camera_calibration - override enough data check

Hi everybody,

I'd like to calibrate a stereo rig with the camera_calibration stereo node. I have a set of pre-recorded images that I publish using a simple ad-hoc player node and with some datasets it works pretty well. I followed stereo tutorial and if the number of images in my sequence is enough no problem arises. The problem is when I do not have enough frames and the calibrate button never lights.

Do you know how I can override the good enough check?

Thank you, Augusto

It looks like there is a magic number of 40:

self.goodenough = (len(self.db) >= 40) or all([p == 1.0 for p in progress])

Change it to zero or whatever you like (clone the the image_pipeline pipeline into your catkin_ws and catkin_make it, if devel or install is sourced it should take precedence over the unmodified image_pipeline elsewhere on your system when you rosrun/launch it).

You could also probably fake it by send the same images repeatedly until 40 is reached.

Thanks, it works like a charm ;-)
