PCI three-dimensional analysis module oriented implantation type ture three-dimensional stereo rendering method

Abstract

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-dimensional scene 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.

Description

technical field [0001] The invention relates to the technical field of three-dimensional visualization, in particular to an implantable true three-dimensional rendering method for PCI three-dimensional analysis module software. Background technique [0002] With the development of computer technology, stereoscopic display has become a commonly used technical means in the fields of environment simulation, simulation training, planning and design, etc., and even began to combine with movies and computer games to produce stereoscopic movies and true 3D games to integrate into people's daily life. As an important spatial data, the superimposed display of satellite images and DEM can produce realistic three-dimensional effects. PCI is a remote sensing analysis and processing software launched by the Canadian Apollo company. The three-dimensional analysis module can realize the fusion display of satellite images and terrain, and carry out 3D flight simulation. [0003] It is a tr...

Problems solved by technology

However, due to the need for professional equipment, the high cost also limits the application of stereoscopic display technology, so the application of stereoscopic display cannot be promoted, and a large number of 3D programs are still displayed using single-channel technology, which lacks stereoscopic effect and loses the three-dimensional program. Stereoscopic display characteristics

At the same time, because stereoscopic display requires special hardware and special programming skills, a large number of programs have not considered the characteristics of stereoscopic display during development, and have not implemented the function of supporting stereoscopic display in the program. Stereoscopic display is not possible on the hardware

These programs occupy the vast majority of the current 3D display programs, and the PCI 3D analysis module does not break through the above limitations. During the modeling process, the user can only see the perspective 3D of a single channel, and cannot achieve true 3D stereoscopic display. Cannot achieve optimal application effect
