Abstract

A tracking system of positional attitude consists of tracking object with infrared luminous unit having multiple distinguishing points distributed on tracking object, image collecting unit with infrared cut-off filter and video camera, image processing unit for identifying out current positional attitude according to distribution character of infrared luminous unit based on collected infrared images.

Description

technical field [0001] The invention relates to a position and posture tracking system, in particular to a position and posture tracking system for human-computer interaction. Background technique [0002] At present, the most common position and attitude tracking system used for human-computer interaction in foreign countries is the optical position and attitude tracking system, and most of the optical position and attitude tracking systems are based on the principle of computer vision. Theoretically, for a point in space, as long as it can be seen by two cameras at the same time, the position of the point in space at this moment can be determined according to the images and camera parameters captured by the two cameras at the same time . When multiple points of an object are determined simultaneously, the attitude of the object in space can also be determined. When the camera shoots continuously at a sufficiently high rate, the motion trajectory of the point or object ca...
