TrueView Multi-Cycle Processing

Introduction

In this article we will explain step by step how to use batch processing for the TrueView sensors, including the current TrueView1 Lite, TrueView1, TrueView515, TrueView535, TrueView545, TrueView655, TrueView660, TrueView680, TrueView720 and Microdrones EasyOneLiDARUHR, as well as legacy TrueView payloads, in LP360 Drone. The article will serve as a quick guide on the processing steps. This article will not explain in detail each of the settings available at each step as those can be found in the linked help articles for each tool as found in the Tools & Feature section of this searchable support knowledge base.

*This article does not apply to processing the TrueView540.

Pre-Requisites

Before starting with the workflow, the user will need to have:

• LP360 v2025.1 or newer
• An LP360 Drone license
• One or more Cycles from a TrueView sensor either on the USB used in the payload or robustly copied to the user's computer using a tool such as Robocopy or TeraCopy. 

1. Import

1. Open LP360 v2025.1 or newer.
2. Select "Import Raw Missions into New Project..." from the Startup dialog or start the Raw Mission Import Wizard using the Cycle Import tool on the Sensor tab.
3. Select "TrueView / Microdrones".
4. Select "Folder" to import the raw data from the sensor. You can select one or more Cycles (flights) to be process in the same project.

5. Select Next.
6. Select the base station file in Trimble T02 or RINEX format --> Next.
7. Select the Project Root Folder and the Project Name.
8. Select the desired CRS.
   
   Tip: If you do not know the CRS, use the suggested WGS84 UTM zone with Ellipsoidal heights. LP360 displays the suggested UTM zone at the top of the Project Coordinate Reference System section.
9. Press Next to see the summary and Finish to begin the import process for the queue of Cycles/Flights.
10. The first column and the message column will indicate the import status with an icon for Queued, Processing, Complete or Error, once the import processing has begun. Upon successful completion of the import queue, proceed with examining the imported files.
    

2. Flight Line Generation

Flight line generation is optional and can be performed later but is recommended to be done prior to sensor processing.

Once the data is imported, you may create flight lines. This step involves selecting the portions of the data you need, excluding unnecessary and lower quality segments like takeoffs and turns, and ensuring that you only work with the most relevant data.

1. Select the Auto-Create Flight Lines tool on the Sensor tab to open the Auto-Create Flight Lines dialog in the Compute Mode.
   
   
   • Flight Line Layer - The name of the layer that will be created and requires no input from the user.
   • Min. Length – No linear set of points shorter than this value will be considered for the calculation of a flight line. This number should usually be set to the shortest flight line length. Use the Measure tool on the main LP360 toolbar to measure the shortest desired flight line.
   • Turn Radius – The radius, in map units, to allow at turns. The smaller the number, the closer the flight lines will be cut to the turns. The greater the radius, the larger the gap.
   • Max Deviation – The deviation parameter that tells the software when to break a line segment into two. The smaller this number, the more linear the flight lines but the more flight lines that will be created. The larger this value, the more “bend” will be allowed in a relatively straight segment without splitting. Hence, increase this value significantly if you have curved flight lines.
2. Once you have entered the desired parameters, select Compute Flight Lines. The number of flight lines created will then populate in the Flight Lines column and the Status will change to Computed. Once satisfied, select Next to enter Edit Mode.

3. On the Edit Mode page of the Auto-Create Flight Lines dialog, the Select/Edit Features tool will automatically be enabled.
   1. Select flight lines you wish to delete, then click the Delete key then the Enter key on your keyboard.
   2. Hold control while selecting to select multiple flight lines. Or drag to select multiple flight lines from the same Cycle.
   3. Repeat for each Cycle, as desired.
4. After editing the flight lines, the Status will change to Edited to indicate a change has been made. Any edits made within Edit Mode will automatically be saved.
5. The flight line layer should be created, and the flight lines displayed in blue in the map view.
   • Results can be changed by changing the parameters and selecting Compute Flight Lines again. The existing lines will be replaced with the results from the new settings.

3. Sensor Processing

1. On the Sensor tab of the ribbon, select Sensor Processing Launcher to open the Sensor Processing dialog.
2. Select the desired tasks to be performed, typically Trajectory Processing and Geocoding. Note you may also run those two tools separately instead of using the Sensor Processing Launcher.
3. Select Next.

4. On the Trajectory Processing page, select the flights to be process --> Press "Trajectory Processing Settings" -->Set up the desired settings --> Close the Trajectory Processing window --> Press Next

Tip: TV1 and TV1 Lite Settings

5. On the Geocoding page, select the flights to be process --> Press "Geocoding Settings" --> Set up the desired settings --> Close Geocoding windows --> Press Finish

Tip: TV1 and TV1 Lite Settings

6. Go to Job Manager to monitor the processing status.
   
7. Once the jobs are completed, it will appear as "Ready" in the Job Manager --> Select the job, then "Complete Job".
   Note: Run "Complete Job" for all jobs, not just one.

8. Once the Sensor Processing has completed, then the point cloud has been generated, and it is recommended to review the trajectory processing reports.

4. Next Steps

We then recommend continuing with the recommended workflow.

1. If flight lines were not generated prior to running the Sensor Processing, then create flight lines now using Auto-Create Flight Lines .
2. Optionally, run Post Processing if you created flight lines after Sensor Processingor wish to otherwise filter the point cloud.
3. Optionally, run Strip Adjustment to improve the flight line to flight line matching by minimizing the dynamic sensor trajectory errors.
4. Run QA/QC analysis on your data set, such as Creating a Control Point Report , etc.
5. Optionally, debias the point cloud. 
6. Optionally, run Smoothing on your point cloud.
7. Optionally, remove noise using the Outliers Removal and run the Ground Classification workflow or use the new Auto AI Ground Classification .
8. Optionally, create a quick orthophoto using Ortho Mapping , or generate a DEM and create a high quality orthophoto using Agisoft Ortho Mapping .
9. Utilize the extensive capabilities of LP360 for additional classification, vectorization, and derivative product generation.
