Embodiment Construction

[0041]In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.

[0042] see figure 1 , is a flowchart of an image recognition-based rainfall measurement method according to an embodiment of the present application. The image recognition-based rainfall measurement method of the embodiment of the present application includes the following steps:

[0043] Step 100: collecting raindrops through a horizontally placed raindrop collection device;

[0044] In step 100, the raindrop collecting device is a flat device such as a rain plate or glass. When some tiny raindrops fall on the raindrop collection device, situations such as broken and splashed may occur,...

Abstract

The application relates to a precipitation measurement method and device based on image identification. The method includes the following steps: a, acquiring a raindrop image through a camera device;b, filtering the raindrop image by a morphological filtering algorithm, identifying the edge of raindrop, and obtaining a raindrop target area in the raindrop image; and c, calculating the area of raindrop in the raindrop target area, estimating the amount of raindrop water according to the area of raindrop, and estimating the precipitation according to the amount of raindrop water. Precipitationis measured by image identification, and the measurement accuracy of precipitation can reach 0.1mm. Moreover, there is no mechanical action in the measurement process, which is conducive to maintenance and use. The reliability and the authority of meteorological forecast are improved.

Description

technical field [0001] The application belongs to the technical field of precipitation observation, in particular to a method and device for measuring rainfall based on image recognition. Background technique [0002] Precipitation is an important meteorological element. The observation of precipitation is of great significance to the observation of meteorology, hydrology, ocean and environment, as well as to the safety of aviation and railway traffic. The rain gauge is an important instrument for observing precipitation, and its accuracy is directly related to the reliability of the measured data, especially in the effect test of artificial rainfall and meteorological scientific research, the accuracy of its measurement is particularly important. To ensure the accuracy and reliability of the rain gauge, it is very necessary to calibrate the rain gauge. [0003] The existing rain gauges mainly include the following types: [0004] 1. Artificial rain gauge: It is an instrum...
