Abstract: A pattern of symbols is generated and sent to a projector, wherein the pattern includes an array of symbols having a given number of symbol columns and symbol rows, and an image is obtained from a camera. Next the image is decoded in order to generate a decoded pattern of symbols and the depth map is generated as a function of the pattern and the decoded pattern. The image is decoded by placing an array of classification windows on the image and determining the displacement of each classification window in order to optimize a given cost function. Finally, the decoded pattern is generated by determining a respective symbol for each classification window.

Abstract translation: 生成符号图案并将其发送到投影仪，其中图案包括具有给定数量的符号列和符号行的符号阵列，并且从相机获得图像。 接下来，对图像进行解码，以便生成解码的符号图案，并且根据图案和解码图案生成深度图。 通过将分类窗口阵列放置在图像上并确定每个分类窗口的位移以便优化给定的成本函数来解码图像。 最后，通过确定每个分类窗口的相应符号来生成解码图案。
