Abstract

The invention relates to a rice lodging region extraction method, system and device and a storage medium. The method comprises the following steps: acquiring image information of a rice planting plot implementation region in real time; the acquired image information is processed; analyzing the spectral reflectivity of lodging and non-lodging regions of interest on the processed image information; and carrying out lodging feature extraction according to the spectral reflectance of the lodging and non-lodging interested regions. According to the method, the differences of texture information, surface temperature, spectral reflectivity and plant height of normal rice and lodging rice are analyzed through the differences of the images, and the accuracy of rice lodging area extraction is improved in combination with correlation analysis of characteristic parameters of the lodging rice and non-lodging rice; the salt-pepper phenomenon caused by lodging area extraction by using single data sources such as a high-definition camera, multispectral, hyperspectral and textural features is avoided, and support is provided for rapid and accurate rice lodging monitoring and acceleration of lodging-resistant rice breeding.

Description

technical field [0001] The invention relates to the technical field of extracting rice lodging areas, in particular to a method, system, equipment and storage medium for extracting rice lodging areas. Background technique [0002] Rice is one of China's main food sources, and its production is crucial to China's food security. Lodging is a common agricultural disaster in rice production, and it is one of the important factors that limit the high yield of rice. Lodging often leads to changes in the population structure of rice, affecting rice protein synthesis and nutrient transfer and automatic harvesting of agricultural machinery, which will have a great impact on its quality, yield and harvesting cost. Accurately obtaining the lodging situation of rice is conducive to establishing a relationship with the cultivation method, guiding breeding cultivation and production management, and providing data support for disaster control and post-disaster emergency plan formulation. ...
