Photogrammetry is measuring from photographs. There are a lot of techniques and usages. This technique uses software which incorporates “Structure from Motion” for searching the same feature points in every photograph and then figures out where they are placed in a 3D space. After the feature points are placed, the “Multi-View Stereo” technique is used to extensively compare neighboring photographs for more feature points. When the dense feature point cloud is made, the 3D mesh can be generated and high quality texture from photographs can be projected.
3D scanners can be very expensive but can produce constant highly precise geometry using structured light but usually without texture. They are used mainly in science and medical fields, all of which are close distance scans. Photogrammetry on the other hand can be cheap and easy to carry around but the main value is the highly detailed texture which is a very important asset creation method for computer games and movies and especially for interactive product presentation for commercial necessities. Photogrammetry is very popular among archaeologists and geologists, because it is possible to scan from a far distance. It is also possible to combine laser scanning and photogrammetry.
Portraits, body parts, emotions, products or historical artifacts. It is possible to get a highly dense and detailed texture model and an optimized version for use in augmented and virtual reality.
Yes! But object movement will be limited to a set area. For example, you could capture a dog who is constantly moving, but with our solution it doesn’t matter if it moves, we can catch any moment and make 3D model of him.
