0002] Unmanned equipment includes drones (unmanned aerial vehicles or unmanned aircraft), unmanned vehicles and other smart devices with certain self-control functions. They have been widely used in civilian and military fields since World War II and after their invention. . Currently, commercial UAVs already exist, especially rotary-wing UAVs such as quadruped aircraft. Most drones have similar functions, such as altitude control, automatic position holding against wind, automatic waypoint patrol, follow function to monitor moving people or objects, etc. [0003] An important function that a self-driving device must have is obstacle avoidance to keep it safe and prevent it from colliding with objects or people. Among them, commercial unmanned equipment has an obstac...
