One of the characteristics of this project seems to be a large number of variables to either tweak or constrain, and a near-limitless number of things to try which are likely to have an effect on the resulting point cloud. This is a list of potentially optimizable variables or options.
Aerial Ecosynth
- Varying altitude
- Downsampling Resolution
- Decimating sequential pictures
- Synthing every other, or every third picture
- Varying the intervalometer at the camera level
- Varying number of cameras
- Varying camera and camera settings for
- low noise
- low motion blur
- sufficient depth of field
- Varying camera lens angle of view
- Varying flight path
- Parallel Transects in a zig-zag pattern
- Overlapping 'Transect Grid' flight path
- Two superimposed grids to accomodate flying limitations
- Multiscale flight
- Flying simple flight transects at 50m, and then flying the same pattern at 100m
- Decimating the 100m data, eliminating 3/4 of pictures to reduce data processing to 125% of original, and maintain overlap decisions
- Fusion of NIR and RGB band pictures
- Removal of NIR-blocking filter on an RGB camera
- Orange filter on NIR-converted camera
- Registration of NIR and RGB point clouds
- Incorporation of flash illumination for constant spectral quality
