The invention relates to the technical field of raw silk detection, and particularly discloses a raw silk electronic detection method based on machine vision, which comprises the following steps: conveying detection raw silk to be detected through a traction device, and sequentially passing through an image acquisition system, a rough hair imaging system and a humidity detection system; image photos shot in different directions are transmitted to an upper computer, data detection of detected raw silk is realized through a built-in software platform of the upper computer, and light and shadow formed by the detected raw silk and standard raw silk can be mapped to an imaging panel through a designed rough hair imaging system, so that the detection of the raw silk and the standard raw silk is realized. Two shadows mapped on the imaging panel can be shot through the industrial camera and transmitted to the upper computer, and the shadows formed by the detection raw silk and the shadows formed by the standard raw silk are compared, so that whether the rough hair on the detection raw silk is larger than the rough hair on the standard raw silk or not can be better compared.
Description
technical field [0001] The invention relates to the technical field of raw silk detection, in particular to a machine vision-based electronic detection method for raw silk. Background technique [0002] Due to the particularity of raw silk, during the production process of raw silk, it is necessary to carry out sampling inspection on the raw silk, and judge whether the raw silk of this batch meets the production standard by inspecting the appearance of the raw silk. This method is time-consuming and labor-intensive and is prone to visual fatigue, which leads to a decrease in the detection effect. With the rapid development of machine vision, pattern recognition, and image analysis technology, industrial automation inspection is gradually replacing manual inspection. However, the existing technology of detecting the quality of raw silk through machine vision is not mature enough, and the inspection process is relatively simple and single. , it is difficult to accurately obta...
