Problems solved by technology

Although a single color-coded structured light can quickly perform three-dimensional reconstruction of the object to be tested, this type of method faces a class of problems, that is, when the surface texture of the object to be tested seriously interferes with the color-coded color code, it will make the single-color image The coded structured light 3D reconstruction method fails, and at this time, if multiple gray codes and other methods are used for 3D reconstruction, there will be a problem that the projector projects more coded patterns

Abstract

The invention relates to a high-adaptability color object three-dimensional reconstruction method which is characterized in that a camera and a projector are fixed to a three-leg support; the camera is connected with a computer through a cable; the projector 3 is connected with the computer 1 through a cable; a computer is used for generating a colorful coded structural light pattern; multi-sourcesequential layering processing is performed; then decoding processing is performed on a multi-source sequential layered pattern; through combination, a modulated single colorful coded structural light pattern is obtained; then a strip matching method is used for realizing matching of coding characteristic points; and finally a triangulation method is used for realizing three-dimensional depth information value resolving of the coding characteristic points. The high-adaptability color object three-dimensional reconstruction method realizes similarity to a realizing process of a single colorfulcoded structural light and furthermore reduces the number of coded patterns which are projected by the projector to a certain extent.

Description

technical field [0001] The invention relates to a highly adaptable three-dimensional reconstruction method of a colored object, which belongs to the technical field of computer vision. Background technique [0002] The structured light 3D reconstruction method is an active 3D measurement technology realized by a projector and a camera. It projects a pre-designed coding pattern onto the surface of the object to be measured through the projector. The pattern produces modulation deformation. At this time, the camera is used to collect the modulation pattern, and then combined with the corresponding decoding method and system parameters, the depth information value of the point on the surface of the object to be measured can be determined in space. Structured light 3D reconstruction technology can reconstruct objects with high precision and non-contact measurement, which has become one of the important methods for 3D free-form surface measurement. At present, with the rapid dev...
