Photo checkpoints & route planning

Use reference objects to create photo checkpoints

MAVO 3D has a neat optimization technology that helps align point clouds correctly after scanning. To get the best results with this "Loop Closure" technology, here some tips for 3D scanning with MAVO 3D.

It requires a bit of practice, but you’ll get the hang of it soon.

Pre-requisite

To access all optimization methods after scanning, enable RAW data capture at the start of the scan. With RAW data on, MAVO 3D can keep track your device’s movements and captured visual details to match relevant points after scanning. “Loop Closure” technology.

For best performance, combine it with a low scan resolution, check out our 3D scanning recommendations “3D scanning recommendations.

Choosing suitable reference objects

Pick something with distinctive features and colors. For example: a blue couch works well; a plain white wall doesn’t. In construction sites or empty rooms corners work well too.

Let’s do some scanning:

1. Enable RAW capturing at start of scan
2. Snap a photo of your first reference object
3. Continue scanning (check out 3D scanning best practices)
4. Whenever you pass a reference object, capture it again from the same position
5. Complete your scanning route and return to your starting reference object
6. Take a final photo of it (tip: position your iPhone Pro or iPad Pro as close to the floating image as possible)

This creates a closed loop that helps the app correct small errors that accumulate during scanning.

Perform a post scanning optimization

After saving your scan, let MAVO 3D perform an optimization process to improve point cloud quality and remove noise.

Choose between various methods, depending on your available assets (images, RAW data). At the moment we recommend to start with method “Manual Images Only”. It’s fastest and works for most scans, including repetitive environments. This is where your photo checkpoints come in handy ;).

Other methods may achieve higher quality in some cases, but can struggle with repetitive features.

You can always re-optimize later. Your original scan data stays safe.

More optimization methods will follow in the future, as we continue to improve MAVO 3D and its point cloud cleaning and aligning.

What are repetitive patterns?

Structural

Identical structural elements repeated throughout a space, like matching pillars, windows, or similar rooms often found in offices and churches.

Decor

Identical decorative elements, like the same poster appearing on multiple walls in a building.

Best practice: capture manual images strategically. Step back to include surrounding elements in your shots. More context helps alignment and improves scan quality.
