MR virtual space image acquisition method

The invention provides an MR virtual space image acquisition method, which comprises the following specific steps: S1, converting an MR virtual space coordinate system into a camera coordinate system taking an optical center of a three-dimensional space acquisition camera as an original point, and measuring an external space world by a visual angle of the camera; s2, constructing a pixel coordinate system taking the optical center of the three-dimensional space acquisition camera as an original point, viewing an MR external space world from the visual angle of the camera, and projecting points of the external space world on an imaging plane coordinate system; and S3, finally converting points in the MR virtual world coordinate system into points in a pixel coordinate system, and completing MR virtual space image acquisition. According to the method, one-by-one labeling and definition are not needed, the working efficiency is improved, conversion and correspondence of the coordinate system are completed when t
