Emesent
Prevu3D supports the following scanners from Emesent:
Emesent software for processing:
Data Processing
Section titled “Data Processing”Export Settings
Section titled “Export Settings”In order to process Emesent dataset inside Prevu3D, we require the following files from your Output folder:
-
Pointcloud (either LAS/LAZ or E57)
-
Trajectory file (XYZ)
-
[Optional] Pictures
-
[Optional] Pictures information file (frames_prevu3d.csv)
Step 1: Pointcloud Processing & Trajectory
You will require to launch a Processing job on Aura to prepare your pointcloud. Once the processing is completed you may open the folder containing all the processed files.
You should find the pointcloud & the trajectory file. You can upload those 2 files on Prevu3D.
Step 2: Colorization (Recommended)
Emesent’s colorization feature allows you to augment your point clouds with true color, providing additional context for visualization and analysis. Colorization works by merging the scanner’s LiDAR data with imagery captured during the scan — from a GoPro mounted to Hovermap, or from the GX1’s integrated cameras.
Check that you have everything necessary to create a colorized point cloud:
-
Your scan folder (containing the raw data from your device).
-
The associated imagery (for Hovermap, a GoPro MP4 file within the scan folder; for the GX1, the integrated camera imagery captured during the scan).
You will be able to configure your New Scan Job and select the Colorize workflow.
Once the processing is completed you can open the folder containing your processed files and should find the pointcloud with “_colourised” in its name.
You will be able to upload this colorized version instead of the one from Step 1.
Step 3: Pictures & Pictures Informations (Optional)
The image frames used during colorization can be exported with the colorized point cloud. You can find them in the Intermediate files > frame_extraction > frames folder.
You can upload all the jpg files with the frames_prevu3d.csv
