Portable crop parameter measurement and growth vigor intelligent analysis device and method

Abstract

The invention discloses a portable crop parameter measurement and growth vigor intelligent analysis device and method. The device comprises a spectral imaging module, a laser structured light scatter emitter, a binocular photography measurement module, an image acquisition control module, a data acquisition module, a data processing module, a data analysis and application module and a battery module. The device and the method provided by the invention realize fast automatic measurement of a crop canopy structure based on a structured light measurement technology of laser triangulation range-finding principle. A laser single-point light source is converted to a specific form to serve as a light source by an optical splitter to generate evenly spaced point-like projection light sources, and the generated light beams can irradiate a measured surface. When a multispectral image is acquired, the three-dimensional coordinate or spatial form of each light spot or light bar by a photogrammetry technology, and three-dimensional reconstruction of a crop canopy structure can be realized by a spatial interpolation technology.

Description

technical field [0001] The invention belongs to the technical field of agricultural informatization, and relates to a crop parameter measurement and growth analysis device and scheme, in particular to a portable crop parameter measurement and growth intelligent analysis device and method based on the combination of laser and hyperspectral. Background technique [0002] Against the backdrop of dwindling arable land resources, serious shortage of water resources, growing population, rapidly increasing demand, and increasingly prominent environmental problems in my country, how to ensure sustainable agricultural development and food security, so that agricultural output and quality can grow synchronously with agricultural inputs, Realizing the coordinated development goals of high-yield, high-quality, high-efficiency, and ecological security in agriculture is a major problem that my country's agriculture must face and solve for a long time to come. Precision agriculture was ad...

Problems solved by technology

However, in agricultural production, measuring instruments related to the three-dimensional geometry of crops have not yet appeared in the form of portable instruments.

[0006] At the same time, the observation and analysis of three-dimensional geometric data and the observation and analysis of crop nutrients and biochemical parameters are difficult to carry out at the same time, and the simultaneous acquisition of these two types of parameters plays an extremely important role in the analysis of crop information

[0007] On the other hand, the existing agricultural parameter measuring instruments are mainly based on professional analysis, which belong to relatively professional parameters in the field of agricultural science and technology, and lack of popularization for ordinary farmers.

Due to insufficient professional scientific and technological knowledge, it is difficult for the above parameters to form a direct driving force for agricultural production

[0008] To solve the above problems, breakthroughs must be made from a technical point of view. It is necessary to integrate the two types of analysis and monitoring methods of geometry and spectroscopy, and monitor simultaneously. This technical bottleneck has not been broken through at present.

Moreover, in order to be used by farmers, it is necessary to provide real-time intelligent monitoring results of crop growth, which relies on the use of basic observation data of typical crops to form an expert support decision-making system, which cannot be accomplished in the field of single crop parameter measurement instruments
