Hi, I need to do image calibration between two known points on an image.
Let's say that we have those two points [130,799] and [602,799], where the first are rows and then the columns. I know I need to use the euclidean distance equation like this
So assuming
y1 = 130y2 = 602x1 = 799x2 = 799distanceInPixels = sqrt( (x2-x1).^2 + (y2 - y1).^2);
How do I combine all those stuff and finally get the calibration factor of mm/pixel.
Please help.
