Grid contour drawing method based on marine internet of things

Abstract

The present invention relates to a grid contour drawing method based on the marine internet of things, comprising the following steps: information interaction and collection between multi-sensors based on the marine internet, sensor data preprocessing and distributed fusion operations; The entire space of points is divided into grids; the calculation of the standard deviation and mean value is calculated for the data points in each grid, and the difference between all data points and the mean value is calculated to obtain a data list and compare each data in the list value and three times the standard deviation, if the data value is greater than three times the standard deviation, continue to cycle the grid construction in the second and third steps in this area until the requirements are met; connect the data points according to the connection rules, The entire grid space is constructed into a triangular grid, and further triangular grid division is adopted for grids with sparse data; contours are drawn according to the distribution of weights, and the next triangular grid will be searched after passing through the triangular grid until Indicates the end of contour tracing after traversing all triangular meshes; visualized.

Description

Grid contour drawing method based on marine Internet of things technical field [0001] The invention belongs to the field of marine data processing, and relates to a grid contour drawing method based on the marine Internet of Things. Background technique The research of marine environmental monitoring system has attracted more and more people's attention. Mutual plays an important role in the marine environment detection system. In order to protect and utilize marine resources, the collection and processing of marine information It is urgent. The Internet of Things mainly connects sensors and networks, and its purpose is to make objects communicate with each other. letter, achieve higher work efficiency and save operating costs. In the existing marine environment monitoring area, through the construction of multi-sensor The Internet of Things, where sensors cooperate to sense, collect and process information about objects in the network coverage area, and send infor...

Problems solved by technology

[0003] At present, the visual processing of ocean big data is not perfect at home and abroad. There is a lot of room for improvement in the contour drawing algorithm and application of factors such as temperature and pressure. Apply the contour drawing to the visual display of ocean data. Has become a hot and difficult point of current research
