Problems solved by technology

The micro-root window method can observe the root system at the same point for a long time, but many studies have shown that the compactness between the micro-root canal and the soil often changes the original growth environment of the root system, and cannot obtain the most realistic root growth state.
For shallow-rooted crops, the volume of micro-root canals is large, which will seriously affect the growth of the root system
In addition, this kind of equipment is very expensive and cannot be observed at multiple points

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings, but it does not represent the only embodiment of the present invention.

[0014] Please read figure 1 , The miniature, multi-point root system image acquisition and processing system consists of a miniature camera, LED lights, tempered glass plates, power supply and wireless modules, and image processing parts. The overall size of the miniature image acquisition system is 1.5×1.5×0.44cm 3 , volume 1cm 3 , where the distance between the upper and lower tempered glass plates is 0.44cm, fixed by bolts with a diameter of 2mm. The double-sided cameras are respectively installed in the center of the upper and lower tempered glass plates, and their directions are all facing inward, and a white reference plate with a size of 4×0.25mm is pasted at a distance of 4mm from the camera. Four multi-band LED light sources are installed on the top and bottom respectively, and the puls...

Abstract

The invention relates to a micro multi-point root image acquisition and processing system, in particular to an image acquisition and processing system which is suitable for shallow root crops and deeproot systems, and is capable of accurately obtaining and calculating the root length density, root surface area, root mean diameter and root volume information in real time and at multiple points.

Description

technical field [0001] The invention relates to a miniature, multi-point root system image acquisition and processing system, specifically a system suitable for both shallow root crops and deep root systems, capable of real-time, accurate, multi-point acquisition and calculation of root length density, root surface area, root average diameter and Image acquisition and processing system for root volume information. Background technique [0002] The root system of plants has the function of absorbing water and nutrients, fixing the root system, and affecting the yield and quality. Root morphology research is the most important content of plant nutrition and plant physiology and ecology. Achieving real-time and accurate acquisition of root morphology is the premise and key to improving water and fertilizer use efficiency and ensuring crop quality and yield in agricultural production. [0003] Due to the invisibility of crop root growth process, the acquisition and development...
