Wearable Photogrammetry - What to Wear for Work #COMIT2017

  1. 1. The Wearables are Coming – Camera Tech to Wear for Work
  2. 2. =
  3. 3. • Cheaper/ less invasive • Non Invasive/ disruptive to daily tasks • Fully automated • Not restricted by legislation (apart from H&S) • Cheaper alternative to Drone technology • Easier access…. “Can reach the parts that other Drones cannot reach “
  4. 4. MOBILE DEVICES ContextCapture On-Premise ProjectWise ContextShare Cloud Cloud WEARABLES DRONES
  5. 5. Context Capture Automatic generation high-resolution 3D Reality Models from laser scanner and photos taken with: - a digital camera - a smartphone - mounted on a drone - or on an aircraft with a dedicated multi-directional acquisition system.
  6. 6. Brief To integrate reality capture technology with a routine activity (i.e. Site Inspection) on site, in order to create a “self-regulating” data capture process. And apply reality modelling to anything from site safety, inspection to visualisation, training, etc.
  7. 7. First Tests
  8. 8. Test 1 2 cameras: One on the helmet, another on the chest
  9. 9. Test 2 2 cameras: Both on the helmet
  10. 10. Test 3 Real World Conditions – BAM Site • 4716 photos • 15 minutes
  11. 11. Test 3 Video vs Photo: Video – Test 1 Video – Test 2 Photo – Test 3 2 Cameras: Front and Back Frames sliced to ¼ sec Frames sliced to ¼ sec Picture every 2 sec 2.7 K video, 60 fps 1080p, 120 fps 10 MPix Resolution
  12. 12. Test 1 – 2.7 K Video – 60 fps
  13. 13. Test 2 – 1080 p Video – 120 fps
  14. 14. Test 3 – Photo Data
  15. 15. Further investigations Crane Project
  16. 16. Project • Off-the-Shelf GoPro Omni Rig • Mounted on A crane Hook In Real Construction site • Data Processing with ContextCapture
  17. 17. Project problem • Crane disassembly in narrow street is a complicated process…
  18. 18. Project Problem One needs to make sure massive parts fit through narrow streets when assembled and disassembled…
  19. 19. Project Problem • All planning is done through 2D pdf’s and images…
  20. 20. Go Pro Omni Crane Mount Test
  21. 21. Context Capture
  22. 22. Et voilà
  23. 23. Findings • Bespoke camera system could be created • GPS/IMU Needed • Automatic data transfer and processing straight from the camera • Adjustable camera orientations would be good to have
  24. 24. Partners
  25. 25. Research @ Centre for Systems Engineering and Innovation, Imperial College London The current research proposes an integrated cloud-based framework to enable efficient construction progress monitoring by creating an automated real-time bidirectional flow of information between the construction site and planning office. The research is done at Centre for Systems Engineering and Innovation and is funded through Skempton scholarship and co sponsored by Bentley Systems.
  26. 26. Proposed Framework http://www.scottishconstructio nnow.com/18894/consortium- visualises-augmented-reality- future-for-construction- industry/
  27. 27. Early Output on AR visualization (A) (B)
  28. 28. Panel Session
  29. 29. Thankyou Please contact If you are: • interested in Joining this project or the Drone 11 project • able to offer up some sites that we may attend to run trials.. then please get in touch… • wanting to propose a project
