How Can We Help?

Quick Start

You are here:

This section summarises the essential steps for optimal operation of Arago for automated photogrammetric data capture.
Following steps require a certified operator and a fully assembled Arago photogrammetry setup including external devices such as lighting and camera equipment.
Prior to moving on, please make sure that the Hardware and Software installation has been successfully completed.


1. Object placement

First of all, we need to make sure the object fits in the scan space covered by Arago. Generally, any object within 1.5m3 can be scanned by Arago if the geometrical center of the object is on top of the turntable center.

If the XYT component is obstructing the scan space, the user may use the software manual controls to move it backwards for convenience.

The Arago turntable can support objects up to 90kg (±220lbs). Heavy objects must be placed carefully on the turntable to avoid damaging Arago.
Note: objects with larger mass may be supported by other versions of Arago turntables. Contact Rigsters if you need more muscle.


2. Software configuration

Please make sure that Arago Motion Control software has been successfully connected to Arago and the unit initialised.


1. Connect to Camera

Arago motion control software has two options for working with cameras:

  1. Tethering mode – for having a full tethered connection to Nikon or Canon cameras. You can control camera settings, have a camera live view, etc. directly within AMC.
  2. Agnostic mode – in case you are using a camera which is not supported by our tethering, most of the functionality can be accomplished by loading or filling-out the camera settings manually.

For optimal operation of the software, it is essential to define camera settings corresponding exactly to the settings of the camera used.


2. Position 3D model

Under the ‘Object’ panel you can find a list of standard primitives that can be used as a scan target mimicking the real scan object. Position the 3D model on the turntable in the same position as the subject for scanning and scale it to match the subject by using gizmo tools or inputting numerical values in the inspector panel.

A 3D model can be imported from your own library. Note that importing a heavy 3D model may take some computation time as the AMC will perform several optimizations before including it in the scene. Decimating heavy models beforehand is highly recommended.

3. Create scan points

Create scan points. The user has full control for creating scan positions and is aided by several functions. Positions panel offers the following set of generation methods:

  1. Single loop generation
  2. Multiple loop generation
  3. Gradual top loop generation
  4. Imported model mesh analysis and point generation (N/A – in the works)

When generating positions you are able to specify the density of loops, distance to the surface of the scan volumes in their sight, and whether or not they are target or distance locked.

Some positions may not have a direct visual to a point on the surface of the mesh in front of them and the distance to the surface will inexact or unavailable.

All generated loops can be selected and manually adjusted. Individual positions can also be selected and manually adjusted.

Distances from positions to scan volumes are key safety indicators to make sure the locomotion is executed under safe conditions and no accidental collisions with the scan subject occur.
