HOME MADE 3D SCANNER



This home made 3D scanner uses a webcam, a laser line, a calibration backdrop and DAVID laserscanner software to create accurate and detailed 3D scans. The system must be calibrated first with no model present. Once this has been done the model can be placed in front of the backdrop and the laser line passed over its surface. The camera is able to read the distortions of the laser line as it passes over the surface and DAVID converts this information into a 3D mesh. Multiple scans can be made from different angles, which are then automatically aligned and fused by DAVID. Meshes can be exported in multiple formats, in this case as .obj for further editing in Rhino and rendering with VRay.
