BOSTON, 1 Aug 2006: Z Corporation on August 1 unveiled handheld, self-positioning 3D scanner that can digitize 3D surfaces in real time at SIGGRAPH 2006, the computer graphics conference. The ZScanner 700 is the part-referenced 3D scanner, orienting itself to the target object rather than an external device. As a result, it is also the first 3D scanner that allows the user to move the target object during scanning, and it is the first 3D scanner to display a real-time on-screen image of the surface being scanned.
These capabilities plus handheld portability make the ZScanner 700 suited for scanning complex surfaces and hard-to-reach areas like car interiors. It captures data in one continuous scan rather than in numerous shots from fixed positions. ZScan software, included with the scanner, automatically produces an .stl file for import into a 3D CAD software package or output to a 3D printer.
To scan, the user picks up the ZScanner 700 handheld unit and “paints” the object with a projected laser crosshair. The surface is recorded by the scanner’s dual cameras. ZScan software generates a polygon mesh of the surface on the computer screen in real time. The ZScanner 700 is accurate within +/- 0.05mm and detects changes in surface height down to 0.1mm.
