PASS - Part Automatic Scanning System

Direct Dimensions, Inc. has designed and developed PASS: Part Automated Scanning System for high- capacity automated 3D scanning of objects. PASS allows continuous 3D digitization of small objects, parts, artifacts, and collections. The semi-portable scanner system consists of a tower structure with (16) high-resolution DSLR cameras, integrated lights, a custom table and turntable, and a computer controller for operations, metadata, and review. Objects placed on the turntable are automatically photographed nearly 400 times from different angles over in 2 minutes. The 2D images are then automatically converted into a dimensionally accurate textured 3D mesh model using a process known as photogrammetry. The 3D digital models and object metadata can be uploaded to a database for cataloguing and visualization interactively in 3D. The major system components are: - Camera tower structure with (16) high-resolution DSLR cameras - Integrated light system - Scanning table with turntable and backdrop - Operator workstation computer - Data server - High-speed processing computer Functional Specifications: • Maximum object volume: 16” x 16” x 16” • Accuracy: <1 mm, as low as +/- 10 microns • Capture time: approx. 2 minutes • Post-Processing time (unattended, in background): approx. 7 minutes • Output: OBJ mesh file + JPG texture file + flat-file metadata table • Additional metadata fields customizable upon request Physical Specifications: • System Footprint: 9 ft x 5 ft x 8 ft tall, plus room to stage objects • Power requirements: One 15-amp AC outlet • Lighting: System contains integral LED light and texture-projectors • Environment: Suitable in small room with normal office lighting • Safety: Turntable emergency-stop; continuous eye-safe lighting Object Preparation: • Object limitations: Should be rigid and opaque; and fit in volume • Object prep: Some shiny or glossy objects may need to be treated
