The invention relates to an implanted actual three-dimensional rendering method oriented to a PCI three-dimensional analysis module, comprising: adopting implanted rendering data interception technology between calling of 3D API adopted by the PCI three-dimensional analysis module and display of a display card to capture an original single-channel color signal, a depth signal, a three-dimensionalscene transformation matrix and a projection transformation matrix; analyzing the information to reconstruct grid three-dimensional data; based on the stereoscopic vision principle, self-adaptively retransforming the scene to two different view point positions so as to form a binocular vision stereopair for stereoscopic display, and driving the display card to carry out stereoscopic output on the binocular vision stereopair; and utilizing polarization, red-green and blinking type glasses and the like to carry out actual three-dimensional display and observation. The method can realize the actual three-dimensional scene display for the current PCI three-dimensional analysis module under the condition of not changing programs and operation modes.
