Abstract

The invention relates to a feature point observation window setting method, tracking method, device, equipment and medium based on an image pyramid. Based on the tracking convergence state obtained by tracking, the preset size adjustment step is obtained. Based on the tracking convergence state, the initial size and the size adjustment step are used to set the size of the observation window of the current layer image. The tracking convergence state of tracking reasonably sets the size of the observation window of the current layer image, and realizes the dynamic setting of the observation window of each layer image, so that the size of the observation window can be changed flexibly. Based on this flexible observation window, the feature points can be improved. The flexibility of tracking and the dynamic setting of the observation window according to the tracking convergence state are also conducive to reducing the tracking time of feature points while ensuring accurate tracking of feature points.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image pyramid-based feature point observation window setting method, an image pyramid-based feature point observation window setting device, an image pyramid-based feature point tracking method, and an image pyramid-based feature point Tracking devices, computer equipment and computer readable storage media. Background technique [0002] In computer vision systems, feature texture matching is an important image processing task. Feature texture matching refers to extracting some feature textures in multiple images. These feature textures are called feature points, and then match these feature points. [0003] Traditional technology usually finds the moving speed and direction of the corresponding feature points by detecting the change rate of pixel intensity under a fixed-size observation window with time, so as to realize the tracking of the feature points.
