Konica Minolta, the world's largest manufacturer of 3D non-contact digitizing instruments, gives you two 3D scanners with the simplicity of a point and shoot camera that scans 307,000 points in less than a second!
3D Digitiser for high accuracy measurements The newly developed VI-9i uses a new hardware design and an improved measurement algorithm to provide 4 times the measurement accuracy of our previous models (to 50µm), enabling 3D measurement of automobile parts and other objects formed by casting, pressing, molding, etc. The VI-9i can be used for reverse engineering to reflect the shape and dimension data of mock-ups or prototypes in design drawings, or checking part shape, checking molds, inspecting quality, etc. in prototype-production or mass-production processes. In addition, Easy Align Tool II, a 3D data merge tool exclusively for the VI-9i which uses photogrammetric technology, is also being introduced as an optional accessory. With this tool, relatively large parts such as doors, bumpers, interior panels, etc. for which merging of measurement data was difficult with previous instruments, can be rapidly measured and the data merged with high accuracy. Konica Minolta supports complicance with ISO 9000. Manufacturers using the VI-9i for QC applications can receive test report of the accuracy of each 9i, traceable to national standard.
3D Digitiser for types of rapid scanning The Konica Minolta VI-910 is an innovation in 3D Digitizing for both Product Design and Manufacturing. A non-contact 3D digitizer, offering fast, precise capture of 3D shape. This is ideal for applications in both product design and production.The designers find VI-910 invaluable for Reverse Engineering or creating CAD data from physical models and design mock-ups.Production personnel use VI-910 for Inspection and computer-aided dimensional testing. What's more, VI-910 improves concurrent engineering by inexpensively making 3D data available throughout the company.
Typical applications:-
How they work, simply:- Basically you position the unit in front of your object, usually using a tripod or fixing platform, select the correct lens which allows you to be as close as 600mm and as far away as 2.5 meters where you can caputure 1 sq/M of detail at a time. Now check a couple of settings and shoot. Just like using a professional digitial photgraphic camera. The 3D data with image is about 1.6Mb and can be stored on a memory flash card or transfered to your PC via the SCSI II interface. Konica Minolta software is included to assemble your scan data from multiple shots, then export in industry standard common formats. Polygon: DXF, STL, Wavefront, Softimage, VRML 2.0, MGF and ASCII Point groups.
How they work, technical detail:- The Konica Minolta uses laser triangulation. The object is scanned by a plane of laser light coming from the scanners source aperture. The plane of light is swept across the field of view by a mirror, rotated by a precise galvanometer. This laser light is reflected from the surface of the scanned object. Each scan line is observed by a single frame, captured by the CCD camera. The contour of the surface is derived from the shape of the image of each reflected scan line. The entire area is captured in less than 2.5 seconds and the surface shape is converted to a lattice of over 300,000 vertices (connected points). The Konica Minolta scanner gives you more than a point cloud; a polygonal-mesh is created with all connectivity information retained,thereby eliminating geometric ambiguities and improving detail capture. A brilliant (24-bit) color image is captured at the same time by the same CCD. Unlike other scanners, this system has no parallax error, its "spot - on"!
