Description

Agricultural crop blade growth vision measuring device

Technical Field

The utility model belongs to the technical field of information acquisition and processing, concretely relates to agricultural crop blade growth vision measuring device.

Background

In the agricultural production process, the growth conditions of crop leaves, such as leaf area indexes, have great influence on the growth development, stress resistance and yield of crops. The existing measuring methods for the growth information of the crop leaves can be divided into two categories of direct measurement and indirect measurement.

Direct measurement methods can be divided into conventional measurement methods and instrumental measurement methods. The traditional methods comprise a coordinate paper method, a coefficient method, a paper-cutting method, a weighing method and the like; the measuring method mainly comprises a manual handheld method and a bracket scanning method. Most of the traditional methods need to pick up leaves for sampling measurement, and although the measurement principle is simple, the method is complex to operate, low in accuracy, time-consuming and labor-consuming, and easy to damage the original physiological structure and growth state of crops, so that the growth and yield of the crops are influenced. Compared with the traditional method, the leaf area meter used in the measuring method is convenient to operate and has small damage to crops, but the crop leaves are imaged and scanned mainly by manually holding the visual sensor, and due to the uncertainty of personnel behaviors and other factors, the measuring process is unstable, so that the leaf measuring result has the defects of double images, disorder, even loss and the like; the bracket type scanner mainly scans the blades in a small range by depending on the fixed position of the bracket, is inconvenient to move and poor in flexibility, and easily causes the problems of data loss and the like when the bent blades are measured.

Compared with a direct measurement method, the indirect measurement method is mainly used for measuring and modeling the growth condition of the blade by means of parameter inversion, calculation and the like, such as an optical measurement method and an oblique point sampling method. The indirect measurement method is greatly influenced by the environment, the effective working time is short, and all-weather real-time measurement is difficult to realize.

In conclusion, the research on the growth state of the crop leaves can provide effective and scientific guidance for the growth of agricultural crops, and has important significance for researching the microclimate of farmlands, the physicochemical and habitat of crops, genetic breeding, crop cultivation and controlling the group structure of crops. The existing measurement means has the defects of complex operation, damage to the growth state of crops, easiness in being influenced by the behavior of operators, serious data loss, poor flexibility and timeliness and the like. Therefore, it is very urgent to develop an automatic measuring system capable of performing all-weather accurate measurement of the growth of crop leaves.
