Mech-MSR 3D Measurements

Hello,

I am using Mech-MSR version 2.1.0 with the Mech-Eye LSR XL-GL. There is no robot being used with this setup. The working distance from the camera to the part is 2280mm to 2500mm and I am inspecting the edges of a box and the bottom side of the calibration grid.


When using the ‘Fit Line to Surface Edge’ step, there will be instances where the fitted line is above or below the surface of the part, as shown below:


I have tried adjusting the size of the 3D ROI as well as the individual settings for the tool itself, but I can’t get this to consistently lineup with the edge.

Secondly, there will be times when either the power cycles or I disconnect then reconnect to the camera that the ROIs have shifted. I am not sure what is causing this so I can’t give a good way to replicate this issue.

I am also working with Calculate Results by Python and am wondering if there is a way to have the thresholds from a previous Step be inputs for the Python step. It would make coding and keeping track of changes a lot easier to do.

Any suggestions would be greatly appreciated.
