Abstract

The invention provides an intelligent water level monitoring method based on image recognition. The intelligent water level monitoring method comprises: receiving image data sent by camera equipment in a tested area; detecting and identifying a water gauge part above the water surface in the image data by adopting a deep neural network, and segmenting a water gauge image above the water surface byadopting a graph cut algorithm on the basis; calculating the height of the water gauge above the water surface according to the segmented water gauge image, and obtaining the height of the water gauge below the water surface in combination with the overall height of the water gauge; the water level value can be calculated by acquiring the height of the bottom of the water gauge and the height ofthe water gauge below the water surface of the actual station. According to the method, manual on-site water level survey is not needed, image acquisition is achieved in a remote mode, analysis processing is conducted locally, the water level value is calculated, the manual operation cost is greatly reduced, and the measurement accuracy is also improved.

Description

technical field [0001] The invention relates to the technical field of water level monitoring, in particular to an image recognition-based intelligent water level monitoring method. Background technique [0002] Water level observation refers to the on-the-spot measurement of the water levels of rivers, lakes and groundwater. Water level data is closely related to human social life and production. The planning, design, construction and management of water conservancy projects require water level data. Bridges, ports, waterways, water supply and drainage and other engineering constructions also require water level data. In flood control and drought relief, water level data is more important, it is the basis of hydrological forecast and hydrological information. Water level data are important basic data in the study of the relationship between water level and flow and in the analysis of river sediment and ice conditions. [0003] Usually measured with a water gauge. The w...
