Requires an LP360 Land Basic or LP360 Land Standard license.
While importing a new TVGO Cycle for processing, processing modes and extra advanced settings are available in the "Raw Mission Import Wizard - Input Settings".
Mode
The mode or processing mode, allows the user to select the type of reconstruction:
- SLAM: It will use only SLAM algorithms during the reconstruction. Recommended for Indoor datasets. It can use a local or a global coordinate system.
- RTK: It will mostly use GNSS + IMU georeferencing information for the reconstruction, however, It may use SLAM algorithm to enhance areas with poor GNSS solutions. Recommended for outdoor datasets. It requires RTK corrections during the data acquisition.
RTK Geographic CRS & Epoch: Coordinate Reference System for the RTK corrections. Usually, the RTK corrections are in a Global CRS in LLH in meters with the associated CRS Epoch. The most common RTK CRS used are:
- World: WGS84 + Ellipsoidal (Meters), Epoch 2015
- North America: NAD83(2011) + Ellipsoidal, Epoch 2010
- Europe: ETRS89 + Ellipsoidal (Meters), Epoch 1989
- PPK: It will mostly use GNSS + IMU georeferencing information for the reconstruction, however, it may use SLAM algorithm to enhance areas with poor GNSS solutions. Recommended for outdoor datasets. It requires a base station observation file to correct the trajectory.
Reference Mark: Coordinates of the base station. Use the Survey Nail Manager to store and manage your Reference Mark.
Base Observation File: this tool allows the user to import a base station or observation file, in .T04 or Rinex format. It is recommended to use Rinex 3.04 or newer.
Note: All datasets can be processed in SLAM mode, if the dataset contains GNSS information, it will be ignored. A RTK-acquired dataset, can be processed in PPK mode too if the user has an observation file, the RTK information will be ignored.
Advance settings
The TrueView Go Advanced Settings provides extra settings for the TVGO processing.
Colorization Method: This setting controls the colorization type required
- None: generates a non-colorized point cloud
- Fast: Recommended colorization point cloud
- High Precision: Highly intensive colorization that preserves better the real features colours. However, it is time-consuming. Note: This setting requires a NVIDIA graphics card. It is recommended a 3050Ti series and above GPU, Intel Corei7 and above CPU.
Scene Type: This setting helps the algorithm to improve the 3D reconstruction
- Indoor (No GNSS): Recommended for Indoor areas. It will be automatically selected if the user selects “SLAM” mode.
- Outdoor (GNSS): Recommended for Outdoor areas with GNSS reception. It will be automatically selected if the user selects “RTK” or “PPK” mode.
- Mixed Indoor and Outdoor: Recommended for projects with areas both outdoor and indoor, in this type of projects, most of the work is done outside with GNSS reception, however, there will be small areas surveyed indoors without GNSS reception.
- Narrow, Closed Spaces: Recommended for indoor corridors or narrow spaces.
- Sparse in Features: Recommended for datasets with few vertical objects and empty spaces. The algorithm will use the ground heavily as a reference.
Moving Objects Filter: Filter that will try to clean moving objects from the point cloud.
Apply Settings to All Cycles: Select this option to apply the same settings selected to all the cycles.
Use All Satellite Constellations: Allows the user to select what GNSS constellations to use. GPS, Galileo, GLONASS and Beidou are global. QZSS is regional for Asia - Oceania.
