The VLX 3 is a wearable terrestrial scanner - it sits on your body and captures the environment around you. The VLX 3 uses LiDAR-based **SLAM (Simultaneous Localisation and Mapping)** technology. \
\
It is often used in navigation where there is continuous movement; i.e., in cars. SLAM is able to map out the environment and also place the device spatially in that same environment.\
\
In the VLX 3, as you walk around it will automatically build up the dataset, aligning individual scans is not as required in this workflow, making it faster and more accessible.

## The Kit

The VLX 3 kit comes in a hard case containing the following:&#x20;

There will also be some cleaning cloths, replacement parts and other miscellaneous items.

## Workflow

### Evaluate + Plan

For any 3D scanning project, it is best to plan out how you will approach the scanning - where to best take the scans, how many scans as an indicator of time, scan quality, and more. You can start with the BLK360 Benchmarking guide here:

{% content-ref url="leica-blk-360/blk360-benchmark" %}
[blk360-benchmark](https://ms-kb.msd.unimelb.edu.au/next-lab/3d-scanning/guides/leica-blk-360/blk360-benchmark)
{% endcontent-ref %}

The main differences are instead of individual single scans, the VLX 3 will scan continuously as you move; so you will need to consider your route as a continuous walk and ensure you are navigating around occlusions to ensure a complete scan.

Planning out your route means that you prepare exactly how to approach the walk - having a floorplan or visiting the location early can help - you don't want to just start scanning without an idea on how you intend to move. More details are covered in 2.
