Performing data collection based on internal raw observables using a mobile data collection platform
Patent number: 9538336Abstract: An image that includes a point of interest is captured using an image capturing device that is part of the mobile data collection platform. Raw observables are obtained from a GNSS chipset that is internal to the mobile data collection platform. A position fix of the mobile data collection platform is determined based on the raw observables where the position fix defines a location of an antenna. A location of an entrance pupil is calculated as an offset of the location of the antenna. Orientation information comprising a tilt angle and an azimuth angle is determined. The position fix and the orientation information are associated with a three dimensional location that the mobile data collection platform is at when the image was captured. Scale information is captured. The image, the position fix, the scale information, and the orientation information are stored in hardware memory of the mobile data collection platform.Type: GrantFiled: October 15, 2014Date of Patent: January 3, 2017Assignee: Trimble Inc.Inventors: Richard Rudow, Venkateswaran Kasirajan, Robert Wold, Nicholas C.

Patent number: 9488736Abstract: A method of improving position determination of a device using locally measured movement. A first position fix of a Global Navigation Satellite System (GNSS) receiver system of a device is accessed. A second position fix of the GNSS receiver system is accessed at a time subsequent to the first position fix. Locally measured device movement information is obtained from at least one sensor, that is in a known physical relationship to the device, for a time period after the first position fix and no later than the second position fix, wherein the at least one sensor comprises an image capture device. The quality of measurement of the second position fix is improved by disciplining the second position fix based on the locally measured device movement information.Type: GrantFiled: May 2, 2014Date of Patent: November 8, 2016Assignee: Trimble Navigation LimitedInventors: Shawn D.

Patent number: 9324003Abstract: A method for matching a region on an object of interest with a geolocation in a coordinate system is disclosed. In one embodiment, an image of a region on an object of interest is captured on an image capture device. The image is processed to detect a located feature using a feature detection algorithm. Further processing of the located feature is performed to derive a first feature descriptor using a feature descriptor extraction algorithm. The feature descriptor is stored in a memory. A database of feature descriptors having geolocation information associated with the feature descriptors is searched for a match to the first feature descriptor. The geolocation information is then made available for access.Type: GrantFiled: March 14, 2013Date of Patent: April 26, 2016Assignee: Trimble Navigation LimitedInventors: Peter G. France, Shawn D.
