Summary: | The invention discloses a method and system for quickly measuring a bending radius of a spacecraft cable. The method comprises the steps of obtaining images of a to-be-measured cable and a measurementstrip through photographing; determining the type of the to-be-measured cable based on the RGB value of the to-be-measured cable in the image and the one-to-one correspondence between the RGB value of the preset cable and the type of the cable; obtaining the ratio of the RGB value of the measuring strip in the image to the radial size and the axial size of the annular ring of which the differencebetween the RGB value of the cable to be measured is greater than a preset threshold, and calculating the diameter of the cable; obtaining the bending radius of the bending part of the to-be-measuredcable based on the edge track; judging whether the bending radius meets the standard requirement or not according to the ratio of the bending radius to the diameter. Through technical paths of photographing, identification and |
