Abstract

The invention relates to an automatic cloth inspecting machine, in particular to an automatic cloth inspecting machine with an automatic defect detecting and recognizing system, and particularly discloses an automatic cloth inspecting machine capable of correcting image distortion based on a linear interpolation method.The automatic cloth inspecting machine is capable of correcting image distortion caused by uneven cloth feeding speed, row sampling lines are divided again at equal intervals in the warp direction on a fabric plane corresponding to images according to cloth feeding speed set by the system and serve as row sampling lines for correcting the images, and linear interpolation is conducted according to the space relation between a correcting sampling point and an original sampling point on the fabric plane to obtain gray values of all pixels on the corrected images.The method needs small operation loads and is small in memory consumption and capable of being used for real-time processing for follow-up defect recognition and processing of the automatic cloth inspecting machine.

Description

technical field [0001] The invention belongs to the technical field of automatic cloth inspection, and relates to an automatic cloth inspection machine, in particular to an automatic cloth inspection machine with an automatic detection and recognition system for defects, especially an image distortion caused by uneven cloth running of the automatic cloth inspection machine Automatic cloth inspection machine for correcting methods. Background technique [0002] At present, the detection of fabric defects is mostly done by traditional manual detection methods, which are limited by the subjective factors of the inspectors and some objective factors. low efficiency. With the rising cost of labor, the demand for automatic cloth inspection equipment is increasing. Foreign companies such as BARCO and Swiss Uster have launched commercialized automatic cloth inspection machines, but due to high prices and variety adaptability problems, domestic applications are relatively small. D...
