Plant drought monitoring method, monitoring module and monitoring device

Abstract

The invention provides a plant drought monitoring method, a monitoring module and a monitoring device, and belongs to the technical field of crop meteorological automatic observation. The plant drought monitoring method comprises the following steps of: collecting plant images; processing the collected plant images, and preliminarily acquiring the drought condition of plants by combining the established image feature library; when preliminarily judging that the plants has a drought condition, acquiring a connected domain area change condition corresponding to the plants in the plant images ina first set time period, and acquiring a plant coverage change condition in a second set time period; and when the connected domain area is not increased in the first set time period and the plant coverage is not increased in the second set time period, judging that the plant has a drought condition. Compared with an existing plant drought monitoring method, the plant drought monitoring method hasthe advantages that the judgment on whether the connected domain area and the plant coverage corresponding to the plants in the plant images in the set time period are increased or not is added, andthe possibility of misjudgment on the plant drought condition is reduced, so that the accuracy of a detection result is improved.

Description

technical field [0001] The invention relates to a plant drought monitoring method, a monitoring module and a monitoring device, and belongs to the technical field of crop meteorological automatic observation. Background technique [0002] The detection and research of crop drought is of great significance to the growth of crops and national food security. [0003] The invention patent document with the authorized announcement number CN105427279B discloses a plant drought monitoring method. First, the image information of the plant is collected, processed and analyzed, and then compared with the preset drought threshold table to obtain the drought of the plant. Condition. This method uses image recognition technology for drought monitoring. Compared with manual observation, this method can realize automatic monitoring, saves the cost of manual observation and has great advantages over manual observation. However, in the process of plant growth, the impact of plant drought T...
