Faro SCENE

Export instruction for Faro Scene

Updated over a week ago

The point cloud in E57 format, into subfolder "pointclouds":

In SCENE's Export tab, click the Export Scans button; from the dropdown choose Export Scans - Ordered.

Choose E57 as the format.

Tick the checkbox [✘] Export each scan into a separate file. Tick the checkbox [✘] Full Color Resolution Panorama Image.

  • If this checkbox is missing or if you have some scans that were scanned without colour, go to Exporting full resolution panos from SCENE.

  • If you use the Faro + Ricoh Theta integration instead of the builtin scanner RGB camera, go to Exporting Ricoh panos.

Do not submit "Unordered" point clouds or "Project Point Clouds", as these do not contain the original scanner positions.

Highly recommended:

The Project Point Cloud as E57 into subfolder "coloring-pointclouds". SCENE's Project Point Cloud with Color Correction enabled makes for much better colors. Unfortunately they do not retain scanner positions, which is why they are needed in addition to the "Ordered Scans" export.

  1. Disable all clipping boxes to ensure the project point cloud is not truncated.

  2. In SCENE's Explore tab, click the Project Point Cloud button; from the dropdown choose Create.

    • Tick the checkbox [✘] Apply Color Balancing.

    • (Optional but recommended): Tick Homogenize Point Density. Choose a Cell Size of 2mm.

  3. In SCENE's Export tab, click the Export Project Point Cloud button.

    • Choose E57 as the format.

Double-check that the number of files in the export folder is as expected.

You can find a screenshot of what the final export folder should contain in the section below Reviewing a SCENE export.

Step 1: Exporting ordered Scans via the Export tab:

Step 1 (alternative): Exporting a subset of the project as ordered scans via right-click in the project structure:

Steps 1 (b),(c),(d): Choosing the E57 file format, enabling separate files and pano images:

Step 2: Creating and exporting a color-corrected Project Point Cloud:

Exporting full resolution panos from of SCENE

You should follow the steps in this section if either:

your version of SCENE is too old to have the checkbox [✘] Full Color Resolution

Panorama Image to embed the panos into the E57 files, or you scanned some scans without colour and you want to display them in grayscale in AIM (SCENE cannot currently embed grayscale panos into E57 files); in that case choose option (b) below.

Then you should export the panos as separate files:

Export the RGB image data, into subfolder "panos".

You have two choices:

  1. Full-quality panoramas (recommended):

Right-click on the desired Project or Cluster, and choose Export, Export Panoramic Images, Full Color Resolution.

  1. Downsampled quality panoramas (not recommended, but faster and smaller): Choose Scan Resolution instead of Full Color Resolution.

This will allow you to choose the image file type.

Prefer PNG (a lossless format) over JPEG (a lossy format).

Exporting Ricoh panos from SCENE

Only if you use the Ricoh Theta camera integrated with the Faro scanner as a replacement of the Faro internal RGB camera, you cannot use "Full Color Resolution Panorama Image" because the Ricoh images do not count as "full resolution".

Instead:

In newer versions of SCENE (at least >= 2023.1), ensure each scan has a matching "PanCam Scan" otherwise, only grayscale intensity panos will be exported in the next step.

If they do not exist yet, right-click your project and choose Operations, Create PanoCam Scans.

Into subfolder "panos", export the Ricoh images that SCENE reprojected onto the laser origin (noticeable as it creates white outlines around the edges of objects).

Right-click on the desired Project or Cluster, and choose Export,

Export Panoramic Images, Scan Resolution.

Optional, but very recommended:

Into the subfolder "external-panos", save the original Ricoh RGB photos.

You cannot retrieve them from SCENE, but instead from the scanner's SD card, from the folder of each scan ("fls") in the subfolder "PanoCam".

Note these images need to be in equirectangular, not double-fisheye format. AIM can currently only process equirectangular Ricoh panos in this step.

If your panoramas are double-fisheye, you can skip this entire optional step.

If you provide these images, AIM can register them against the

SCENE-reprojected images above, so that they are shown in the tour as well. Please check that these images are stitched equirectangular photos, not

double-fisheye circles.

Any double-fisheye circle photos need to be stitched into equirectangular first.

Exporting images from a non-Faro camera

SCENE optionally also supports importing photos that are made not by the laser scanner itself, but by a different camera mounted onto the scanner tripod in the same or a close-by position. It can colorize the scans using this external imagery.

You may want to use this external imagery in your AIM tour.

In this case, the export steps remain the same, but you need to additionally provide the external imagery into a folder: external-panos

Be aware that if you have used external imagery for colorization, the Export Panoramic Images functionality in SCENE will not export the external imagery, but re-colorized laser scans. You can recognize this by black or white outlines around objects:

Comparison between original external image vs. exported colorised scan panorama with outline:

It would be desirable to show only the original imagery in the AIM tour, using the image positions that SCENE has already computed ("PictureFit"). However, to our knowledge, SCENE does not provide a way to export the exact pose data of the original images. Their positions can be slightly offset, and the images will usually be placed with an arbitrary rotation around the laser's vertical rotation axis.

In absence of an export method, you can provide AIM with the original images, and we will use photogrammetry to register (place) them automatically against the colorized scans you provided.

If your original panoramic images (must be in equirectangular format) are managed outside of SCENE (preferable), simply copy them into the external-panos folder. If you can access them only through SCENE, re-export them by expanding the Pictures section of each Scan in the Structure view, Right-click on the image file ->

Export, and choose preferably a lossless format (e.g. PNG).

Reviewing a SCENE export

When you are done, the export folder should look as follows:

name-of-your-export-folder

pointclouds

myproject001.e57

myproject002.e57

...

panos (only if your SCENE version cannot embed them into the .e57)

myproject001.png

myproject002.png

Pano_FARO_Scan_000.jpg (if you use the Faro-Ricoh integration the files are named this way instead)

coloring-pointclouds

myproject-project-pointcloud-4mm.e57 external-panos (if you use the Faro-Ricoh integration or make additional panocam shots; must be equirectangular)

R0011533.JPG (named this way if you got the Ricoh equirectangular photo directly from the Faro SD card)
