摘要:
A method for measuring a distance includes modulating the light beam at a first frequency, receiving a second beam by the optical detector to produce a first electrical signal having the first frequency and a first phase; modulating the light beam at a second frequency different than the first frequency; receiving the second beam by the optical detector to produce a second electrical signal having the second frequency and a second. After these steps, the retroreflector is moved while modulating the light beam continuously at the second frequency; and a first distance to the retroreflector is determined based at least in part on a the first and second frequencies and phases.

A three-dimensional (3D) coordinate measurement system includes: a retroreflector; a laser tracker including: a first light source; a second light source; at least one camera proximate the second light source; and a processor responsive to executable instructions which when executed by the processor is operable to determine, in a first instance, that a follow-operator gesture has been given by an operator and in response turn the laser tracker to follow movement of the operator.
摘要:
A method and system are provided for controlling a measurement device remotely through gestures performed by a user. The method includes providing a relationship between a command and a gestures. A gesture is performed by the user with the user's body that corresponds to the user gesture. The gesture performed by the user is detected. A command is determined based at least in part on the detected gesture. Then the command is executed with the laser tracker.

A three-dimensional (3D) coordinate measuring system includes an external projector that projects a pattern of light onto an object and an aerial drone attached to a 3D imaging device, the 3D imaging device and the external projector cooperating to obtain 3D coordinates of the object.
摘要:
A three-dimensional (3D) measuring device includes a cooling fan and an enclosure attached to a projector and a camera. The camera images a pattern of light projected by the projector onto an object to determine 3D coordinates points on the object. A fan draws air through an opening in the front of the enclosure, across a plurality of components in the enclosure and out a second opening in the enclosure.
摘要:
A method for determining 3D coordinates of points on a surface of the object by providing a remote probe having a probe tip and a non-contact 3D measuring device having a projector and camera coupled to a processor, projecting a pattern onto the surface to determine a first set of 3D coordinates of points on the surface, determining susceptibility of the object to multipath interference by projecting and reflecting rays from the measured 3D coordinates of the points, projecting a first light to direct positioning of the remote probe by the user, the first light determined at least in part by the susceptibility to multipath interference, touching the probe tip to the surface at the indicated region, illuminating at least three spots of light on the remote probe, capturing an image of the at least three spots with the camera, and determining 3D coordinates of the probe tip.
