• a tool to clean the cam´s picture from false markers for calibration.

—- If your camsettings do not allow a clearer black-white picture, you may switch to the Eraser tab. Now , holding LMB on the camview window, you paint white over the cam´s picture. Do this, till calibration does not find more than the needed 25 Calibrationpoints.

Tips:

• It´s not necssary that the background is as white as eraser´s white (but nearly)
• It´s better to leave slight shadows in a bigger size, if they are of one color, for David not detects areas as points if they are bigger than
• With the RMB you can make your white paint particually undone.

You can choose its size from 1 to 99 pixels. You can not undo a single step, but only reset back to the uncleaned picture. “calibrate” works the same way as automatic calibration

Note: Sometimes, after longer continous work, the eraser stays painting when the LMB isn´t pressed any more and you don´t see it, for the picture is white on white. This may damage you cleaning prozess. Click LMB once again to be shure that eraser´s work ends.
