Re: Vision problem - robot view not matching Grip view
The reason for this is that OpenCV actually modifies the Mat passed into it when running findContours. Since the Mat from the HSV Threshold is passed into findContours directly, it modifies the Mat that is being sent to the dashboard.
The solution to this is to create a new Mat in the class (call it hsvSend or something like that). Then at the end of the HSVThreshold function, call hsvout.copyTo(hsvSend);. Then putSource the hsvSend mat instead of the hsvout mat
hsvout might not be the right name, I don't remember. But it's just the one that is the output from the inRange function.
As another hint, you are HIGHLY overexposing your image. Either lower the voltage to your light source, or lower the exposure on the camera. It will make tracking much easier and more reliable.
