You are able to upload a tiled model generated with CapturingReality RealityCapture to Trendspek. To do this, follow the below steps.

Add custom camera export for Trendspek

We need to add a custom camera export by editing calibration.xml found within your RealityCapture installation directory, i.e C:\Program Files\Capturing Reality\RealityCapture

Add the following above the last line </Calibration> in calibration.xml

   <format id="{59d6558e-e8e0-4800-bf1a-d5ffdc3b0368}" mask="*.csv" descID="9000" desc="Trendspek Camera Export" writer="cvs" requires="component">
        <body EulerFormat="zyx">#name,width,height,x,y,alt,heading,pitch,roll,f,px,py,k1,k2,k3,k4,t1,t2
$ExportCameras($(imageName)$(imageExt),$(width),$(height),$(x),$(y),$(z),$(yaw),$(pitch),$(roll),$(f*36),$(px),$(py),$(k1),$(k2),$(k3),$(k4),$(t1),$(t2)
)</body>
    </format>

Save calibration.xml and restart RealityCapture

Export LOD mesh and Camera Data

We will assume you have already aligned your imagery, built and textured a mesh. Your view will likely look similar to below.

  1. Begin by navigating to Application Settings > Coordinate systems and change the Output Coordinate system to epsg:4978

  2. Under the Mesh Model tab, click on Levels of Detail under Export.

    1. Create a folder to contain the export called 3d-tiles

    2. File name tileset.json

    3. Save as type: Cesium 3D Tiles (.json)

  3. Under the Alignment tab, click on Registration under Export

    1. Export to the folder made in the previous step 3d-tiles

    2. File name cameras.csv

    3. Save as type: Trendspek Camera Export

    4. Export transformation system > Coordinate system Project output

    5. Altitude: Unmodified

  4. Zip folder 3d-tiles to create 3d-tiles.zip

Upload to Trendspek

Start by navigating to https://trendspek.cloud/d/uploads If you are unable to access this page, you may not have sufficient privileges. Contact Trendspek Support or your account admin to confirm. Create a new upload and ensure you select RealityCapture as the upload type.

Upload the following items in one go:

  • 3d-tiles.zip

  • the original jpg imagery

    • Do not drag a folder of imagery to Trendspek, instead, drag the imagery itself or use the file picker

The Trendspek team will perform a final quality control step before making your dataset available in your account. You will receive an email once it is ready,
