Problems solved by technology

[0004] However, the Kinect Fusion algorithm can only perform 3D reconstruction of rigid objects
The Dynamic Fusion algorithm is improved on the basis of the Kinect Fusion algorithm, which can perform three-dimensional reconstruction of non-rigid objects, but the calculation is too large, so the calculation speed is slow, so it is difficult to achieve real-time tracking

Abstract

The present application provides an object tracking method and device, wherein the method includes: obtaining a depth map of the object to be tracked, inputting the depth map into a preset detection model, obtaining the spatial state parameter value of the object to be tracked output by the detection model, The detection model is trained using the sample depth map and the marked spatial state parameter values ​​of the sample depth map, and the sample depth map is obtained according to the preset model of the object to be tracked driven by the marked spatial state parameter values. This application has a faster response speed, which improves the possibility of real-time tracking.

Description

technical field [0001] The present application relates to the field of image processing, and in particular to an object tracking method and device. Background technique [0002] With the development of mixed reality (Mixed Reality, MR) technology, MR has been paid attention to and used in many fields. 3D reconstruction is a basic requirement of MR technology. 3D reconstruction needs to obtain geometric information of objects, such as position information and attitude information. The process of performing three-dimensional reconstruction on an object in real time is called the object tracking process. [0003] Currently, 3D reconstruction methods include Kinect Fusion algorithm and Dynamic Fusion algorithm. Among them, the Kinect Fusion algorithm performs 3D reconstruction based on the matching accuracy of the iterative nearest neighbor points of the adjacent frame point cloud. [0004] However, the Kinect Fusion algorithm can only perform 3D reconstruction of rigid object...
