Method for quickly detecting raw grey cloth based on computer vision technology

The invention discloses a method for quickly detecting raw gray fabric based on computer vision technology. The method sequentially carries out Blob feature point detection on the collected images tobe detected, and judges whether a blob exists or not; performs contour detection and extraction to judge whether a communication area exists or not; and finally rotates the screenshot gray-scale integral projection to judge whether a straight line exists in the image or not. The method for quickly detecting raw gray fabric based on computer vision technology can detect various types of defects such as hook wire, hole breaking, stain, pilling, crease, yarn skipping, warp failure, weft breaking and the like, overcome the shortcomings of slow running and insufficient real-time performance of theprogram due to the fact that most of the existing techniques use a specific algorithm detection method for a specific characteristic, greatly improve the efficiency and the precision of detecting thefabric defect, improve the
