Abstract

The invention relates to a crop canopy structure information automatic measurement device and a measuring method. The device includes a first supporting rod, a power supply and data processing module, a push rod, a rotary plate, a first image sensor, a second image sensor and a solar radiation sensor, wherein the power supply and data processing module is arranged at the lower part of the first supporting rod; the push rod is positioned on the first supporting rod and can move up and down along the first supporting rod; the rotary plate is arranged on the first supporting rod and above the push rod, and can move up and down with the push rod and rotate around the first supporting rod; the first image sensor and the second image sensor are arranged on the rotary plate; the solar radiation sensor is arranged on a second supporting rod extending upwards from the rotary plate. The device provided by the invention can automatically and continuously acquire information about the crop canopy interior under the outdoor field light condition, and can realize data remote collection and remote access.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to an automatic measurement device and measurement method for crop canopy structure information. Background technique [0002] The crop canopy is the most direct and active interface layer that interacts with the external environment, and has an important impact on the exchange of material and energy in the ecosystem, biodiversity, and climate change (interception of solar radiation, wind speed, air temperature and humidity, soil evaporation, soil temperature, etc.). The study of the internal information of the crop canopy is an important basis for understanding the ecological pattern and physiological and biochemical operation mechanism of the crop system. [0003] Among the published patents, the application number: 201410252049.6 discloses "an automatic measurement device for obtaining the structural parameters of the vegetation canopy", which uses a low-cost imaging system...
