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.

Abstract: A method for measuring 3D coordinates of points on a surface of an object by providing an articulated arm connected to a laser line probe. The laser line probe having a color camera sends color images to a processor, which determines 3D surface coordinates using triangulation. The processor weights each of the colors received from the pixels to enable dark and bright regions of the surface to be measured simultaneously.

Abstract: A handheld three-dimensional (3D) measuring system operates in a target mode and a geometry mode. In the target mode, a target-mode projector projects a first line of light onto an object, and a first illuminator sends light to markers on or near the object. A first camera captures an image of the first line of light and the illuminated markers. In the geometry mode, a geometry-mode projector projects onto the object a first multiplicity of lines, which are captured by the first camera and a second camera. One or more processors determines 3D coordinates in the target mode and the geometry mode.
