Title:
METHOD, CONTROL DEVICE, AND SYSTEM FOR TRACKING AND PHOTOGRAPHING TARGET
Document Type and Number:
WIPO Patent Application WO/2017/096949
Kind Code:
A1
Abstract:
The present invention relates to the technical field of electronic photography, and provides a method, control device, and system for tracking and photographing a target. The method comprises: in a tracking and photographing process, controlling, by a control device, a photographing device on an unmanned aerial vehicle to capture images, and acquiring the captured images; selecting a tracking target in the images; computing, according to comparison between two consecutive adjacent frames of images, a moving speed, a moving direction, and a position in a current image of the tracking target; and controlling, according to the computed moving speed, moving direction, and position in the current image, the unmanned aerial vehicle to track the tracking target, such that the tracking target is always present in images captured by the photographing device. The present invention enables automatic tracking and photographing of a target during aerial photographing without manual control of an unmanned aerial vehicle to track a moving target, thus providing high positioning accuracy, enabling tracking and photographing of a moving target, and acquiring high-quality videos or pictures.
