Menu: Settings

The Settings menu in VisionLidar allows users to personalize various aspects of the software, including display preferences, point cloud visualization, classification parameters, object detection, and import/export configurations. The settings are divided into multiple sections:

Settings / Global Settings

  • Language: Select English, French, or Spanish. Project-related names, such as classes and objects, remain unchanged.

  • Vision Database Model: The database model used for virtual surveying and project creation (default: CivilCogo.mdb).

  • Draw in CAD: When enabled, points and chains will automatically be drawn in VisionCivil if it is open.

  • Background Color: Allows selecting the background color of point cloud visualization windows.

  • Vertical Axis: Keeps the vertical axis fixed while rotating the 3D view.

  • Invert Mouse Scroll: Reverses the zoom function when using the mouse wheel.

  • Potree Export Version: Choose the Potree version for web-based visualization (1.4RC or 1.5RC).

  • Source Projection: Defines the coordinate system of the point cloud.

  • Source Unit of Measure: Specifies the unit of measurement for the project.

  • Export to a Single File: Allows exporting multiple scans as a single file.

 

Settings / View

General Visualization Options

  • Point Size: Adjusts the size of displayed points.

  • Point Cloud Transparency: Controls transparency for better visibility of overlapping points.

  • LOD Factor: Determines the level of detail (LOD) based on zoom distance.

  • Field of View (°): Changes the perspective angle for visualization.

  • Drag Speed: Adjusts the speed of dragging the point cloud view.

Picking and Interaction

  • Picking Sensitivity: Controls how accurately points are selected.

  • Use Tentative Point: Enables previewing point selection before confirming.

  • Use Surface Disk: Displays a selection disk when picking points.

Point Cloud Intensity Scaling

  • Min. Intensity / Max. Intensity: Adjusts the intensity range displayed in the point cloud.

Point Labels

  • Main Screen Text Size: Adjusts label size for points in the main window.

  • Road by Sections Text Size: Controls text size in the Road by Sections module.

  • Text Rotation: Defines rotation for text labels.

  • Spaces Before Point Label: Adds spacing between labels and points.

Measurements

  • Measurement Text Size: Adjusts text size for distance and angle measurements.

  • Precision for Angles / Distances: Sets the number of decimal places.

  • Angle Units: Changes the angle unit to degrees, radians, or degrees/minutes/seconds.

  • Areas Shading: Defines shading options (transparent, opaque, or no shading).

Color by Distance to Plane

  • Min. / Max. Distance: Sets limits for the "Color by Distance to Plane" function.

  • Pick Plane Radius / Tolerance: Adjusts plane detection sensitivity.

 

Settings / Import

  • Max. Cell Size: Defines the maximum grid size for imported point clouds.

  • Max. Points in Tile: Sets the limit for points processed per tile.

  • 3D File: Enables 3D file import.

  • Merge Scans: Merges multiple scan files upon import.

  • Compute Normals: Calculates surface normals for imported point clouds.

 

Settings / Classification

General Classification Settings

  • Slope Tolerance: Defines the maximum slope variation for classification.

  • Distance Tolerance: Determines the allowable gap between classified elements.

  • Elevation Tolerance: Limits elevation differences in classification.

  • Limit by Radius: Restricts classification within a set radius.

Sidewalk Detection

  • Min. Segment Length: Minimum detected sidewalk segment length.

  • Direction Tolerance: Maximum angle variation allowed for detected sidewalks.

  • Min. Intensity: Defines the minimum intensity value for sidewalk detection.

 

Settings / Profile & Sections

  • Height / Width: Defines section dimensions.

  • Offset Left / Offset Right: Determines the offset for section views.

  • Height Down: Defines the minimum depth of sections.

  • Interval: Controls spacing between section profiles.

  • Thickness: Adjusts the thickness of section visualization.

 

Settings / Objects

General Object Detection Settings

  • Keep First Outline Only: Enables/disables keeping only the first detected outline.

  • Min. / Max. Points for Detection: Sets the minimum and maximum number of points used for detecting objects.

  • Limit by Radius: Restricts object detection to a specific radius.

  • Maximum Height / Minimal Area: Defines size constraints for detected objects.

Cylinders

  • Min. / Max. Cylinder Radius: Sets detection range for cylindrical objects.

Trees

  • Classify Tree Points: Enables automatic tree classification.

  • Max. Crown Diameter: Sets the maximum detected tree crown width.

  • Crown / Trunk Section Thickness: Determines the thickness of crown and trunk segmentation.

  • Min. / Max. Trunk Radius: Defines acceptable trunk radius ranges.

  • Max. Trunk Height: Sets the maximum height of a detected tree trunk.

  • Max. Crown Radius: Specifies the maximum detected crown radius.

  • Diameter at Breast Height: Adjusts DBH measurement height.

Clusters

  • Cluster Library Folder: Sets the storage location for detected clusters.

  • Separation Distance: Defines the spacing for distinguishing between clusters.

  • Downsample Size: Controls the reduction of point cloud density.

  • Minimum Points: Sets the threshold for cluster detection.

  • Show All Clusters: Enables viewing all detected clusters.

  • Max. Length / Width / Height: Defines maximum cluster bounding box dimensions.
