Abstract
A portable articulated arm coordinate measuring machine (AACMM) for measuring the coordinates of an object in space and a method of operating the AACMM is provided. The AACMM includes a laser line probe is having a projector and a camera, the projector projecting a line of light, the camera having a lens assembly and a sensor assembly. The sensor assembly having a filter disposed between a photosensitive array and the lens assembly. The filter has a plurality of red, green and blue pixels in a predetermined arrangement. A controller causes the camera to acquire a metrology image and a color image. 3D coordinates of points on a surface are determined based on the metrology image and a color is assigned to the points based on the color image. The exposure time for the color image is adjusted based on an Exposure To The Right or a Mid-gray color model.
