Using Phyllotaxis for Date Palm Tree
3D Reconstruction from a Single Image

Ran Dror and Ilan Shimshoni

Abstract. Phyllotaxis is the study of the morphological order of plants. Remarkably, in spite of the overwhelming diversity of plant morphology, there are common patterns that link a wide variety of species. The Date Palm, having a phyllotactic order, possesses a simple, repetitive model. Only a small number of parameters are needed to represent the phyllotactic order of the Date Palm. This a priori knowledge we have on the date palm can help in the 3D reconstruction of the tree and can even make it possible to reconstruct a 3D model from only one image. The proposed algorithm receives as input a single image of the date palm. Upon image acquisition, the algorithm proceeds to search for, and locate, the trunk followed by a few prominent leaves. From the location of the prominent leaves the algorithm proceeds to calculate tree model parameters, which can then be used to search for additional, neighboring, leaves. Complete 3D reconstruction is achieved by utilizing the calculated tree model parameters and by the known location of the leaves on the 2D image.

Examples. Several results of the execution of the algorithm, including the VRML models, are presented below. Click on the images for an enlarged version, or for the VRML model. For a complete sequence illustrating the different stages of the algorithm (similar to Figure 4 on the paper), click here.
