is a system for the non-destructive testing of standing trees for internal defects. It allows for the quick and easy diagnostic of trees by obtaining the speed in which vibrations travel across the diameter of the tree. The system is optimised for its portability and low set-up time to ensure easy and quick diagnostic testing.

 

Functionalities

1. Measure the diameter of a tree using Apple ARKit

2. Provide consistent striking force using trigger

3. Measure the speed of stress wave across the tree

4. iOS app for all-in-one data storage and view

Measurement Subsystem

Measurement creates a 3D model of the tree using Apple’s ARKit and LiDAR technology, allowing for quick and precise mapping of the shape of the tree and therefore the distance between any two points on its diameter
