Abstract

This paper concerns the problem of tree height measurement based on image processing embedded in smart mobile phone. A smart phone with camera and a benching marking were used to in our method. Before the tree photo was taken, a benching marking with red colored ends was leaned on the tree closely and parallel to tree trunk. Then the top point of the tree image was extracted according to their color features. And the coordinates of the two marker points on the end of the benching marking were got too. Lastly, the tree height can be worked out using triangle similarity theory. The experimental results show that the relative measurement error of tree height is about 5%. So it is a viable method.
