Abstract

The invention discloses a river water level monitoring method based on monocular camera, which is an information processing method belonging to the video monitoring field, that is using light reflection characteristic difference between the river plane surface and the bank plane surface to determine water level height with horizontal pixel projection algorithm (HPIP) for video collected images. The method includes the steps: (1) using affine transformation for executing geometric correction to image; (2) executing histogram equalization process for video image greyscale; (3) determining water level height with horizontal pixel projection algorithm; (4) real time and robust tracking water-level fluctuation. The invention has the advantages of easy realization, strong robustness, high reliability, high real time property or the like, and can provide real time dependable information for hydrology monitoring.

Description

technical field [0001] The invention relates to a method for monitoring river water levels based on a monocular camera, in particular to a method for real-time monitoring of river water levels using video images collected by a monocular camera, and belongs to the technical field of image information processing. Background technique [0002] With the rapid development and maturity of video surveillance technology, more and more intelligent surveillance systems are used in daily life. However, computer vision technology is still a blank in river water level monitoring. As we all know, my country is a country with frequent floods, and water monitoring is the focus of the water conservancy department. In order to prevent floods and provide a large amount of reliable data and information for flood control decisions in a timely manner, it is necessary to monitor the water levels of rivers and reservoirs in real time and accurately. At present, most domestic hydrological stations ...
