Abstract

The invention discloses a leaf area index measurement system based on a wireless sensor network. Its front-end node is used to take canopy images, and calculates the leaf area index according to the canopy image, and sends it to the collection node. The collection node is used to use the front-end node The sent leaf area index is forwarded to the sink node through the wireless sensor network, and the sink node forwards the received leaf area index to the host computer, and the host computer receives the leaf area index and stores it, and provides a query interface for the staff to query. Based on the wireless sensor network, the invention makes the leaf area index testing system more flexible and efficient.

Description

technical field [0001] The invention belongs to the technical field of leaf area index (LAI for short) measurement, and more specifically relates to a wireless sensor network-based leaf area index measurement system. Background technique [0002] Vegetation is an important component of terrestrial ecosystems, and leaves are an important organ for the interaction between vegetation and the outside world. As an important characteristic parameter of crop population structure, leaf area index can quantitatively describe the photosynthesis, respiration, and transpiration of vegetation. It is widely used in the fields of environment, climate, ecology, agriculture, etc. It is defined as half of the leaf area of ​​the vegetation canopy per unit surface area. [0003] For the measurement method of leaf area index, it can be divided into direct measurement and indirect measurement. The direct measurement method is to directly measure the surface area of ​​the blade, and the reliabili...
