When getting the data back it is super useful to not only get an OBJ/textures of your model, but also a scene that has the cameras in, along with images corrected for lens distortion. My personal preference is to keep my work somewhat private, so I don't much like the idea of my data being sent off in to the cloud for processing, but I might just be old and jaded. The higher end Autodesk solution (Recap Pro) can do a great job - often stuff looks better from that than Agisoft - plus it supports GoPro (super wide) images now, so if you do photogrametry from drones, that is a plus. Autodesk 123D Catch is fine and free, however it doesn't use full resolution photographs, and will only give you an averagely dense mesh. The #1 rule of photogrametry is that you can never have too many photos.Īs for software - Agisoft Photoscan is great, and honestly quite a steal at the price. Take WAY too many pictures (or think that you are taking way too many pictures). Use a tripod if you have to when taking shots. Shoot in good light and make sure your pictures are correctly exposed. Try to use a high F Stop, get as much in focus as possible. Even if you use a zoom and never touch the zoom dial, it can still move a little. I tend to avoid zoom lenses (Primes have higher quality for the price) - some photogrametry software prefers shots in a project to all be shot with the same camera/lens - a prime (non zoom) lens fixes that.
I personally like to use a 50mm lens on a full frame camera (Canon 5D Mk2). Almost any camera that has a decent sized sensor and a good lens should work fine.
