Canopy Reconstruction 

Accurate and useful models of plants in three dimensions, based on multiple colour images using a low-cost camera.

Our reconstruction work aims to produce accurate and useful models of plants in three dimensions, based on multiple colour images using a low-cost camera. Beginning with an initial point cloud, obtained using standard structure from motion tools, the scene is first filtered, and segmented into small patches that represent sections of leaf surface. Each surface is individually represented by a best-fit plane, and the boundary of each surface is adjusted to better fit the image and modelling data. This adjustment is achieved using the level set method, which optimises the smoothness of each surface, while growing or shrinking them in response to image information and neighbouring surfaces.
