Press Release Summary:

  • Comes with camera tower structure with (16) high-resolution DSLR cameras
  • Accuracy <1 mm, as low as +/- 10 microns
  • Allows continuous 3D digitization of small objects, parts, artifacts and collections

Original Press Release:

PASS: Part Automated Scanning System for High-Capacity Automated 3D Scanning of Objects

System Description

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

System Workflow:

Steps can be performed asynchronously to optimize workflow

  • Pretreat object (if needed)
  • Stage object on support pegs & fixturing
  • Enter object metadata
  • Scan object (2 min)
  • Process images into 3D model (automatic)
  • Inspect processed models
  • Transfer models to catalogue or other database
