Requires an LP360 Land Basic or higher license.

Introduction

In this article we will explain step by step how to process a TrueView GO (TVGO) handheld mapping dataset in LP360. This article is divided in 2 sections, steps to process TVGO and example on how to process a TVGO step by step. This article will not explain in detail each of the settings available in each step, but it will point user where to find more information. It is also useful to complement this article the LP360 Land User guide.

TrueView GO Processing Workflow

This section is an example of how to process a TVGO step by step. The settings selected in this example should work for any typical dataset captured outdoors.

Import

  1. Select “Import Raw Missions into New Project…” in the Startup Dialog TrueViewIcon_Start up dialog.png or select Import Cycle TrueViewIcon_Import Wizard.png on the Sensor tab of the ribbon.
  2. Select “TrueView GO”.
  3. Press “FolderAdd16.png Add Cycle” to import the raw data from the sensor. You can select one or more Cycles (datasets) to be processed in the same project.

Note: The very first time you select TVGO data or when an update is available, you will be prompted to install the LP360 Sensor Extension.

  1. Press Next.
  2. Configure the Project Settings:
    • Select the Project Root Folder and the Project Name.
    • Select the desired CRS.
      • Tip: Select "Local Coordinate system" for SLAM datasets

  1. Press Next –> The summary will be display –> Press Finish.
  2. Data imported.

Point Cloud Generation

Once the cycles are imported into LP360, there will not be much data to review yet, and you will be prompted to setup the SLAM Processing TrueViewIcon_SLAM.png for computing the trajectory solution and generating the point cloud.

  1. Open the or SLAM Processing TrueViewIcon_SLAM.png dialog for single Cycle job queueing or use the Sensor Processing Launcher SensorProcessing.png for simultaneous configuration for multi‑Cycle processing with an Unlimited add-on license.
  2. Specify the Processing Mode: 
    • PPK - Requires Base Station Observation and Survey Nail/Reference Mark.
    • RTK - Requires RTK corrections recorded during the data acquisition. RTK Geographic CRS must be specified.
    • GNSS - available when GNSS but no RTK corrections were acquired during the Cycle.
    • SLAM
    • Realtime - Good for quality control or helping to figure out the location of TGCP (TVGO Control Points).
  3. Optional: If TGCP (TVGO Control Points) were collected during data acquisition, press the TGCP: Unassigned button under Trajectory GCPs select to open the TrueView GO Ground Control Point Measurements dialog to configure the points for use.
  4. Press Next.
  5. Configure the SLAM - Geocoding Settings: 
    • Lidar Processing
      • Scene Type: Modify based on Processing Mode (Indoor, Outdoor, Mixed, etc.)
        • Point Cloud Optimization - recommended
        • Moving Objects Filter - recommended
        • Point Cloud Denoising - Optional - disabled by default
      • Laser Filter Settings - Optional - disabled by default
    • Photo Processing
      • Settings 
        • Remove Uncolored Points - Optional - disabled by default
        • Update Photo EXIF Tags - recommended
        • Use Street View Photos - For Insta360 photos processing
      • Colorization Method - Fast option recommended
  6. Press Submit.
  7. Open the Job Manager TrueViewIcon_Job Manager.png located on the Sensor Tab to monitor the status of your submitted TGO jobs.

Selecting Job Manager and viewing State of Jobs (outlined in red)

  1. Once processing is complete, the State will be listed as PostProcess16.png Ready. Select the job and press the PostProcess16.png Complete Job button.
    • The point cloud is generated and added to the Table of Contents. 
    • Note: no filters are applied.
  2. Review the Trajectory Plot TrueViewIcon_View Post Process Trajectory Plot.png to check the quality of the data collection.
  3. Optional Create flight lines, i.e. walking paths using the Time-based method in Auto Create Flight Lines TrueViewIcon_Auto Create Flight Lines.png, or by using the Manual Flight LinesTrueViewIcon_Create Flight Lines from Selected Trajectory Point.png tool before using the Post Processing TrueViewIcon_PostProcessing.png tool for additional filtering or for better insight into alignment between different times of the data collection.
  4. Optional To filter the data or assign point source IDs, and generate a new point cloud, open the Post Processing tool TrueViewIcon_PostProcessing.png found on the Sensor Tab of the ribbon.
    • Disable Clip Angle for TVGO datasets as 360° of the scans is typically desired.  
    • Select the Clip Range. This will remove points that are outside the minimum and maximum distance from the sensor.
      • Tip: Optional. If desired, use 0 to 20 to filter any point further than 20 meters from the scanner. Adjust as needed.
    • Enable Update Photo EXIF Tags with True Pose® Information.

Next Steps

Modeling

Create 3D models using Modeling TrueViewIcon_mesh_modeling.png

Control Points

Learn more about TGCPs processing with the TrueView GO

The user will need to measure multiple targets during the data collection with the TVGO and later have the targets coordinates (measured by a different sensor, for example an RTK rover).

The TGCPs workflow requires at least four GCPs are measured and is strongly recommended to georeferenced SLAM datasets or outdoor datasets with poor GNSS coverage.

Point Cloud Registration

If you have multiple TVGO datasets, it is highly recommended to perform "Registration" before doing any additional processing.

There are three options for point cloud registration available:

LAS to LAS Manual Registration
LAS to Control Manual Registration
LAS to LAS Auto Registration

Noise Removal

Point cloud datasets will at times have noisier than usual low/high point noise that will need to be classified/removed from the project data. This can be caused by vegetation, site movement (conveyor belts), water presence, etc. LP360 contain multiple methods available for removing this noise.

Learn more about noise removal options

Smoothing

This step is optional. The Smoothing PCT will help reduce the point cloud noise envelope or the thickness of the point cloud. This algorithm works well for manmade structures, flat areas or regular surfaces. 

Learn more about Data Smoothing in LP360

Classification 

LP360 offers a variety of classification options. The most common in LP360 is Ground Classification. 

Learn how to Classify Ground

Point Cloud Tasks (PCTs) can also be used to perform other processes on the data for classification or modification purposes.

Exporting or Extracting Final Products/Deliverables

Use the Export Wizard TrueViewIcon_Export Data.png, Generate Products TrueViewIcon_GenerateProduct.png, or Export TIN LandXML TrueViewIcon_Export LandXML.png, to create a variety of deliverables from your TrueView GO data.
