Review of Bonebed Cartography String Grid Cartography CAD Systems GIS Systems LIDAR

Review of Bonebed Cartography Photogrammetry Excellent accuracy Excellent 3D data representation Time consuming data analysis

Photogrammetry Equipment Digital Camera > 10 megapixel Rugged Remote shooting capability Canon G-10 14.7 megapixel

Photogrammetry Equipment Overhead Rig Crane cam Camera-on-a-stick

Photogrammetry Equipment Photographic Scales Large Vivid Textured Numerous

Photogrammetry Equipment Computers Good processing power Dual core processor at 2.94 GHz per core Large memory Minimum of 6 GB Powerful video card 512 MB of on-board memory Ample disk space 2 GB per section Gaming machines Image Courtesy of Wikimedia

Photogrammetry Equipment Photogrammetry Software ADAM http://www.adamtech.com.au/3dm/Analyst-Mining-Underground.html ≈ $30,000.00 Photosynth http://photosynth.net/ ≈ Free + staff time Geosynth http://www.vexcel.com/geospatial/geosynth/ ≈ $10,000.00 AGISoft http://www.agisoft.ru/products/photoscan/ ≈ $180.00 / $3,500.00

Photogrammetry Equipment Processing software MeshLab http://meshlab.sourceforge.net/ Free MadEdit http://sourceforge.net/projects/madedit/

Photogrammetry Procedures Clean area Dust Eliminate moving objects

Photogrammetry Procedures Place scales Multiple orientations Height scales

Photogrammetry Procedures Taking pictures Bright lighting No flash 2/3 overlap Limit number of pictures

Photogrammetry Procedures Build point-cloud Remove faulty photographs Crop to area under study Wait 3-4 hours

Photogrammetry Procedures Build surface Check for ‘point sprays’ Check for major distortion Crop to desired volume Wait 6-8 hours

Photogrammetry Procedures Build texture Select an appropriate resolution Wait .25-2 hours

Photogrammetry Procedures Export formats WRL For use in MadEdit For use in MeshLab STL For use in rapid prototyping / CAD PDF For general distribution

Photogrammetry Procedures Correct scale Measure in AGI or MeshLab Check for major distortion Select scales to be measured Use Excel to find correction factor X and Y should be the same Z will be slightly different Use MadEdit to correct for errors Repeat
