Problems solved by technology

[0004] The purpose of the present invention is to address the shortcomings in the above-mentioned prior art, and propose an adaptive invisible structured light technology implementation method. In the present invention, the invisible structured light can automatically obtain the optimal result according to the specific conditions of each image , and apply this adaptive method at the pixel level to calculate the most suitable color channel and brightness value for embedding structured light. The present invention overcomes the two major problems of image dependence and lack of precision respectively.

Abstract

A self-adapting invisible structure light technology implementation method belonging to a computer projected information embedding technology field comprises: 1. adjusting an original image brightness spatial scope; 2. pixel level self-adapting embedding the invisible structure light in a pseudo original image generated in step 1; 3. capturing a mutual compensation image by using a camera head, performing a pixel level self-adapting analytic invisible structure light to the image by using a C2P correspondence mapping method; 4. processing the analytic structure light image by using a median filter, and removing redundant error points. The brightness effect of the invention is closer to the original image, which is difficult to perceive by human eyes, at the same time, the invention respectively overcomes two problems of image dependence and precision deficiency.

Description

technical field [0001] The invention relates to a method in the technical field of computer projection information embedding, in particular to a method for realizing an adaptive invisible structured light technology. Background technique [0002] The full name of invisible structured light technology is "Embedding Imperceptible Structured-Light Patterns Technology". Compared with traditional structured light technology, this technology is characterized in that it is difficult for human eyes to perceive the structure of this technology. However, the high-frequency camera operating synchronously with the projector can capture and recognize the structured light image information embedded in the image. Under the condition of high-speed projection, the human eye can hardly detect the structured light pattern information embedded in the original image. In this way, the work of calibrating the relative position of the projector and the projection plane, and even the work of obtain...
