Introduction Has digitalizing software that enables a user to select specific points on a target object. Employs laser-beam light sectioning technology to scan work pieces. The laser beam is scanned using a high-precision galvanometric mirror, and 640 × 480 individual points can be measured per scan. Can also be used to acquire color image data, by using a rotating filter.

Specifications Scan range (depth of field) 0.6 to 2.5m (2m for WIDE lens) Autofocus Image surface AF (contrast method); active AF Optimal 3D measurement range 0.6 to 1.2m Number of output pixels 3D data: 307,000 (FINE mode), 76,800 (FAST mode) Color data: 640 × 480 × 24 bits color depth Recording medium Compact flash memory card (128MB) Data file size Total 3D data and color data capacity: 1.6MB (FAST mode) per data, 3.6MB (FINE mode) per data ucts/3d/non-contact/vivid910/specifications.html

Comparison

Benefits It is portable Fast Scan time of 0.3 seconds Easy To Use: The point-and-shoot simplicity of auto focus and auto exposure enables anyone to get expert results Versatile: can capture scan areas from 36X27 up to 90X120 cm The subject can be located from 0.6 to 2.0 meters form the scanner. Color Texture Maps: capture texture map images with zero parallax. Utility Software Features: include Minolta’s own polygon editing software suite

Applications UNC Charlotte Machine vision lab acquires a new vivid 910. Used for kayak design by Watermark. Images used in FRGC for 3D Images

Conclusion VIVID In a Class by Itself The new leader in: Speed - scans in less than one second (Fast Mode) Precision - over 300,000 points with range resolution to " (Fine Mode) Simplicity - point and shoot simplicity for consistently excellent results Flexibility - only Konica Minolta offers interchangeable lenses for variable scanning volumes Value - Konica Minolta sets a new price / performance threshold

Commentary The Vivid 910 scanner from Konica Minolta [16] uses a single camera and laser stripe, and acquires 3D data using triangulation. This scanner is not designed specifically for faces as the subject must remain motionless during that time or a poor scan will result. There are three different zoom lenses available and an automatic focus system that allows scanning at a wide variety of distances from the camera (there is a tradeoff between image resolution and standoff) It is somewhat sensitive to lighting conditions, but generally operates well indoors away from sunlight. Hence, It’s an excellent accuracy device, but can improve more based on its cost of $40,000.
