Menu: Explorer / Objects / Trees
Trees are some of the more complex objects in VisionLidar. Besides having a position, they are made of two distinct parts; the trunk and the crown. Six types of measurements are associated with each tree:
The center of the trunk’s base
Tree height (top of the crown)
Trunk height (where the first large branch appears)
DBH (diameter at breast height)
Crown diameter
Shape (of the crown)
They are created either individually using the 
Clicking on the 
button will restart the detection for a specific object and a tree trunk must be picked in the point cloud. The function will automatically detect measurements for that tree. Each measurement for any given tree may be changed manually by picking points in the point cloud with the "..." button and picking the desired point in the point cloud. (Note: For DBH and crown diameter measurements - 2 points must be picked.) The shape of the tree can either be set as spherical or conical; this is how it will be displayed in the point cloud and in the exported .DXF file.
A few options are available in the trees toolbar - see their description here:
| Icon | Description |
|---|---|
| Deletes all selected trees |
| Adds a tree to the list; expects the user to click on a tree trunk to detect a tree on screen | |
| Invites the user to click on a tree to be identified on screen; the tree in question will be highlighted in the list |
| Exports selected trees to .DXF, shapefile format. Exports to .T XT and .HTML formats for reporting |
| Creates a COGO point for each selected tree in the list. A Vision database must be attached. The points added correspond to the center coordinate for each tree trunk base. | |
| Restarts the tree detection and a tree trunk must be picked in the point cloud |
A contextual menu also presents a few extra 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
