World first: Smart Precision Forestry System using Drone Laser Scanning
Subjects of the meeting included "The world's first detection of harvested trees using drone laser scanning and widely used DJI Phantom 4 pro" and "Development, practice, and on-site operation of tree harvest and logging production system using IoT (Internet of Things) harvester".
Prefectural governments, municipalities, forestry associations and timber producers always expend so much energy on forest resource survey before logging practices and logging inspections of cut-down trees. In particular, logging inspection is a big issue to be solved for work-saving of timber production. Professor Katoh's laboratory visualized the cut-down trees by superimposing and subtracting the airborne images taken by drone laser before and after harvest, and successfully developed a calculation method of the amount of logging. It is an innovative work-saving technology that requires only about 10 minutes for measurement, which usually takes a week by labor effort using the field survey method.
This technology is not only an extremely effective practical technology for contributing to forest management and forestry growth industrialization demanded by forest managers and forestry enterprises, but also internationally original research and development.
