Abstract: An optical measurement equipment includes an adjustment apparatus and at least two image capturing devices. The image capturing devices have a depth-of-field and attached to the adjustment apparatus. The image capturing devices are adjusted by the adjustment apparatus such that a portion to be measured of a workpiece is located within the depth-of-field of the image capturing devices.

Abstract: An apparatus includes: a first image capture module, a second image capture module, and a first projector. The first image capture module has a first optical axis forming an angle from approximately 70° to approximately 87° with respect to the surface of a carrier. The second image capture module has a first optical axis forming an angle of approximately 90° with respect to the surface of the carrier. The first projector has a first optical axis forming an angle from approximately 40° to approximately 85° with respect to the surface of the carrier.
