Problems solved by technology
[0002] At present, most of the computer systems that realize 3D three-dimensional interaction are based on optical positioning cameras, which can obtain the position and attitude information of the interactive pen in the three-dimensional space in real time, and calculate the position of the interactive pen in the real three-dimensional space coordinate system according to a certain algorithm. The virtual space position of the interactive pen is mapped in the established virtual three-dimensional space coordinate system, but the accuracy of the 3D three-dimensional interaction still needs to be improved

The invention provides an interactive pen detection method and a 3D interactive system, and relates to the technical field of three-dimensional interaction. The invention provides the interactive pendetection method and the 3D interactive system. The method comprises the steps of based on the binocular vision positioning principle, obtaining the space coordinates of an optical mark point on the interactive pen in a sight distance range of the positioning camera; obtaining an included angle between the interaction pen and a geomagnetic field three-dimensional coordinate system according to a magnetometer in the interaction pen; by the transformation of the optical coordinates, obtaining an included angle between the orthogonal ray of the display and a geomagnetic field three-dimensional coordinate system, so that the pen point of the interactive pen can be determined according to the spatial coordinates of the optical mark point in the sight distance range of the positioning camera, and the relative direction of the pen point relative to the display can be detected according to the included angle between the orthogonal ray of the display and the geomagnetic field three-dimensionalcoordinate system, and accordingly the spatial positioning accuracy of the interactive pen and the accuracy of the interactive operation are improved.
