Trees are one of the more complex objects in VisionLidar, as they consist of two distinct parts:

  1. The Trunk – The base and main support of the tree.

  2. The Crown – The upper branching structure, which can have different shapes.

Each tree includes six key measurements:

  • Trunk Base Center – The precise location of the tree trunk's base.

  • Tree Height – The total height of the tree, measured at the top of the crown.

  • Trunk Height – The height where the first large branch appears.

  • DBH (Diameter at Breast Height) – The trunk’s diameter at 1.3 meters (4.5 feet) above the ground.

  • Crown Diameter – The widest spread of the tree’s crown.

  • Crown Shape – The geometric representation of the crown (spherical or conical).

Creating Trees

Trees can be generated using two methods:

  1. Manual Tree Creation – Click the button, then pick a tree trunk in the point cloud. This method adds trees one at a time to the object list.

  2. Batch Tree Detection – Found under Menu: Analyze / Trees, this tool detects multiple trees automatically and estimates their measurements.

Additionally, manual tree creation requires clicking three points on the trunk plus a fourth point for the Z value to set the trunk’s base (ground level).

 

Modifying Tree Measurements

Once a tree is detected, its measurements can be modified:

  • Redetect Tree – Click the button and select a tree trunk in the point cloud to restart the detection for a specific tree.

  • Manual Adjustments – Modify any tree measurement by picking new points in the point cloud with the  button.

    • DBH & Crown Diameter require selecting two points.

  • Crown Shape – Can be set to spherical or conical. This affects both the display in the point cloud and the exported .DXF file.

 

Trees Toolbar Options

A few additional options are available in the Trees Toolbar:

Description

Deletes all selected trees

Adds a tree to the list; Click on a tree trunk to detect and add a tree.
Alternatively, manually add a tree by selecting three trunk points and one ground point.

Click on a tree in the point cloud to locate and highlight it in the list.

Exports selected trees in DXF, Shapefile, TXT, or HTML formats. TXT and HTML exports are used for reporting purposes.

Creates a COGO point for each selected tree in the list. A Vision database must be attached.
The added points correspond to the center coordinates of each tree trunk base.

Restarts tree detection. The user must pick a tree trunk in the point cloud to regenerate the measurements.

A contextual menu also shows several other features. This is available by right-clicking on a specific tree. The contextual menu allows the user to:

  • Check all/uncheck all to select/deselect all trees

  • Remove current to delete the currently selected tree
