I'm currently performing an engineering honours thesis on terrestrial photogrammetry and laser scanning in Archaeology. Both methods will be used to document a single location first and analysis will be performed into which technique is best suited to different styles of documentation.
Geo-referencing and scaling will be performed with reasonably permanent targets (e.g. stick on or glued). The initial area of measurement is quite small (5m x 5m) so I am looking at placing 4-5 geo-referenced targets.
It would be great if i could use targets that would be auto-recognized by most software packages. I have looked for a solution but am coming up empty handed.
Are most targets proprietary and linked to a specific software or is there a open-source style of target recognition?
It would be amazing if i could use the same targets for both laser scanning and photogrammetry. However, I am open to the idea of using two styles of target, one for photogrammetry and the other for laser scanning. For instance, using the photogrammetry targets to accurately scale and georeference the photogrammetry model but then registering the laser scanning targets manually, so there are still points of comparison. It would be great to use the same set of data rather than multiple sets with different targets for each software. This would cut my data management and time down immensely.
In sum, I am asking is there a standard coded target that works across multiple software solutions, and could also be used to manually register a point cloud.
The software I will be experimenting with are:
- 3DF Zephyr
- Agisoft Photoscan
- Leica Cyclone
- AutoDesk ReCap
