ReconstructMe

ReconstructMe’s usage concept is similar to that of an ordinary video camera – simply move around the object to be modelled in 3D. Scanning with ReconstructMe scales from smaller objects such as human faces up to entire rooms and runs on commodity computer hardware. Read more about its features. Integrate ReconstructMe into your application using our powerful SDK. ReconstructMe’s usage concept is similar to that of an ordinary video camera – simply move around the object to be captured. However, instead of a video stream you get a complete 3d model in real-time. Read about our hardware requirements. Modelling with ReconstructMe scales from smaller objects such as human faces up to entire rooms. ReconstructMe is capable of capturing and processing the color information of the object being scanned, as long as the sensor provides the necessary color stream.
