Abstract：
The invention provides a method and device for decoding implicit structured light, and the method comprises the steps: carrying out the traversal of an image photographed by a camera, and obtaining the gray value and ideal neighborhood gray distribution of each pixel point; according to the gray values of the pixel points and the ideal neighborhood gray distribution, completing stripe extraction in combination with a preset output image, and outputting an updated output image; classifying stripe center points in the updated output image to obtain a stripe classification result; determining a corresponding relation between stripes in the updated output image and stripes in the structured light image according to a stripe classification result; and decoding all stripe center points by utilizing an epipolar constraint method and combining the corresponding relationship between the stripes in the updated output image and the stripes in the structured light image. According to the scheme, the hidden structured light image can be decoded efficiently and robustly on the basis of ensuring the precision.
