Capture the data
A linear pattern is projected over an object to form a new high density contoured surface. With this, a sequence of images can then be taken from multiple angles to build a 3D point cloud based on the projected surface.
Triangulation is used to calculate the geometry of the object by measuring the distance between the camera, projector, and the object’s surface. Software brings the data together and builds a digital reconstruction of the object – something that can even be done in real time.
Colours are also integrated between the projected pattern and the camera to avoid disruption to the overall quality of the finished 3D model.
