Publication number: 20240093988Abstract: A method of measuring a structure includes acquiring azimuth and tilt readings at a first location and second location. Images of the structure are also acquired from the first and second location. The respective distances from the first and second locations to a first and second point on the structure are measured. A scale is established from two positions of the structure depicted in the first or second image of the structure. The distance between the first and second points on the structure is found using the established scale. This distance is used with the azimuth and tilt readings and measured distances from the first and second location to build an epipolar model of the structure. The structure may be a utility pole. Also disclosed are methods of assisting photogrammetric measurements and estimating the class of a utility pole, and methods of determining the compliance status of a utility pole.Type: ApplicationFiled: November 21, 2023Publication date: March 21, 2024Applicant: IKEGPS Group LimitedInventors: Jeremy James GOLD, Leon Mathieu LAMMERS VAN TOORENBURG

Patent number: 9952316Abstract: A portable instrument or apparatus includes a portable device and a rangefinder module. The rangefinder module can be attached to the portable device, which may be any suitable smartphone, tablet or other consumer electronics device having a camera. By suitable alignment of the rangefinder and camera, the device is capable of capturing accurate data over significant ranges, including for example an image of a target together with position information concerning the target. A folded optical arrangement reduces the volume and thickness of the rangefinder module.Type: GrantFiled: January 9, 2015Date of Patent: April 24, 2018Assignee: IKEGPS Group LimitedInventors: Leon Mathieu Lammers Van Toorenburg, Donald Stewart Mawson, Allan David Beach

Publication number: 20160349602Abstract: The invention relates to a mounting mechanism for mounting an auxiliary device, such as a rangefinder, to a mobile device. The mounting mechanism includes an interface surface with formations to engage with a surface of the mobile device to maintain a desired orientation between the mobile device and the auxiliary device. The mounting mechanism also includes two or more arms which may be moved synchronously towards each other to clamp a mobile device engaged with the interface surface so as to maintain the mobile device centralised with respect to the interface surface.Type: ApplicationFiled: May 31, 2016Publication date: December 1, 2016Inventors: Leon Mathieu LAMMERS VAN TOORENBURG, David Neil LOVEGROVE, Carl Benjamin MENARY, Ross Hughan DAWSON, Oliver Charles Graham JACKSON-HILL

Publication number: 20150317070Abstract: A mobile handheld instrument having a camera, display, user interface, spatial sensors and inertial measurement unit. Upon user selection of an image region within a captured image a processor may determine an orientation of a surface within the image and the region is forced into alignment with the determined orientation of the surface. The processor may also overlay a plurality of markers on a displayed camera feed, each marker being overlaid at a target position for which spatial sensors have already captured data. A user may also select target categories and captured data sets obtained by spatial sensors and associated with the selected target categories. Measurements captured for target points may be overlaid on the displayed camera feed. The determined measurement data may be updated based on a user instruction to alter the set of target points.Type: ApplicationFiled: April 10, 2015Publication date: November 5, 2015Inventors: Leon Mathieu LAMMERS VAN TOORENBURG, Jeremy James GOLD
