The invention provides a computing-imaging-based three-dimensional information acquisition method for an optically invisible scene. According to the method, a computing imaging technique and an active three-dimensional sensing method are combined and no complex operation like stereo matching is needed. The method comprises steps of generation of a projection structure light stripe, calculation and reconstruction of a carrier deformation stripe, and acquisition of three-dimensional coordinate information of a measured. The system is realized by a digital projector, a camera and an optically invisible scene. The computing-imaging-based three-dimensional information acquisition method has advantages of high precision, simple device, and realization of shielding or coverage breaking and is capable of realizing three-dimensional information acquisition of an optically invisible scene.
Description
technical field [0001] The invention relates to a three-dimensional information acquisition technology, in particular to a method for acquiring three-dimensional information of an optically invisible scene based on computational imaging. Background technique [0002] The 3D information acquisition technology can obtain the 3D coordinates of the measured scene at the same time, which has important practical significance and broad application prospects in the fields of physical profiling, industrial inspection, virtual reality, machine vision and intelligent interaction. The traditional 3D information acquisition technology is aimed at the measured scene is an optically visible scene, based on the principle of photogrammetry, using passive 3D sensing method or active 3D sensing method to obtain the 3D coordinate information of the measured scene. However, in the actual industrial inspection, fire rescue and other environments, the measured scenes are mostly blocked or covered,...
