THREE-DIMENSIONAL MEASUREMENT DEVICE HAVING THREE-DIMENSIONAL OVERVIEW CAMERA

摘要

A device is provided that includes a housing and a first motor. The first motor rotates about a first axis. A second motor is coupled to rotate the housing, the second motor rotating about a second axis. A device frame of reference is defined by the first and second axis. A mirror is rotated about the first axis by the first motor. A first and second angle measuring devices measure a first and second angle of rotation. A 3D time-of-flight camera is arranged within the housing coaxially with the first axis. The camera acquires an image of an object reflected from the mirror. A processor determines at least one first 3D coordinate of at least one point on the object, the first 3D coordinate based at least in part on the image acquired by the camera, the first angle of rotation, and the second angle of rotation.
