To measure the distance between the two red points in the image above, follow these steps:

  1. Obtain the pixel coordinates of the two vertices.
  2. Utilize the “Convert Lengths Pixel-Wise to Physical” Step to calculate the actual physical distance.

For data collection, it is essential to have a calibration board positioned in the plane where the line segment to be measured is situated. Follow these steps:

  1. Use a Step like “Detect Line Segments” to determine the pixel coordinates of the endpoints.
    Input the line segment and an image containing the calibration board.
  2. Set the appropriate parameters as specified in the documentation.
  3. Retrieve the actual length measurement.
    Please refer to the Docs for specific details regarding the parameters: https://docs.mech-mind.net/en/suite-software-manual/1.7.4/vision-steps/convert-lengths-pixel-wise-to-physical.html
