Rape plant NDVI 3D distribution based on structure from motion

Plants' morphology changes in their growing process. There is a great need of plant's morphology study for future use like biomass estimation, illness and insect infestation, genotype and other agricultural applications. For now, 3D reconstruction methods can get plants' morphology information. It is meaningful to integrate organic matte distribution information in 3D model. NDVI has been proved to an important index in remote sensing and has a close relationship with chlorophyll density. In this work, Tetracam ADC multi-spectral camera was used. Thirty one multi-spectral images of a rapeseed plant were collected at three different angles under indoor conditions for 3D reconstruction. Computer vision method, i.e. Structure from motion (SFM) was used to process plant's 3D model. The results showed that the attempts to integrate multi-spectral image information into plant 3D reconstruction worked out well and had a potential for plants' organic matters spatial distribution research.
