Abstract

A real-time visual tracking system is provided. An unmanned aerial vehicle (UAV) for real-time visual tracking of a moving object includes a processor, a memory coupled to the processor, and a cameracoupled to the processor and the memory, wherein the camera is used to capture video of the moving object; the UAV also includes a visual tracking module for receiving a first frame video image and afirst position of the target object and a second frame video image after receiving the first frame video image; a first search window is placed in the first frame video image and a second search window in the second frame video image, the position of the second search window in the second frame video image being the same as the position of the first search window in the first frame video image; acorrelation map between a first image block in the first search window and a second image block in the second search window is calculated; an update position of the target object in the second frame video image is determined based on the calculated correlation map.

Description

technical field [0001] This application relates generally to machine vision and, more particularly, to systems, devices and techniques for performing real-time visual tracking of objects using video images captured by cameras mounted on unmanned aerial vehicles (UAVs) or drones. Background technique [0002] Recently, civil and commercial Unmanned Aerial Vehicles (UAVs) or UAVs, a type of miniature unmanned aircraft, have gained popularity and have achieved commercial success worldwide. Unmanned aerial vehicles are usually controlled by remote control and / or software and maneuver through the sky using aerodynamic effects generated by multi-rotors, etc., while maintaining high stability while performing designed functions such as surveillance and package delivery. However, one of the most popular applications for civilian UAVs or drones is aerial photography, which is taking still pictures or recording video from a vantage point above the subject being photographed. In gener...
