Can anyone point me to some equations for determining how to use a reference object (a simple cross) to determine the angle of the camera in reference to the plane to which it's attached, and how to measure other points in the same frame to correct for perspective distortion? The basic idea is for developing the equations required to make a floating camera an optical micrometer based on the cross reference itself. Mounting the camera perfectly flat at the object isn't practical as it needs to be handshooting, the cross would basically to help correct for the very subtle perspective shift I'm thinking multiple crosss, then the user would point out to the image software where the crosses were and it'd use edge detection from there to determine it's exact dimensions. Then you would point out the pixels on the other dimensions in the field to be measured to get the dimensions and perspective correction.
