Processor adjusts second collection of points relative to first collection of points based at least in part on first and second translation values and first rotation value. Processor identifies a correspondence among registration targets in first and second collection of 3D coordinates, and uses this correspondence to further adjust the relative position and orientation of first and second collection of 3D coordinates. | 2015-06-11 |
20150160348 | INTERMEDIATE TWO-DIMENSIONAL SCANNING WITH A THREE-DIMENSIONAL SCANNER TO SPEED REGISTRATION - A method for measuring and registering 3D coordinates has a 3D scanner measure a first collection of 3D coordinates of points from a first registration position. The 3D scanner collects 2D scan sets as 3D measuring device moves from first to second registration positions. A processor determines first and second translation values and a first rotation value based on collected 2D scan sets. 3D scanner measures a second collection of 3D coordinates of points from second registration position. Processor adjusts the second collection of points relative to first collection of points based at least in part on first and second translation values and first rotation value. Processor identifies a correspondence among registration targets in first and second collection of 3D coordinates, and uses this correspondence to further adjust the relative position and orientation of first and second collection of 3D coordinates. | 2015-06-11 |
20150160349 | Assisted Positioning Method and Apparatus - An assisted positioning method and apparatus are provided. A user equipment runs the WINDOWS 8 system, the user equipment is connected to a global positioning system (GPS) device having an assisted global positioning system (A-GPS) function, and the assisted positioning method includes detecting, by the user equipment, that the GPS device enables a GPS function; sending, by the user equipment, an A-GPS indication message to the GPS device, where the A-GPS indication message is used to instruct the GPS device to enable the A-GPS function; receiving, by the user equipment, positioning information from the GPS device, where the positioning information is obtained by the GPS device by using the GPS function and the A-GPS function. | 2015-06-11 |
