Abstract

The invention provides a river channel monitoring device and method and a computer readable storage medium, belongs to the technical field of river channel management, and solves the technical problem of high cost of an existing river channel monitoring mode. A riverway monitoring device is used for monitoring a plurality of preset detection points provided with water gauges on a riverway and comprises a camera, a holder, an inclinometer and a CPU. The holder and the inclinometer are fixed to the camera, the holder is used for controlling the shooting position of the camera, and the inclinometer is used for detecting the inclination angle of the camera along the Y axis; the video output end of the camera is electrically connected with the input end of the CPU; the information output end of the holder and the information output end of the inclinometer are electrically connected with the input end of the CPU, and the output end of the CPU is electrically connected with the control end of the holder and the control end of the inclinometer; and the CPU controls the inclination angle of the inclinometer and the rotation of the holder, so that the camera performs video data acquisition on a plurality of preset detection points, and the CPU identifies the video data to obtain the water level, flow velocity or flow data of the river channel.

Description

technical field [0001] The present invention relates to the technical field of river channel management, and in particular, to a river channel monitoring device, method and computer-readable storage medium. Background technique [0002] With the maturity of AI intelligent recognition technology in recent years, technologies such as behavior analysis, face recognition, and license plate recognition have been widely used in video monitoring. The application of video monitoring in hydrology and water conservancy is still in the primary video monitoring stage, and AI recognition technology is still It is not widely used in water conservancy video monitoring. The monitoring of river flow velocity and water level is still the use of traditional propellers, radar current meters and radar water level meters. Using traditional detection equipment to detect river sections has limitations such as high cost and difficult construction. [0003] Therefore, the existing river monitoring me...
