pyCameraCalibrate

• Calibrate a camera using python and opencv.
• Calibrate a stereo camera setup.
• Calibrate a live camera, or using prior captures
• Calibrate batchs of cameras by pointing to the root folder structure containing pattern pictures, and generate a report.

Nothing fancy, just a useful tool in some circumstances..
