Scan small to medium-sized objects with your phone (or camera) to generate a complete, editable 3DGS model. Follow the steps below for better results.

Before You Start

1. Device Check

• A smartphone.

• High-resolution camera can be used for higher quality results.

2. Object & Environment Requirements

• The object should have sufficient texture or feature points (e.g.rocks, wooden items)

• Avoid textureless surfaces; for reflective or transparent objects, add surface texture to improve results

• Place the object on a stable surface

• Leave at least 1–1.5 meters of space around the object for full walk-around capture

• Use a clean background with good contrast from the object

• Ensure even lighting; avoid harsh shadows

• Set the center point on the main solid part of the object

How to Capture

1. Capture Modes

2. Capture Distance

3. Capture Path

To fully capture the object and its details, follow this sequence:

1. Spiral Orbit

   • Top ring: circle slightly above the object

   • Middle ring: circle at the object’s mid-level

   • Bottom ring: circle slightly below the object

   • If using photos instead of video: Maintain 70–75% overlap between consecutive images

2. Close-up Shots

   • Capture surface textures, carvings, and complex areas up close

   • Take the same detail from slightly different angles

   • Close-ups don’t need full coverage, but overlap should still be ≥70%

Capture Tips

• Hold the device with both hands for stability

• Move slowly; avoid sudden turns

• Capture complex areas from multiple angles

• For reflective or transparent objects, lightly apply chalk spray or coating to add texture

• Do not move the object during capture

Quality Requirements

Image Count & Overlap

• Minimum: 20 images; for complex objects, 50–60 recommended

• Ensure ≥70–75% overlap between adjacent images

Video Mode

• Continuous recording is supported; the system will extract keyframes automatically

• Move slowly and smoothly around the object

• Avoid rapid motion or abrupt direction changes

Common Issues & Optimization

Common Issues

• Moving too fast → Motion blur

• Uneven lighting → Loss of detail

• Missing angles → Incomplete model

• Insufficient close-ups → Poor surface detail

Best Practices

• Use even lighting and a clean background

• Keep your hands steady and move slowly

• Capture the top, bottom, and hidden areas

• Use multiple angles to capture textures and curved surfaces

After Capture

Once you’ve finished capturing:

• Review images and delete blurry or poorly exposed ones

• Upload to the Aholo app or website to generate your 3D model

• Wait for processing to complete

• Enter the editor to crop, annotate, or measure

• Export a video or share via link
