A system and method for the automatic cruise measurement of an unmanned ship based on the storage capacity of a reservoir

Abstract

The invention provides an unmanned ship automatic cruising measurement system and method for storage capacity of a reservoir. The system includes a front-end detection module and a back-end calculation and control module; the front-end detection module is responsible for collecting and uploading information such as water depth, latitude and longitude, and attitude angle in designated waters; Carry out quality assessment and generate supplementary survey paths, control multiple unmanned ships to automatically cruise and supplementary surveys; integrate preliminary survey and supplementary survey data to calculate storage capacity. The invention restores the underwater topography to the greatest extent through the triangular grid division method based on the minimum interior angle variance, and improves the accuracy of storage capacity measurement; it proposes a grid quality evaluation and supplementary measurement point generation method for the problem of generally low quality of preliminary exploration data , to further improve the completion of measurement data and the accuracy of storage capacity calculation; automatically generate a cruise path with balanced energy consumption according to the supplementary measurement points and control multiple unmanned ships to automatically cruise to complete the supplementary 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...
