PROCESSING METHOD FOR LINE PATTERN USING CONVOLUTION KERNEL, PROCESSOR FOR LINE PATTERN, AND MEDIUM STORED WITH PROGRAM FOR EXECUTING THE PROCESSING METHOD FOR LINE PATTERN

摘要

PROBLEM TO BE SOLVED: To eliminate noise by processing a line pattern with an image generated by structured light. SOLUTION: The line pattern processor 200 includes a kernel learning part 260 for deciding a kernel-like and optimum threshold for each longitudinal section of an image by using a simple line pattern formed at a predetermined position, a convolution application part 270 for applying a convolution to a captured actual test image, by using the decided kernel-like and optimum threshold, and an area selection part 280 which if a plurality of pixel groups having pixel values other than zero are present, when scanning longitudinally a pixel column included in the image that the convolution has been applied to, sets the pixel value of a pixel group other than a single pixel group selected from among the plurality of pixel groups as zero.
