iWitnessPRO-V4 was used to generate a dimensionally accurate and visually stunning 3D reconstruction of a wooden barn, fences, tractor, trailer & surrounding landscape from imagery recorded from a multi-copter UAV flying at 60m above ground, viewing obliquely to the barn over a distance of around 90m, which produced an image scale of 1:2500.

Some 49 images were captured with a 36 megapixel Sony a7R camera, and these were processed fully automatically by iWitnessPRO-V4 in less than 1 hour. The approximate object-space accuracy achieved was 2cm (assessed against surveyed checkpoints), with over 12,000,000 points being generated in the final dense point cloud.
