Abstract:
1. A structured light sensor system for measuring contour of a surface, the system comprising: a projection system configured to project onto the surface either (i) a point of light, (ii) a first plurality of points of light forming a line of light, or (iii) a second plurality of points of light forming a plurality of lines of light; an imaging system configured to selectively capture an image of the surface, wherein the image of the surface is based on light reflected off the surface; and a control module configured to coordinate control of both the projection system and the imaging system to operate the structured light sensor system in each of: (i) a point mode, during which the projection system projects the point of light during a first period and the imaging system is on for the first period, (ii) a line mode, wherein the projection system projects the first plurality of points of light during a second period and the imaging system is on for the second period, and (iii) an area mode, wherein the projection system projects the second plurality of points of light during a third period and the imaging system is on for the third period.
