Capturing high-quality 3D models of small objects presents unique challenges, but with Polycam's Object Mode and the proper techniques, you can achieve professional-grade results. This guide will walk you through the process of creating detailed scans of small objects.
Optimal Scanning Environment Setup
The ideal setup for scanning a smaller object includes:
Isolation and Background: Position your object in a clutter-free area against a plain, matte background. Using a box will help isolate the object, allowing the system to stitch the image together correctly.
Lighting Considerations: Implement even, diffused lighting to eliminate harsh shadows that can interfere with the quality of the capture.
Surface Stability: Place your object on a stable, non-reflective surface to prevent movement during scanning and to avoid light reflections that can distort the model.
Technical Setup in Polycam
Before beginning your scan, optimize your device settings:
1. Mode Selection: Launch Polycam and activate Object Mode.
2. Camera Optimization: For iOS devices, you can use the Macro Camera option to capture fine details.
3. Focus Adjustment: If you encounter focusing issues, double-tap on the object to auto-focus and prevent blurry images from being taken.
How to Scan
You can begin with a complete 360-degree pass around the object at mid-height. This initial loop establishes the core structure of your 3D model.
After completing the loop, you can add additional frames from various perspectives—lower angles, higher positions, and top-down views. You want each image to have a 70% overlap.
Dedicate extra frames to corners, curved surfaces, and textured regions. Capturing these features from multiple angles helps to construct the model accurately.
