Direct Dimensions’ Part Automated Scanning System (PASS) is designed for high-capacity, automated 3D object scanning. PASS is said to enable continuous 3D digitization of small objects, parts, artifacts and collections.
The semiportable scanner system consists of a tower structure with 16 high-resolution, digital single-lens reflex (DSLR) cameras, integrated lights, custom table and turntable, and a computer controller for operations, metadata and review.
The company says objects placed on the turntable are automatically photographed nearly 400 times from different angles over in two 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 maximum object volume is 16″ × 16” × 16” with accuracy at <1 mm, as low as ±10 microns. The capture time is approximately two minutes with postprocessing time unattended in background approximately seven minutes. The output is an OBJ mesh file + JPG texture file + flat-file metadata table. Additional metadata fields are customizable upon request.
The system system footprint is 9 ft. × 5 ft. × 8 ft. tall, plus room to stage objects. Power requirement is one 15-amp AC outlet. The lighting system contains integral LED light and texture-projectors. The system is suitable for small rooms with normal office lighting. The turntable features an emergency stop and continuous eye-safe lighting, the company says.
