Distortion calibration in Asura 2.0



Please educate me. Is this how we should make measurements with the moai_calib_1.apc file?

Do we measure from outer to outer wall of the squares or just the distance from each other (inner sides)?

I also wanted to know the correct orientation of X and Y. Sorry for the stupid question, but is the photo below correct?


For the calibration file you need the center-to-center distance of the two cubes. So you need to measure the distance between the outer two walls and the thickness of the two cubes and calculate the center-to-center distance from that.

Your second picture with the axes is wrong. X axis goes from bottom left corner in your picture to top left corner (Post A to post B), Y axis goes from bottom left corner to bottom right corner ( Post A to Post C).


Squeeze the jaws lightly against one of the square pegs and while continuing to hold it there, press the zero button. Now measure across the outside of two pegs as you have shown in the photo. The reading will be the center-center distance of the pegs if the squares have the same dimensions.

If you want absolute precision, repeat while using the other peg as a zero reference and calculate the average of the two measurements. This will adjust for differences in the pegs.


In Asura 2.1, we will use an updated algorithm to give more points to calibrate. will folow up soon


Any updates with the new calibration method for asura 2.1?


not yet. give us a bit time. we expect to get it out this weekend.
