As digital technologies are advancing quickly allowing autonomous cars and trucks to move on our highways, the dream to use these digital technologies for automated forest inventory is very close to becoming a reality.

Both hardware (e.g., LiDAR and digital cameras) and software (e.g., AI) are advancing quickly and becoming economically affordable. This can allow advanced computing (e.g., AI) and multi-dimensional data from various sources to be used in forest systems to improve information gathering and decision-making.

Improvements in digital technology have helped lay the foundation for their potential application in forest productivity and management. However, the integration of these digital technologies into forest inventory is still lacking, hindering inventory automation and data-driven traits selection for tree improvement and precision management.

The objective of the research is to develop a terrestrial system/platform and biometrics extraction algorithms for fine-detail, automated measurements and trait characterization for forest plantations. The system is based on an integrated RGB camera, LiDAR, and Global Positioning System/Inertial Navigation Systems (GPS/INS) units. The integrated sensors can be mounted onboard a backpack or an all-terrain vehicle.

  1. Optimize system integration, data logging, and deployment.
  2. Develop data processing and biometrics extraction algorithms.
  3. Share tools and methods with HTIRC researchers and stakeholders in trainings and workshops.
