The invention discloses a visual tracking method and device and electronic equipment, and belongs to the technical field of electronics. The method comprises the steps of obtaining N image feature points of a first image frame and descriptors of the image feature points under the condition that the collected first image frame is a descriptor extraction frame; descriptor tracking is carried out on the descriptor of each image feature point and M historical descriptor extraction frames, at least one first feature point and at least one second feature point are determined, and the M historical descriptor extraction frames comprise historical descriptor extraction frames within a time period of a first preset duration from the collection time of the first image frame; performing optical flow tracking on each second feature point and the second image frame; and adding each first feature point pair and each second feature point pair to a tracking feature set corresponding to the first image frame, the first feature point pair comprising a first feature point and a feature point tracked by the first feature point, and the second feature point pair comprising a second feature point and a feature point tracked by the second feature point.
Description
technical field [0001] The present application belongs to the field of electronic technology, and in particular relates to a visual tracking method, device and electronic equipment. Background technique [0002] With the rapid development of electronic technology, electronic devices such as mobile phones and tablet computers have become more and more popular, and have become an indispensable part of people's daily life. Among them, in order to improve the display effect of electronic equipment in shooting moving objects, visual tracking technology is gradually applied to electronic equipment, which obtains the motion parameters of moving objects by detecting, extracting, identifying and tracking moving objects in image sequences , such as position, velocity, acceleration and trajectory, etc., so as to realize the positioning of the moving target. However, in the visual tracking process of current electronic devices, in order to ensure the accuracy of visual tracking, it usu...
