Abstract

The invention relates to a method and apparatus for avoiding an obstacle automatically, wherein the method and apparatus can be applied to mobile equipment like a robot, an automatic driving device or an unmanned aerial vehicle. The apparatus comprises a first scanning ranging module, a second scanning ranging module, and a calculation module. The first scanning ranging module arranged at the top of a mobile device and the second scanning ranging module arranged at the top of the mobile device are used for scanning an obstacle around the mobile device to obtain feature information of the relative position and dimension of the obstacle. The calculation module obtains accurate obstacle features by combining obstacle features fed back by the two scanning ranging modules. Therefore, identification of the obstacle by the mobile device is realized; and thus the obstacle can be avoided effectively.

Description

technical field [0001] The invention relates to the technical field of intelligent navigation of mobile devices, in particular to a method and device for automatic obstacle avoidance. Background technique [0002] With the rapid development of the Internet of Things technology, using mobile phones or virtual reality devices to remotely control intelligent mobile devices (such as robots, autonomous driving devices or drone devices, etc.) A strong market demand broke out. For example, using a mobile phone or a virtual reality device to remotely control a household mobile robot can complete various housework operations. The related technologies of intelligent mobile devices are still immature, and how to effectively identify and avoid obstacles around them during the free movement or walking process of mobile devices has become an urgent problem to be solved. The obstacle recognition device mounted on the mobile device directly determines the intelligence and reliability of t...
