Abstract : 3-D measurement of rice canopy is effective for growth analysis, photosynthesis evaluation, and reflectance modeling. But, digital measurement has been hardly carried out because 3-D measurement of plant canopy is difficult.
In this paper, past studies on stereo matching are reviewed and it is shown that not only information of similarity but also that of continuity is necessary in order to match each point of rice vertical images. Therefore, a new matching algorithm for rice plant images is proposed. The algorithm is based on recognition of the top of a leaf and a following outline of the leaf. Rice 3-D shape was measured presicely with this algorithm.
