TrueView Multi-Cycle Sensor Processing

1. Introduction

In this article we will explain step by step how to use batch processing for the TrueView sensors, this includes, TV1 Lite, TV1, TV515, TV535, TV545, TV655, TV660, TV680, TV720 and Microdrones EasyOneLiDARUHR in LP360 Drone. The idea of the article is to serve as a quick user guide on processing. This article will not explain in detail each of the settings available in each step, that can be found either in the help section or in the LP360 Drone User guide. This tool is also called, sensor processing.

*This article does not apply if you are processing TV540 sensor.

1.1. Pre-Requisites

Before starting with the workflow, the user will need to have LP360 v2025.1 or newer. It is also required a LP360 Drone license.

2. Import

1- Open LP360 v2025.1 or newer
2- Select "Import Raw Missions into New Project..."
3- Select "TrueView / Microdrones"
4- Press "Folder" to import the raw data from the sensor. You can select 1 or more cycles (flights) to be process in the same project.

5- Press Next
6- Select the base station file in 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, you can always select WGS84 UTM zone XX in Ellipsoidal heigh. LP360 shows the recommended UTM zone.
9- Press Next --> The summary will be display --> Press next
10- Data imported

3. Flight lines generation

Flight line generation is optional and can be done later.

Once the data is imported, LP360 allows you to create flight lines. This step involves selecting the portions of the data you need, excluding unnecessary 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.
   
             
   • 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, click Next.
   
   
   
3. On the Edit Mode page of the Auto Create Flight Lines dialog, the Select/Edit Features tool will automatically be enabled.
   
   • Select flight lines you wish to delete, then click the Delete key then the Enter key on your keyboard.
     • Hold control while selecting to select multiple flight lines. Or drag to select multiple flight lines.
   • 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.
4. 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.

4. Batch processing

1- Go to "Sensor" ribbon --> Sensor Processing
2- Select the tasks to be performed --> Press Next

3- In the trajectory processing window select the flights to be process --> Press "Trajectory Processing Settings" -->Set up the desired settings --> Close the Trajectory processing windows--> Press Next

Tip: TV1 and TV1 Lite settings article
4- In the geocoding window 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 article

5- Go to "Job manager" to monitor the processing status

6- Once the jobs are completed, it will appear as "Ready" in the "Job manager" --> Select it--> Press "Complete Job".
Note: press "Complete Job" on all jobs, not just one.

Point cloud generated, at this point it is recommended to review the trajectory processing reports.

After this step we recommend continuing with the True View recommended workflow. Some of the steps recommended are "Post Process",  "Strip Adjustment", "Smoothing", "Control Points", "Outliers removal" or "Ground Classification".
