Terrestrial photogrammetric stem mensuration for street trees

(A) A general representation of the camera positioning – showing image overlap in red; (B) photos were captured in a parallel-manner to the measured trees within the sampled windbreak and right-of-ways – note the control point target within multiple images; (C) processing the photos created a 3D model of each study site; (D) stem diameter was measured from ‘sliced’ point cloud data by selecting two points from opposite sides of each stem.
