Abstract
This invention provides a 3D laser capture system, and method for employing the same, that avoids a shadow effect and allows for straightforward set-up and use of the system in imaging the surface profile of an object. A camera is provided with a head assembly that includes a lens configuration and a pair of mirrors that generate two simultaneous views, of opposite object sides. The two views are projected by the mirrors and lens configuration onto discrete portions of the camera's image sensor. The separate images captured on each of the two portions of the sensor are both analyzed by the systems vision system processor, thereby allowing the processor's profiling algorithm to analyze the surface from two different viewing angles concurrently. Portions of the laser blocked in one view are generally visible in the other view. Alternatively, a second lens can be employed to provide a second field of view.
