This is an open access article under the CC BY license (http://creativecommons.org/licenses/by-nc-nd/4.0/). abstract: When using any optical measurement system one important factor to consider is the placement of the sensors in relation to the work piece being measured. When making decisions on sensor placement compromises are necessary in selecting the best placement based on the shape and size of the object of interest and the desired resolution and accuracy. One such compromise is in the distance the sensors are placed from the measurement surface, where a smaller distance gives a higher spatial resolution and local accuracy and a greater distance reduces the number of measurements necessary to cover a large area reducing the build-up of errors between measurements and increasing global accuracy. This paper proposes a photogrammetric approach whereby a number of sensors on a continuously flexible mobile platform are used to obtain local measurements while the position of the sensors is determined by a 6DoF tracking solution and the results combined to give a single set of measurement data within a continuous global coordinate system. The ability of this approach to achieve both high accuracy measurement and give results over a large volume is then tested and areas of weakness to be improved upon are identified date: 2016-06-15 date_type: published publisher: International Society for Photogrammetry and Remote Sensing official_url: http://dx.doi.org/10.5194/isprsarchives-XLI-B5-123-2016 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1143900 doi: 10.5194/isprsarchives-XLI-B5-123-2016 lyricists_name: Robson, Stuart lyricists_name: Sargeant, Ben lyricists_id: SROBS78 lyricists_id: SARGE94 actors_name: Bracey, Alan actors_id: ABBRA90 actors_role: owner full_text_status: public series: The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, ISPRS Congress publication: International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences volume: 23 place_of_pub: Prague, Czech Republic pagerange: 123-129 event_title: The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XLI-B5, 2016 XXIII ISPRS Congress event_location: Prague, Czech Republic event_dates: 12 July 2016 - 19 September 2016 institution: XXIII ISPRS Congress book_title: Proceedings of the International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XLI-B5, 2016 XXIII ISPRS Congress citation: Sargeant, B; Robson, S; Szigeti, E; Richardson, P; El-Nounu, A; Rafla, M; (2016) A method to achieve large volume, high accuracy photogrammetric measurements through the use of an actively deformable sensor mounting platform.
