Method, device and system for measuring vertical structural parameters of vegetation canopy

Abstract

The invention discloses a method, device and system for measuring vertical structural parameters of a vegetation canopy. The measuring method includes: receiving and storing data of a calibration rod reference scale input by a user; ; Calculate the growth parameters of the vegetation to be measured in the captured image according to the calibration rod standard ruler data. When implementing the vegetation canopy vertical structure parameter measurement method of the present embodiment, the plant to be measured and the calibration rod are photographed by the photographing equipment arranged outdoors, and the photographed image is transmitted to the measuring device, and the measuring device receives the vegetation to be measured. After the image is taken with the calibration rod, the growth parameters of the vegetation to be measured in the captured image are calculated according to the data of the calibration rod reference ruler, which realizes all-weather high-frequency, unattended living body measurement, and can obtain continuous data for the same observation target for a long time, greatly The role of observational data in research and applications has been enhanced.

Description

Technical field [0001] The present invention relates to the field of plant measurement technology, and more particularly to an outdoor measurement method, apparatus, and system for planting a vertical structural parameters. Background technique [0002] The vegetation crown is the main organ of the vegetation for photosynthesis, and is an important node of Energy balance, substances and water circulation. In the fields of ecological, meteorology and agriculture, the quantitative observation of vegetation crown parameters is carried out, and the theoretical research and reality applications in the field of appeals have a pivotable role. The vertical structural parameters of the vegetation crown mainly include a leaf area index, a biomass, coverage, stem, a crown height, a height, and an area and morphology of the blade, and the plant growth state is characterized. At present, the vegetation crown parameter measures the deficiency of the leaf area index and coverage, due to the lac...

Problems solved by technology

At present, in addition to leaf area index and coverage, due to the lack of continuous observation equipment in the field, the parameters of vegetation canopy are mainly measured in two ways: sampling in vitro or manually in the field with the help of portable equipment. Indoor measurement has the advantages of comprehensive measurement parameters, and field manual assisted measurement has the advantages of quick and in vivo measurement. However, both observation methods have different degrees of disadvantages such as poor working environment and high intensity, damage to observation samples, adverse weather conditions, and even interruption of observation. As a result, the two observation methods cannot achieve the requirements of all-weather high-frequency and unattended living body measurement, which seriously restricts the long-term continuous data acquisition of the same observation target, which greatly reduces the role of observation data in research and application.
