Abstract

This document describes the computer vision method for DBH measurement based on pictures collected in an outdoor environment designed by Brno University of Technology.
The DBH (Diameter at breast height) refers to tree diameter measured at 4.5 feet above the ground. The method is based on detection and localization of the predefined card placed on the tree-trunk. The work includes and the report contains:

  • design of the computer vision methods for card detection and localization, and tree-trunk segmentation,
  • analysis of the methods reflecting the practically maximal achievable accuracy and also the stability of the method (e.g. ROC),
  • monitoring the computational efficiency of designed methods reflecting the requirement of running the solution also on old-type smartphones (like Galaxy J1, but also actual types),
  • documentation of the C++ library implementation with API defined together with FVW team.
