Machine vision-based on-line detection device and detection method in textile weaving forming

The invention relates to the technical field of textile knitting detection, in particular to an online detection device and method in textile knitting forming based on machine vision. The device comprises a shell, a feeding roller and a receiving roller. A woven and formed cloth blank is fixed to the feeding roller and penetrates through the shell to be connected with the collecting roller. The shell comprises a first visual capturing area and a second visual capturing area, wherein a first image shooting device is arranged at the top of the first visual capturing area. The second vision capturing area comprises a second image shooting device arranged at the top of the second vision capturing area and a movable light-emitting assembly, the movable light-emitting assembly is arranged at the bottom of the second vision capturing area, the cloth blank makes contact with the movable light-emitting assembly when passing through the second vision capturing area, and a plurality of light-emitting parts are arranged
