• Can use both metric and standard, non-metric digital cameras
• Includes camera calibration software for non- metric devices
• Uses ‘fast and easy’ bundle adjustment to link multiple images together and create 3D model
• Can produce 3D data accurate to ½mm at 10m range – targeted points
• Can also produce 3D data from stereo-pairs using only scaled distances
• Calculation and display of distances, cross sections, contour lines and area calculation
• Can digitise line/vector data either from stereo screen or directly onto 3D model
• Generation and display of ortho-images and 3D models
• Basically all the tools required for photogrammetric processing

40. Orientation Results – Y-Parallax
Parallax
“The apparent displacement or difference of orientation of an
object viewed along two different lines of sight”
Check the y-prx values – if any are greater than 1 pixel they may need re-digitising to increase the accuracy of orientation

41. Orientation Results - unsuccessful
If orientation unsuccessful check what Result List states.
May simply be a scaled distance typed in incorrectly, or a badly digitised point which requires remeasuring. Also one of the scale measurements may be incorrect so try removing one and re-running.

Height can be manually set by rotating the mouse wheel – when on the surface, cursor should be over the same point in both left and right image
Speed of height movement can be increased by holding down either the Shift or Ctrl key whilst rotating the mouse wheel

49. Auto correlate On/Off, A+spacebar or middle mouse button
