A Wytham Tree

A first result from the Wytham scans - a single relatively small sycamore tree, around 20 m high with a dbh of 32 cm. 

The lefthand image shows the point cloud recorded by the TLS, coloured by height (blue to red). The righthand image shows the reconstructed cylinder model, same colour scheme. The reconstruction does a very good job of picking out the main trunk and 1st and 2nd order branching. Less well on the upper parts as usual. This is exacerbated by being only scanned from 5 locations here. As we expand through the plot we will collect more information at the upper part of the trees, and then redo the reconstruction to compare with these results.
May the sun always shine.
