Augmented reality technology Implementation method based on physical detection and tracking algorithm

Abstract

The invention discloses an augmented reality technology Implementation method based on physical detection and tracking algorithm. The method comprises the following steps that a local marker file is generated, an augmented reality system is initialized, an image of a real scene is acquired, the edge of the image is extracted and optimized, template match is conducted on the edge of the image, and if the matching succeeds, a decision window in the region is generated, a position matrix corresponding to the template is imported, the position matrix is conducted to fine adjust and amend, the special effect of the augmented reality is rendered according to the amended position matrix, corners are extracted in the decision window, appropriate tracking algorithms are chosen according to the number of the corners, If the number of the corners is larger than the threshold value, the system enters the feature point tracking algorithm. If the number of the corners is smaller than the threshold value, the system enters the edge tracking algorithm, animation effects of the augmented reality are updated according to the tracking algorithms, different tracking algorithms are adopted according to the number of the corners, then the detection and tracking for three-dimensional physicals are achieved when rich feature points do not exist or without feature points.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a realization method of an augmented reality technology based on an object detection and tracking algorithm. Background technique [0002] The full name of Augmented Reality technology is Augmented Reality, that is, AR. It is a technology that integrates information such as visual effects, sound effects, and spatial information in the virtual world into real environmental information. Augmented Reality technology not only displays the information of the real environment, but also integrates The virtual information is displayed, and the two kinds of information are complemented and superimposed, so that the user can obtain richer perceptual information. Usually, electronic devices equipped with augmented reality technology can use the camera configured on it to The lens captures the images of the real environment, and calculates the position and angle of the captured images in real ...

Problems solved by technology

However, there may not be rich feature points in the 3D object, or even extreme cases without feature points, such as the 3D printed model, which interferes with the matching of the object. Therefore, the detection of the object based on the feature points and Tracking has limitations
