Problems solved by technology

Although Zhang Xuefen, Wang Xiufang and others have noticed the impact of precipitation, strong wind, heavy fog, and light on image quality, they only "eliminated" the "fuzzy" images taken under abnormal disaster weather conditions during image processing. To a certain extent, it affects the records of key nodes in the crop growth process and the process of disaster impact, reducing the accuracy and representativeness of test results

Abstract

The invention provides a crop canopy image collection method based on context awareness. The method comprises the following steps that multiple environment parameters of a crop growth area are collected; the present weather condition is determined according to the environment parameters; and according to the different weather conditions, different crop canopy image collection modes are selected to collect crop canopy images. Thus, the crop can be observed continuously and dynamically, so that researchers can master the growth node and weather change in a better way.

Description

technical field [0001] The invention relates to the technical fields of crop growth monitoring, image collection, etc., and in particular to a method for collecting crop canopy images based on scene perception. Background technique [0002] Crop canopy information (including coverage, greenness, leaf area, etc.) can comprehensively reflect the dynamic changes during the growth period of crops and characterize the growth status of crops, which is one of the important contents of crop growth monitoring in digital agriculture. [0003] At present, the research and application of digital agriculture are developing vigorously. As an important direction in the field of digital agriculture, the dynamic monitoring of crop growth has been highly valued by researchers. With the development of computer vision and graphics and image processing technology, digital image acquisition products are gradually When applied to the monitoring of crop growth process, researchers have made a lot o...
