Photogrammetric Drone Mapping

These two drone missions were flown consecutively as part of the natural stone restoration of the Braunschweigkolleg. Mission A was a double-grid overhead mission to create a quick model. Mission B was calculated based on the quick model, thus enablling the drone to follow the real building geometry. This technique eliminated blind spots and allows for a precision of up t 3mm/px in Model B. [the web version are compressed]
