Patent number: 9594156Abstract: A laser scanner measures a surface of spaces and/or objects and produces a point cloud representing the surface. The laser scanner includes a laser source for producing laser light, a detector for receiving the laser light, and a platform that pivots relative to a stationary base of the laser scanner. The laser light is directed to a particular point on the surface through an outlet point. Laser light scattered at the particular point is received through an inlet point on the platform. A distance to the particular point is determined using laser light scattered and received by the detector. A direction to the particular point is detected using, for example, one or more sensors for determining a pivot position of the platform relative to the base. A parallel kinematic drive pivots the platform relative to the base to scan the laser beam over points of the surface.Type: GrantFiled: July 25, 2012Date of Patent: March 14, 2017Assignee: HEXAGON TECHNOLOGY CENTER GMBHInventors: Bo Pettersson, Bernhard Sprenger, Knut Siercks
