Plant Orbiter: 3D Plant Reconstruction and Generation with Video Diffusion Orbit Cameras and 3D Gaussian Splatting

원문 초록

Modern digital phenotyping pipelines require the precise measurement of a range of 3D morphological plant traits. The accurate, high throughput acquisition of these traits helps breeders and researchers accelerate the development of new varieties, techniques and products. Recent advances in 3D technologies have enabled a rapid transition from 2D to 3D pipelines, but high throughput acquisition of digital 3D twins of plants remains a significant challenge due to complex morphology, thin structures and occlusions. In this paper we present Plant Orbiter, a new approach to generating 3D plants that leverages recent advances in video diffusion to produce high quality 3D Gaussian Splats of plants from a single image. We show that our method more accurately recreates plant morphology than other state-of-the-art methods, achieving the highest 3D F-score against all baselines, while being more practical for high throughput pipelines due to easier alignment and reduced cost of camera placement. Combined with a 2D diffusion model, we show that our method also achieves state-of-the-art results in the generation of 3D plant models from a text prompt.
