Abstract

The invention relates to the technology of unmanned aerial vehicles and provides an efficient human body tracking method for an unmanned aerial vehicle. The method comprises the following steps that 1, a remote control terminal initiates a human body tracking starting command; 2, after a human body tracking system of the unmanned aerial vehicle receives the human body tracking starting command, the human body tracking system is initialized; the human body tracking system receives video streaming input by a camera, an image of the video streaming is subjected to full-scale scanning, all human body positions are detected in the image, and all the detected human body positions are sent to the remote control terminal; 3, the remote control terminal selects one human body position which needs to be tracked, and the human body tracking system receives a tracking target and starts to enter a tracking process; in the tracking process, the unmanned aerial vehicle predicts a general position ofa current target according to flight control information, inertial sensor information and a target tracking position of a last frame of image. A vehicle-mounted flight control system and an inertial sensor are used fully, and the real-time performance of human body tracking in various scenes is guaranteed.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a human body tracking method. Background technique [0002] In the field of consumer drones, human body tracking is the basis for drones to realize advanced features such as pedestrian tracking, cycling tracking, and human-centered surround shooting. [0003] However, due to the non-rigidity of the human body itself, the difference in clothing, and the difference in shooting angles, it is very difficult to detect and track the human body based on vision. [0004] General-purpose human detection algorithms need to use more computing resources. It is very difficult to complete high-precision human detection and run it in real time in an embedded environment where there is no accelerator chip and the calculation is very limited. And due to the vibration of the drone itself and external physical disturbances (such as the influence of wind), the shooting of the drone...
