Embodiment Construction

[0048] The present invention is a multi-target tracking method in a three-dimensional space. The key points of the tracked target are distinguished by means of identification codes, and a group of high-speed cameras are used to track and locate the key points in the tracking area in the three-dimensional space. And through the motion sensor to enhance the effect of tracking prediction.

[0049] Specifically: the tracking device performs three-dimensional space tracking on the tracked target, the tracked target device is installed with an optical signal transmitter, and the optical signal transmitter generates optical signals according to the set identification code rules, and the tracking device continuously shoots through the camera The information of the optical signal is obtained by means of a method, so as to track and recognize the posture of the target device, and the posture is the three-dimensional space position and rotation of the tracked target device:

Abstract

The invention relates to a multi-target tracking method in three-dimensional space. A tracking device is used for tracking the target to be tracked three-dimensionally, the target device to be tracked is provided with an optical signal emitter, the optical signal emitter generates optical signals regularly according to the set identification code, the tracking device obtains the information of the optical signals by using a camera to shoot continuously and tracks and identifies the posture of the target device to be tracked according to the optical signals, and the posture means three-dimensional position and rotation of the target device to be tracked. A set of complete multi-target positioning and tracking solution in three-dimensional space can be better coordinated with various three-dimensional application programs. All key points are distinguished by using a coding method, therefore, more accurate tracking effect is obtained, multiple target tracking is realized, accurate positioning is achieved, direction information of the target to be tracked can be provided, and transverse displacement and rotation information of three-dimensional coordinates are acquired immediately.

Description

technical field [0001] The present invention relates to computer stereo vision (Stereo Vision), communication coding (Channel Coding), computer search technology (Computer Searching Methods), pattern recognition (Pattern Recognition) and numerical analysis (Numerical Analysis), and is suitable for the input of virtual reality and control systems The link, and the application of trajectory-oriented operation, is a multi-object tracking method in three-dimensional space. Background technique [0002] At present, the popular input devices are mainly key devices represented by keyboards and pointing devices represented by mouse touch screens. It can well meet the requirements in word processing and daily office use, but in the increasingly hot field of three-dimensional processing, peripheral devices that use symbols or two-dimensional coordinates as input signals cannot well adapt to this trend. However, the existing 3D input systems have deficiencies in real-time performance,...
