example

[0044] 1. Experimental standard material: potted rice in the filling period, with a total of 2830 samples

[0045] Manual measurement method: The method of manual measurement of plant height is to manually gather the leaves, straighten and measure the height. The measurement method of the number of tillers is to separate the rice plants and count them one by one. Ten people work together to measure, work 8 hours a day, and can measure about 280 pots a day . see results Figure 8 , Figure 9 and Figure 10 .

[0046] Put the potted rice on the trolley of the conveying line at the input end, along the figure 2 Run in the direction of the medium and large arrow, and operate according to the above method.

[0047] Finally, the total running time is 16 hours (working 8 hours a day, taking two days), an average of 20s / plant, the average absolute error of manual and systematic measurement of plant height is 19mm, and the relative error is 2.4%. Manual measurement and system mea...

Abstract

The invention relates to a fully-automatic nondestructive high-flux measurement system and a fully-automatic nondestructive high-flux measurement method for phenotype parameters of potted rice. The measurement system is controlled by a programmable controller, a conveying line conveys the potted rice, an X-ray imaging system shoots a rice tomography image, a three-dimensional visible light imaging system shoots a visible light image, a work station processes the obtained images, and all parameters of the rice are obtained. A new method for determining rice tiller number by X-ray tomography imaging is implemented, all parameters are extracted and integrated in a system, and a first set of fully-automatic, high-flux, multi-parameter and high-precision potted rice phenotype parameter automatic extraction system is successfully established.

Description

technical field [0001] The invention relates to machine vision detection technology, in particular to a measurement system and method for measuring phenotypic parameters of potted rice. Background technique [0002] In today's agricultural engineering disciplines, crop breeding is one of the hot research fields, and the study of crop breeding is inseparable from the measurement and analysis of various phenotypic parameters during the entire growth period of crops. While analyzing the phenotype, linking plant growth and development, genetic variation, environment and other aspects can provide valuable information for crop breeding, and at the same time provide a powerful tool for improving plant type and management. [0003] Rice is one of the main food crops in the world. According to the 2009 World Food Summit report on food security, by 2050, a 70% increase in food is needed to meet population growth. China is the world's largest rice consumer, and the demand for rice is ...
