Problems solved by technology

[0004] Visual tracking mainly has the following problems: (1) the tracked object is viewed from different angles, or under different lighting conditions, or the tracked target is not a rigid body, then its image will be different; (2) if the tracked target is different from the background If the color or texture is similar to the background, it is easy to be confused; (3) the tracking target is lost due to occlusion or image frame loss; (4) the motion state of the tracked target changes suddenly
At present, computer vision technology is not perfect, and these problems will lead to tracking failure, so there is currently no general visual tracking method

Abstract

The invention relates to the technical field of unmanned aerial vehicles, and particularly discloses a method of realizing real-time visual tracking on a target based on an image color and texture analysis. The method comprises a step of extraction and analysis of image features in which proper visual features are extracted according to the texture and the color of the image, significant features of the target in a scene are analyzed and extracted, and reference is provided for design of a tracking algorithm, a step of design of the target tracking algorithm in which the reasonable target tracking algorithm is designed according to a visual feature analysis result, the target tracking algorithm adopts a color tracking algorithm or a texture tracking algorithm and application conditions of the tracking algorithm are brought forward, and a step of target matching and recovering in which the proper target features are used for visual matching to judge the accuracy of the tracking result. When target occlusion or image loss happens, the target can be recovered through full image search. A visual tracking method is designed for a specific application situation, and high-reliability tracking on the target is thus realized.

Description

technical field [0001] The invention relates to the technical field of visual tracking, in particular to a real-time visual tracking method for a target based on image color and texture analysis. Background technique [0002] In recent years, drone technology has developed rapidly and is gradually being used in various industries and has become a mass consumer electronic device. Computer vision technology has been developed for many years and has been widely used in industrial fields.
