Abstract :
It has been possible to acquire precise point clouds of surface features from terrestrial laser scanner data. And it is a research hot spot to figure up the LAI of a single tree or wood combined data clouds model of single tree with gap fraction model. We used the point clouds of a single tree from field measurements combined with gap fraction model to estimate the LAI. And we found that a reasonable result could be computed in this way.
