Estimation of Leaf Area Index Based on Hemispherical Canopy Photography

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
Leaf area index (LAI) is very important for crop growth monitoring, biomass estimation, and many plant growth simulation models. Direct methods are the most accurate, but they have the disadvantage of being extremely time-consuming and labor-intensive as a consequence making them not be the preferred solutions.

Smartphone based hemispherical photography for canopy structure measurement

2017 International Conference on Optical Instruments and Technology: Optoelectronic Measurement Technology and Systems, 2018
The canopy is the most direct and active interface layer of the interaction between plant and environment, and has important influence on energy exchange, biodiversity, ecosystem matter and climate change. The measurement about canopy structure of plant is an important foundation to analyze the pattern, process and operation mechanism of forest ...
