Abstract

The embodiment of the invention discloses a target tracking method, which comprises the steps of using a presetting algorithm to extract the corner feature of a reference image to obtain the first feature point set of the reference image, removing abnormal points which exceed the range of images to be matched from the first feature point set to obtain a second feature point set, matching the second feature point set with the images to be matched and finishing the target tracking of the images to be matched according to matching results. The embodiment of the invention additionally discloses a target tracking device. By using the target tracking method and the target tracking device, the extracted corner feature has good identifiability and stability, the matching speed is greatly improved, the feature point set of the reference image is optimized, the corners which exceed the range are removed, the problem that the matching cannot be realized due to a reason that the feature points exceed the range in the prior art is solved and the matching reliability is improved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a target tracking method and device. Background technique [0002] Object detection technology is also commonly referred to as image feature extraction. It is a concept of computer vision and digital image processing. It refers to the image information extraction process that uses computer operations to determine whether the pixels of each image are image features. The target tracking technology is to determine the position of the region of interest (Region Of Interest, ROI) also known as the template (Template) in the video image or continuous image sequence, and correspond to the template of each frame of image. [0003] The existing tracking technology solutions can be described as follows: [0004] (1) Determine a template in the collected image sequence, which is usually called a reference image, and the target to be tracked is recorded in the reference image; [0005] (2) ...
