Occlusion-aware 3D Reconstruction for Plant Phenotyping (JSPS KAKENHI 2021-2024)
This research aims to construct a technical system for “occlusion-aware 3D reconstruction,” which reconstructs 3D shapes, including occluded (hidden) areas, from images taken from a single or multiple viewpoints. The reconstruction of the occluded area is essentially an unavoidable problem in the recognition and understanding of many scenes in this world. The method we construct in this research will be a new 3D reconstruction framework that estimates the 3D shape in such a way as to complete the occluded area on the image and in space, based on prior knowledge of the structure and similarity of the target object.
