Here, IвЂ™m going to show you how to merge the two seperate scans using CloudCompare.ДЇirst thing to do is load both models into CloudCompare: IвЂ™ve renamed the meshes once imported into CloudCompare, as you can see on the left. IвЂ™ve called the two models вЂupвЂ™ and вЂdownвЂ™, for conveinience. Both models were made from 100 photos (50 DSLR, 50 Note 8) from my automated setup. When they work, they work really well, but sometimes they can be unreliable.ДЇor this demonstration, IвЂ™ve got two photogrammetry scans of a fossil Trilobite, one of it lying on itвЂ™s lower surface, and one of it resting upside down. Both Agisoft Metashape and AliceVision Meshroom have functions for aligning two sets of photos, but they rely on quite a lot of overlap. In those cases, you can scan both sides separately then merge the meshes.

Or something thatвЂ™s an awkward shape for reliably balancing one way or another. Maybe youвЂ™ve got a large bone or other object that canвЂ™t be moved easily. This is the method my automated photogrammetry set-up relies on вЂ“ the white turntable and white background mean I take photos with the object in multiple orientations, then throw all the photos in Meshroom in one go.Д«ut thatвЂ™s not always possible. With photogrammetry, that might involve what IвЂ™ve seen called the вЂvoidвЂ™ method вЂ“ place your object against a featureless background, so that when you turn it over, the software doesnвЂ™t realise and things the camera has moved instead. Ideally, when you scan an object with laser scanning or photogrammetry, you want to get the whole thing in one go. This post will show you how to align a scan in two or more parts using CloudCompare.
