Example Embodiment
[0055] Example 1
[0056] The first step is to collect the status video image of the rail
[0057] The 800*600 resolution CCD camera is used to collect the status video images of the railroad tracks. The camera has 30 frames per second and uses LED supplementary light. The number of acquisitions is 8 times / day, and the length of each acquisition video image is 8 minutes;
[0058] The second step is to process the captured video images of the rail status
[0059] 2.1 Preparation before processing
[0060] Compress and transmit the state video image of the railroad track collected in the first step to the control processing host, calculate the conversion rate at the current computer resolution, that is, convert the pixel unit for the computer to calculate or analyze the image into the international unit mm / per pixel, The conversion rate is 0.0776mm / pixel;
[0061] 2.2 Early video image processing
[0062] 2.2.1 Open the video, and capture the last frame of the state video image of the rail...

[0087] Example 2
[0088] The first step is to collect the status video image of the rail
[0089] A 1024*768 resolution CCD camera is used to collect the status video image of the railroad track. The camera has 35 frames per second, uses LED supplement light, and the number of acquisitions is 10 times / day, and the length of each acquisition video image is 10 minutes;
[0090] The second step is to process the captured video images of the rail status
[0091] 2.1 Preparation before processing
[0092] Compress and transmit the state video image of the railroad track collected in the first step to the control processing host, calculate the conversion rate at the current computer resolution, that is, convert the pixel unit for the computer to calculate or analyze the image into the international unit mm / per pixel, The conversion rate is 0.0776mm / pixel;

[0119] Example 3
[0120] The first step is to collect the status video image of the rail
[0121] A 1440*900 resolution CCD camera is used to collect the status video image of the railroad track. The camera has a frame rate of 40 frames per second, uses LED supplementary light, and the number of acquisitions is 12 times / day, and the length of the video image collected each time is 8 minutes;
[0122] The second step is to process the captured video images of the rail status
[0123] 2.1 Preparation before processing
[0124] Compress and transmit the state video image of the railroad track collected in the first step to the control processing host, calculate the conversion rate at the current computer resolution, that is, convert the pixel unit for the computer to calculate or analyze the image into the international unit mm / per pixel, The conversion rate is 0.0776mm / pixel;
[0125] 2.2 Early video image processing
