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.

Photosensor processing for improved line scanner performance

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.

Handheld scanner for measuring three-dimensional coordinates

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.
