Xgrids Scans

This document provides developers with instructions on how to process scan data from Xgrids SLAM-based scanners for use with the Multiset developer portal.

You will need Xgrids Lixel Studio and its supporting documentation, which can be found here: https://xgrids.com/support/download?page=LixelStudio

Supported Devices

The following Xgrids scanners are supported:

• L2 Pro: Ideal for large-scale environments.

• K1: Recommended for medium to small-scale environments.

Data Processing Workflow

After completing a scan, the raw data needs to be processed into a specific format before it can be uploaded to the Multiset developer portal. The following steps outline the process of converting the initial LAS file to a zipped e57 file, including the necessary settings for panoramic images.

Please clean up your point cloud to remove all the noise and outliers to get an accurate mesh output, or you can directly use the mesh generated from Lixel Studio.

Step 1: Project Processing

1. Launch the LixelStudio software and create a new project.

2. Navigate to the Processing tab and select Project Processing.

3. In the "Project Processing" window, select your project file.

4. Under the "Coloring" section, ensure that the Output panoramic image checkbox is selected. This will generate the necessary panoramic images to be included in the final e57 file.

Step 2: Data Format Conversion

1. Once the initial project processing is complete, a posescsv file will be generated.

2. In the main LixelStudio interface, go to the Tool menu.

3. Under "Data Management", select the las to e57 tool. This will open the "Data format conversion" window.

4. In the "Data format conversion" window, select the poses.csv file as the "Select Pose File".

5. Set the Panorama interval (m). For large outdoor scans, a setting of 1 or 2 meters is recommended (2 meters for outdoors and 1 meter for indoors)

6. Specify the "Output path" where the converted e57 file will be saved.

7. Click OK to begin the conversion process.

Step 3: File Compression

After the e57 file has been successfully exported, it must be compressed into a ZIP file before being uploaded to the Multiset developer portal.

1. Locate the exported e57 file in the output path you specified.

2. Right-click on the e57 file and select the "Compress" or "Send to > Compressed (zipped) folder" option, depending on your operating system.

3. The resulting ZIP file is now ready to be uploaded to the Multiset developer portal.
