Abstract
A measurement system ( ) has a camera with a lens ( ) and a separate sensor ( ) mounted so that their planes ( ) intersect at an object plane ( ) according to the Scheimpflug principle. A reference camera( ) is normal and provides a 2D normal image which is used by an image processor ( ) to determine a calibration image. This allows the image processor to determine height of the object ( ). A single image capture provides an image of the full object, such as a ball grid array (BGA).
