How to Process Raw Data Directly From the DJI Zenmuse L1 & L2 with LP360

Introduction

This tutorial guides you through processing raw data from the DJI Zenmuse L1 or L2 using LP360. With the new integration with DJI Terra Cloud, you can streamline your workflow without needing DJI Terra Desktop. This step-by-step guide will equip you with the knowledge to import raw flight data, perform RTK processing, set up coordinate systems, create flight lines, and post-process colorized LAS point clouds for further analysis.

Step 1: Import Raw Flight Data

To start processing your raw data, follow these steps:

1. Open LP360.
2. Navigate to the Import section.
3. Select the option for importing raw flights from the DJI Zenmuse L1 or L2.
4. Browse your files and select the raw flight data to import.
5. Confirm the import and wait for the process to complete, ensuring all data is loaded correctly.

Practical Tip: Always check the integrity of the imported files by reviewing the log reports generated during the import.

Step 2: Perform RTK Processing

Once your data is imported, you need to perform Real-Time Kinematic (RTK) processing to enhance accuracy.

1. Go to the Processing menu in LP360.
2. Select RTK Processing.
3. Choose the appropriate settings based on your project requirements.
4. Start the processing. Wait for the software to complete the RTK adjustments.
5. Review the results for any discrepancies and make necessary adjustments.

Common Pitfall: Ensure that you have the correct base station data to avoid inaccuracies in the RTK processing.

Step 3: Set Up Coordinate Systems

Setting up the correct coordinate system is crucial for accurate data analysis.

1. Access the Coordinate Systems settings in LP360.
2. Select the desired coordinate system based on your project needs (e.g., UTM, State Plane).
3. Apply the coordinate system to your imported flight data.
4. Check the alignment of your data points with the selected coordinate system.

Practical Tip: Familiarize yourself with different coordinate systems to choose the most appropriate one for your project.

Step 4: Create Flight Lines

Creating flight lines helps in organizing your data for analysis.

1. Navigate to the Flight Lines section in LP360.
2. Select the imported data and choose the option to create flight lines.
3. Adjust the settings for line spacing and overlap as per your survey requirements.
4. Generate the flight lines and review them for accuracy.

Real-World Application: Well-defined flight lines can improve the efficiency of data collection and analysis, especially in larger survey areas.

Step 5: Post-Process Colorized LAS Point Clouds

To prepare your data for analysis, you’ll need to post-process the colorized LAS point clouds.

1. Go to the Point Cloud processing section.
2. Select your LAS files for colorization.
3. Apply any necessary filters or settings to enhance the point cloud visualization.
4. Execute the colorization process and review the output.

Practical Tip: Utilize colorization to differentiate features in your point cloud, aiding in further analysis like generating contours and DEMs.

Conclusion

In this tutorial, you learned how to efficiently process raw data from the DJI Zenmuse L1 or L2 using LP360. Key steps included importing raw flight data, performing RTK processing, setting up coordinate systems, creating flight lines, and post-processing colorized LAS point clouds. With these techniques, you can optimize your workflow and enhance your data analysis capabilities. Next, consider exploring advanced analysis features in LP360 to further refine your results.
