Extracting Individual Sensor Point Clouds from Gemini Detect PCAP Exports Using Ouster SDK

Overview

When exporting data from Gemini Detect, the PCAP file may contain point cloud data from multiple sensors. This guide explains how to use the Ouster SDK to selectively extract and view point clouds from individual sensors.

Solution Overview

Gemini exports a combined PCAP file.
Each sensor has its own associated metadata JSON file.
Use the Ouster SDK to specify which sensor's data to extract or view.

Step-by-Step Guide

1. Install Ouster SDK

Refer to Ouster SDK Installation Guide

2. Extract Individual Sensor Data

Run the following command:

ouster-cli source -m [your_metadata.json] --soft-id-check [your_pcap.pcap] viz

Replace:

[your_metadata.json] with your specific sensor’s metadata file.
[your_pcap.pcap] with the exported PCAP file.

Example:

ouster-cli source -m 10_12__12_11_21_992209000047.json --soft-id-check 1024_10.pcap viz

Extra Tips

Soft ID Check is needed if your PCAP contains multiple sensors.
You can visualize the points live using the viz option.
You can also convert the PCAP into other formats:

Important Reminders

Always ensure your .json file matches the sensor ID inside the PCAP.
Ouster SDK allows manipulation of point clouds for further external processing (e.g., PCD, CSV export).
