Abstract

The invention discloses a novel water metering method for an open channel based on multi-point water level. The invention discloses a water level detecting method based digital image processing, wherein a traditional water gauge is used to simulate a principle that a worker gathers the water level data, so that real-time colour image data of the water gauge is acquired by a camera head; a modern intelligent digital image processing technology is used to divide out a waterline, and the practical water level data is acquired by calculating; finally, the overflowing amount in the open channel iscalculated according to a manning formula. The overflowing amount in the open channel can be quickly, simply and real-time reflected by simulating the principle that the worker gathers the water level data, and employing the camera head and the image processing software. The hardware related by the method is only the camera head and a computer, thus the installation is simple, and the maintenanceis easy.

Description

technical field

[0001] The invention belongs to the field of engineering technology, and in particular relates to a new method for measuring open channel flow based on the combination of traditional open channel hydraulic theory and modern computer computing technology. Background technique

[0002] Water-measuring equipment and water-measuring technology in irrigation areas are basic measures to realize planned water use and control the quality of irrigation water, and are necessary tools and means to implement fee-by-square and promote water conservation. The commonly used methods of water measurement in irrigation areas include: one is to use hydraulic structures to measure water, which is more economical and convenient; It is used when there is no hydraulic structure or the existing hydraulic structure cannot be used for water measurement, or when the required water measurement accuracy exceeds the accuracy that the hydraulic structure can achieve; the third is to use th...
