  • Publication number: 20240095944
    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.

  • Patent number: 11930155
    Abstract: A 3D measuring system includes a first projector that projects a first line onto an object at a first wavelength, a second projector that projects a second line onto the object at a second wavelength, a first illuminator that emits a third light onto some markers, a second illuminator that emits a fourth light onto some markers, a first camera having a first lens and a first image sensor, a second camera having a second lens and a second image sensor, the first lens operable to pass the first wavelength, block the second wavelength, and pass the third light to a first image sensor, the second lens operable to pass the second wavelength, block the first wavelength, and pass the fourth light. The system further includes one or more processors operable to determine 3D coordinates based on images captured by the first image sensor and the second image sensor.

  • Patent number: 11908162
    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.

  • Publication number: 20220316857
    Abstract: A system includes a first light source that emits a beam of light; an electrical modulator that imparts a time-varying modulation on the beam of light; a beam- shaping system that shapes the beam of light and projects the shaped beam of light onto an object; an image sensor that captures the beam of light reflected from the object; and processors that determine three-dimensional (3D) coordinates of points on the object.

  • Patent number: 10699442
    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.
