摘要： 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.

摘要： 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.
