摘要： An apparatus and method for calibrating a distance meter using a double-pass configuration based on reflection off an intermediate retroreflector. The system includes a first distance meter operable to send a first beam light in a first path that intercepts a first retroreflector and a second retroreflector, to receive the first beam of light after reflection from the first retroreflector and the second retroreflector, and to measure a first distance traveled by the first beam of light, the first retroreflector being located at a first position. The system further includes a second distance meter operable to send a second beam of light in a second path that intercepts the first retroreflector, to receive the second beam of light after reflection from the first retroreflector, and to measure a second distance traveled by the second beam of light.

摘要： A method uses a two-dimensional (2D) camera in two different positions to provide first and second 2D images having three common cardinal points. It further uses a three-dimensional (3D) measuring device to measure two 3D coordinates. The first and second 2D images and the two 3D coordinates are combined to obtain a scaled 3D image.

摘要： A method for verifying performance of a light projector includes establishing a reference artifact that include reflective makers and an interior edge line, determining with a laser-tracker-based three-dimensional (3D) measuring system 3D coordinates of the reflective targets and the interior edge line, determining with the light projector angles to the reflective markers with the light projector, and projecting with the light projector a pattern of light onto the interior edge line.

摘要： A noncontact optical three-dimensional measuring device that includes a first projector, a first camera, and a second camera; a processor electrically coupled to the first projector, the first camera and the second camera; and computer readable media which, when executed by the processor, causes the first digital signal to be collected at a first time and the second digital signal to be collected at a second time different than the first time and determines three-dimensional coordinates of a first point on the surface based at least in part on the first signal and the first distance and determines three-dimensional coordinates of a second point on the surface based at least in part on the second signal.

摘要： A three-dimensional (3D) coordinate measuring system is provided. The system includes an aerial measuring device that has an aerial drone and a 3D measurement device. The 3D measurement device being rotatably attached to the aerial drone, the aerial drone is movable from a first position to a stationary second position. The 3D measurement device being configured to optically measure points on the surface of an object. The system further includes one or more processors configured to execute nontransitory computer readable instructions. The computer readable instructions comprise: moving the aerial measuring device from the first position; landing the aerial measuring device at the second position; rotating the 3D measurement device to optically measure a first object point; and determining a first 3D coordinates of the first object point with the 3D measuring device.

摘要： A dimensional measuring device includes an overview camera and a triangulation scanner. A six-DOF tracking device tracks the dimensional measuring device as the triangulation scanner measures three-dimensional (3D) coordinates on an exterior of the object. Cardinal points identified by the overview camera are used to register in a common frame of reference 3D coordinates measured by the triangulation scanner on the interior and exterior of the object.
