The Digital Reverse Camera Projection (DRCP) application is used for onsite photogrammetry. This in-field photogrammetry application allows users to solve for the location and precise perspective were a previous or historical photograph was taken. The historical image is overlaid on the live camera view and the site can then be analyzed for any changes to the site since the photograph was taken. Contemporary photographs can then be taken from the same vantage. The original location of objects can be determined and documented through photographs, video, 3d scanning, or other survey equipment, and used for further analysis such as line-of-sight, sun and shadow, or acoustics.
The application currently offers the following benefits:
• Real-time interactive photogrammetry
• Easily load & toggle photograph overlays
• Replicate vantage of historical photographs
• Determine location of historical evidence
• Live image capture of scene reconstruction
• Fine digital field of view (FoV) adjustment
• Immediate feedback about changes to the site
The DRCP application has been featured in a 2019, peer-reviewed, technical paper by the Society of Automotive Engineers (SAE) titled "The Application of Augmented Reality to Reverse Camera Projection".
