Embodiment Construction
[0037] Such as figure 1 , 2 , 3, 4, 10, 11, 12, 13, 14, 15, a kind of fabric physical performance detection method based on machine vision of the present invention may further comprise the steps:
[0038] a. The area array camera 7 equipped with the telecentric lens 7-1 is arranged face to face with the LED light source 12, and a detection area 16 is formed between the area array camera 7 and the LED light source 12, and the LED light source 12 is an infrared light LED light source , the area array camera 7 is an infrared area array camera,
[0039] b, the area array camera 7 is controlled by the computer 17,
[0040] c. Pass the tested fabric 3 through the detection area 16, the LED light source 12 shines on the tested fabric 3, and the area array camera 7 takes pictures of the tested fabric 3 (see Figure 10 ),
[0041] d, the image taken by the area array camera 7 is transmitted to the computer 17, and the image of the tested fabric 3 is converted from a time domain ima...
