Unmanned ship automatic cruise calculation system and method for storage capacities of reservoirs

Abstract

The invention provides an unmanned ship automatic cruise calculation system and method for storage capacities of reservoirs. The system comprises a front-end detection module and a back-end calculation and control module, wherein the front-end detection module is responsible for collecting and uploading information such as water depth, latitude and longitude, attitude angle and the like in a designated water area; in order to improve the completion degree of measured data, the back-end calculation and control module carries out quality assessment on the measured data and generates a re-measurement paths to control a plurality of unmanned ships for automatic cruise re-measurement; and preliminary detection data and re-measured data are integrated to calculate a storage capacity. According to the system and method, the water bottom terrains are restored to the greatest extent through a minimum internal angle variance-based triangular mesh division method, so that the accuracy of the storage capacity calculation is improved; and a grid quality assessment and re-measurement point generation method is put forward for the problem that the preliminary detection data is generally low in quality, so that the completion degree of the measured data and the accuracy of the storage capacity calculation are improved; and an energy-balanced cruise path is automatically generated according tothe re-measurement points and the plurality of unmanned ships are controlled to carry out automatic cruise to complete the re-measurement task.

Description

technical field [0001] The invention relates to the field of measuring and calculating the capacity of water reservoirs, in particular to a system and method for measuring and calculating the capacity of reservoirs based on unmanned ships. Background technique [0002] Reservoirs are an important part of my country's water conservancy engineering system, with functions such as flood control, irrigation, and shipping. The water storage capacity of the reservoir is called the storage capacity, that is, the volume below the water storage level of the reservoir, referred to as the storage capacity. The monitoring of reservoir storage capacity is an important link to ensure the safety of the reservoir area, early warning of disasters, and flood control. It can also reflect changes in the amount of sediment on the bottom of the water, and is an important guarantee for channel dredging and navigation safety. [0003] Due to the generally large area of ​​the reservoir and the compl...
