Abstract: A method includes providing a measuring device having a projector, a camera with a photosensitive array, and at least one processor, projecting with the projector a line of light onto an object, capturing with the camera an image of the projected line of light on the object within a window subregion of the photosensitive array, and calculating with the at least one processor three-dimensional (3D) coordinates of points on the object based at least in part on the projected line of light and on the captured image.

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.

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.
