Abstract

An articulated arm coordinate measuring machine includes a laser line probe. The laser line probe includes a camera that can acquire metrology data and color data. A laser line probe is coupled to a probe end of an articulated arm. The laser line probe having a projector and a camera, the projector being operable to project a line of light at one or more predetermined wavelengths, the camera having a lens assembly optically coupled to a sensor assembly. The sensor assembly has a photosensitive array and a filter disposed between the photosensitive array and the lens assembly. The filter includes a plurality of red, green and blue pixels in a predetermined arrangement. A controller is coupled to the laser line probe and causes the camera to acquire a metrology image and a color image. The controller assigns a color to the three-dimensional coordinate points based on the color image.
