The research of tree growth based on image vision theory

This article researches the applications of tree growth status tracking based on binocular vision. We conducted experiments using dual-camera of parallel optical axis to capture images, by the way of looking feature points calibrated in the tree´s image to match the two images of trees. We calculated the spatial information change of the trees marked point within a certain time interval changes, and determined the center point of the horizontal, vertical and depth of changes in the three coordinate directions. Aware of changes in tree diameter and height, we determined the status of tree growth.
