Water depth measuring system and method based on water level gauge and camera

The invention discloses a water depth measuring system and method based on a water level gauge and a camera. The system comprises the following modules: a wireless digital water level gauge; a water depth value transmission module; a camera; an image transmission module; a data receiving module; a background processing module. According to the invention, the area flooding depth in a camera picture can be measured, and an area flooding isobath diagram is generated. The system can be used for evaluating the urban inland inundation condition, and provides a basis for a government decision department to formulate policies such as urban drainage, rescue and relief work, traffic control and the like. The urban area flooding condition measured by the system can also be provided for the public, and reference is provided for public travel, risk avoiding and the like. 本发明公开了一种基于水位计和摄像机的水深测定系统和方法，系统包括以下模块：无线数字水位计；水深数值传输模块；摄像机；图像传输模块；数据接收模块；后台处理模块。本发明可以测定摄像机画面内区域淹水深度，并生成区域淹水等深线示意图。本发明可以用于对城市内涝情况的评估，为政府决策部门制订城市排水、抢险救灾、交通管
