Multi-source time-series layered coding method based on color structured light

Abstract

The invention relates to a multi-source time-sequence layered coding method based on color structured light, characterized in that, for color coded structured light patterns, the color code information value (R, G, B) used, that is, the color three-channel information value , respectively: the coded value corresponding to the red color code (R, G, B) = (255, 0, 0), the coded value corresponding to the green color code (R, G, B) = (0, 255, 0), and the coded value corresponding to the blue color code The coding value corresponding to the color code (R, G, B) = (0, 0, 255), the coding value corresponding to the cyan color code (R, G, B) = (0, 255, 255), the coding value corresponding to the magenta color code (R, G, B) = (255, 0, 255), the coded value corresponding to the yellow color code (R, G, B) = (255, 255, 0), the coded value corresponding to the white color code (R, G, B) = (255, 255, 255); Avoid color texture color information from interfering with color structured light.

Description

technical field [0001] The invention relates to a multi-source time-series layered encoding method based on color structured light, which belongs to the technical field of computer vision. Background technique [0002] In the research of structured light 3D reconstruction technology, in order to improve the accuracy and efficiency of 3D reconstruction, the coding method of structured light has transitioned from the multi-frame Gray phase-shift coding method to the single-frame color coding method, and the single-frame color coding method uses the color code The rich information to set the uniqueness of the code value. However, the single-color-coded structured light method is usually applied to light-colored or white objects. If the surface texture of the object to be tested is rich in color, it will cause color information interference to the color-coded color code value. Therefore, in the later decoding process In , severe reconstruction bias occurs. In order to avoid co...

Problems solved by technology

Although the above method can reduce the interference problem of the color code caused by the texture color of the object to be tested to a certain extent, it more or less involves the problem of pre-calibration of the color channels of the projector and camera in the early stage. There will be various problems in the pre-calibration process. The interference of external factors, but also related to the auxiliary projected image
