Problems solved by technology

In 2012, Zhong Chu et al. published "Prediction of Sugarcane Physiological Development Time and Growth Period" in "Saccharaceae of China" by using the crop physiological development time to predict the germination period, seedling period and stem elongation period of sugarcane. The relative errors of the prediction results were 7, 3, 6, and 15 days, the prediction effect is better, and it has certain practicability, but because the growth period is twice a day, manual inspections and observations have caused certain error

Abstract

The invention discloses an automatic observation method for a sugarcane process maturing stage. The automatic observation method comprises: real-timely obtaining a sugarcane image; pre-treating the sugarcane image; segmenting the sugarcane image, and extracting the sugarcane plant image; calculating the sugarcane plant coverage FVC according to the sugarcane plant image; calculating the ratio G ofthe green pixels in the whole sugarcane plant image to the pixels in the whole sugarcane plant image according to the sugarcane plant image; calculating the ratio Y of the yellow pixels in the wholesugarcane plant image to the pixels in whole sugarcane plant image according to the sugarcane plant image; calculating the growth rate V of the sugarcane plant; and determining whether the sugarcane plant enters a process maturing stage. According to the present invention, the automatic observation method has high objectivity, high timeliness and strong practicability compared to the traditional manual observation method, and further reduces labor intensity and production cost.

Description

technical field [0001] The invention relates to the technical field of sugarcane planting. More specifically, the invention relates to an automatic observation method for sugarcane process maturity. Background technique [0002] Sugarcane is one of the most important sugarcane crops in the world, and the sucrose extracted from sugarcane accounts for more than 90% of the sugar production in my country. The development of precision agriculture is an effective measure to realize the sustainable development of sugarcane industry, and the real-time and accurate acquisition of sugarcane growth period information is one of the key foundations for the implementation of precision sugarcane industry. Through accurate observation of information such as the speed and progress of sugarcane development, it is possible to scientifically guide production activities such as irrigation, fertilization, and pest control to increase production. It can be applied to sugarcane growth models to im...
