Page 77 - 3DF Zephyr

The "Export" (3) subsection allows to export:  World file (3DF Zephyr Pro and 3DF Zephyr Aerial)  Autocad script (3DF Zephyr Aerial) - exports a scr file that will automatically load the orthomosaic within Autocad, with the correct scale settings set in Zephyr  .KML file (3DF Zephyr Aerial) The Output subsection (4) allows to define the width and height of the output file (thus controlling the ground sample distance) The Advanced subsection (5) allows to control the color generation mode for each single pixel. This is system is very similar to the texture generation system. We advise to leave the color balance on with 1 camera per pixel. If you wish, you may however use more cameras for a different color weight. If this happen, you may choose between a fusion algorithm: Blending - will weight the color source depending on the view angle and the distance. Although it's robust to lighting changes, the mean won't keep high frequencies. Multiband - will use the mean to to compute low frequencies and the best images to compute the high frequencies. This is usually a better choice than blending because while it is still robust to lighting changes (usually just a little worse than blending) by preserving the high frequencies the resulting image will be more in focus and sharp. Generate Orthophoto: To proceed with the orhtophoto generation you must have generated a mesh first.
