Non-destructive three-dimensional reconstruction is required to precisely determine plant morphology and its changes. We developed a space-efficient and low-cost three-dimensional reconstruction system for plant architecture of Arabidopsis thaliana, which can be easily obtained in laboratories specializing in plant science. In this system, images of a plant rotating at low speed on a rotator are captured by a camera from multiple directions and a three-dimensional image is reconstructed based on the visual volume intersection method. The accuracy of the three-dimensional reconstruction was verified using a three-dimensional model of known size and shape. It was observed that 360 images captured at intervals of approximately 1° were sufficient to obtain accurate three-dimensional images with submillimeter resolution and high shape reproducibility. Our system is expected to contribute to the promotion of multi-dimensional phenotyping of plant architectures.
