[QUOTE="MortenVR, post: 99151, member: 18774"] You dont sound harsh at all, no worries. As an example, some of my colleagues are excavating the remnants of a late stoneage/early bronzeage burial mound. As a part of the documentation several surfaces has been recorded via 3D photogrammetry each consisting of 1200-1500 pictures taken with a Nikon dslr camera. These photos are run through Agisoft combined with ground control points resultant in a very accurate model (usually with a deviation of lede than 1,5 centimeters). By using a drone instead of a dslr, some of the finer details will be lost (but on this scale that would not matter much) but the amount of pictures would be greatly reduced. We would still be using Agisoft. By reducing the amount of pictures, we would also reduce the time spent with Agisoft and the amount of data we need to store ( each picture is about 10 MB, so several layers of take up a lot of space) The museum is “owned” by the municipality, and economy is always an issue. So to convince my colleagues and those who pay our salary, that an investment of not only a proper drone, but also training an certification is needed, I considered to buy a spark and by using that, i could prove my point. English is not my first, nor second language, so please ignore the errors. [/QUOTE]
