Perspective distortion

Perspective distortion refers to a phenomenon of spacial perception that plays an important role in photography. If perspective distortion is not controlled, “converging lines” may occur, especially in architectural pictures. The resulting photo shows e.g. a building façade tilting backwards. Thus, street façades photographed or individual houses from a small distance may appear smaller or inclined.

This phenomenon known in photography is to be necessarily taken into consideration during the monitoring of industrial manufacturing processes. The position of the registering laser scanner to the monitored surface mostly conditions a perspective distortion that is corrected in the case of SmartRay products by individual calibration based on multiple reference points in the field of vision. As a result, you can also rely on this technology to process images with the standard methods of 2D image processing.
