Generating Calibration Board #5

Closed KenR22 closed 2 years ago

KenR22 commented 2 years ago

Hi I am trying to generate calibration board from this site: https://markrmakr.herokuapp.com/charuco_board However, on the annotation toolbox there is a parameter called side length. I was wondering what that would correspond to if I use a board from the website mentioned.

Also do you know of any better option for generating charuco boards?

Thanks

Hi! The side length is the length of a single checkerboard square (e.g. one of the black ones) in millimeters. In the calibration board generator you linked I'm assuming this is the 'Length of a black square in [mm]' parameter. I would suggest to print out the board and measure the length on the final printed board to make sure the length you're entering into the AnnotationTool is accurate.

I usually recommend calib.io, but I don't think it's better or worse than the website you're using.

I actually started with Calib io but I got a bit confused about the dictionary argument in the Jarvis as Calib io does not offer the argument. i.e. 4x4_1000(could not find the where I would input the 1000)

Thanks again.
