About a year ago, I started using computer vision applications to generate three-dimensional models of forests. It all began with a single very red alder (Alnus rubra) tree that was pointed out while giving a tour of a forest stand in Pacific Spirit Regional Park. Below are some images of my initial tests. I have continued to improve my methods by working with leading researchers in the field of computer vision. I also rely on similar tools for my role as the photogrammetry person on the UBC AeroDesign UAV Team, though using custom aerial platforms at a much greater distance to target.
Sunday morning is a lovely time of the week, typically filled with a healthy serving of brunch. Recently, I instead took to the air in the name of science. Join me as I descend a lovely western red-cedar tree while collecting data with one of my purpose-built small aerial sensing platforms:
