Abstract
The invention provides a navigation map configuration method, an obstacle avoidance method and device, a terminal and an unmanned aerial vehicle. The method comprises steps that the current flight position, the attitude information and depth maps detected at the current flight position of the unmanned aerial vehicle are obtained; the three-dimensional position information of each point is obtainedaccording to the current flight position, the attitude information and the depth maps; the three-dimensional position information of each point is projected into a partial navigation map centered onthe current flight position according to respective set weights. The method is advantaged in that job routes can be dynamically generated, and effective response to temporary mission change can be achieved.
Description
technical field [0001] The present invention relates to the field of aircraft technology, in particular, the present invention relates to a navigation chart configuration method, an obstacle avoidance method, a device, a terminal, and an unmanned aerial vehicle. Background technique [0002] With the development of science and technology, aircrafts, such as drones, are widely used in aerial photography, agriculture, plant protection, micro selfies, express transportation, disaster relief, observation of wild animals, monitoring of infectious diseases, surveying and mapping, news reports, power inspections, disaster relief, film and television It is widely used in shooting and other fields. [0003] In the traditional technology, the flight path of the aircraft is a scanning path automatically generated in advance by the ground control device according to the land plot information. Since the scan route is pre-generated, even the return path after the operation is generated b...
