Abstract

Spaced-apart light spots are projected in a light pattern on a target surface lying in a target plane. A range spot is projected at a position on the target surface to find a target distance to the target surface. An image of the target surface, light pattern, and range spot is captured along an imaging axis that is perpendicular to an imager plane of an imager. A controller determines an angular relationship between the imager and target planes based on the light pattern in the captured image, determines a scale relationship between the target surface and the imager based on the position of the range spot in the captured image, displays a compensated image of the target surface that is corrected in tilt by the angular relationship and in scale by the scale relationship, and determines dimensions of the target surface based on dimensions of the displayed compensated image.
