Cannot Calibrate

[andrewgleave]

When I follow the docs and attempt to calibrate a color by clicking on the indicator in the side panel and then clicking on the appropriate dot picked up from the calibration page, nothing happens.

I can see by looking at LocalStorage that nothing is being set and keyPoints here is always zero-length.

Others seem to be having no problem but this has me stumped. Is there anything obvious I could be missing?

[paulsonnentag]

I tried to replicate your problem but it worked for me. Could you share what's stored in localStorage.paperProgramsConfig?

[andrewgleave]

Sure.

I managed to get it to calibrate by moving the camera much further away. Maybe I could have changed config.paperDotSizes to reduce the relative size of the dot for detection purposes?

[janpaul123]

Ah, the config.paperDotSizes seem tricky. We should allow calibration of pages that are close up to the screen.

[paulsonnentag]

I think the problem is that if the paper dots are significantly bigger than the default size of 8 they are removed from the list of potential paper dots and instead recognized as markers. A quick fix would be to set the default marker size to something unrealistically high like 9999.
