3D Photogrammetry Scanner with DSLR

This is a DIY 3D scanner built for photogrammetry, using a DSLR camera mounted on a stable, motorized rig. Ideal for scanning figures, props, or small objects for modeling or 3D printing.

Features:

• High-resolution image capture using a DSLR (tested with Canon 500D)
• Object rotation and camera movement via 2 NEMA 17 stepper motors
• DSLR camera triggering fully automated using Python and digiCamControl
• Compact and rigid M8 rod frame for accurate image alignment
• Smooth motion with linear rails, bearings, and stepper control

Electronics & Control:

• Microcontroller: Arduino Nano
• Motor Drivers: 2x L298N
• Motors: 2x NEMA 17 Stepper Motors
• Button: Mechanical keyboard key switch (manual scan start)
• Software:

  • Python Script for automated capture control

  • digiCamControl for DSLR shutter triggering via USB

Mechanical Parts:

• 2x 40cm M8 Rods
• 2x 50cm M8 Rods
• 2x 60cm M8 Rods
• 1x 50cm M8 Threaded Rod
• 1x M8 Nut
• 1x 5x8mm Aluminum Alloy Coupling
• 4x 608ZZ Bearings
• 2x SC8UU Linear Bearings
• 1x DSLR Hotshoe to 1/4-Inch Male Adapter
• 8x M4x10 Screws
• 10x M3x8 Screws
• 2x M3 Nuts

How It Works:

1. Start Scan: Press the keyboard-style key switch.
2. Stepper Control: Arduino rotates the platform or camera arm.
3. Image Capture: Python script communicates with digiCamControl to trigger the DSLR.
4. Result: A full 360° set of photos ready for photogrammetry software (like Meshroom or Metashape).

Ideal For:

• Makers & hobbyists scanning miniatures or props
• DIY digitization of real-world objects
• Anyone wanting an affordable, customizable photogrammetry setup
