Polluted water environment three-dimensional rapid display method and system

Abstract

The invention discloses a polluted water environment three-dimensional rapid display method and a system. The method comprises: sensing information of each water area by a corresponding sensor, and transmitting data back at regular time, storing information sensed by sensors to a database; establishing a case library in accordance with five types of the national water quality standard; dividing a water environment three-dimensional scene, and establishing a scene tree based on a BSP tree structure with a water area target knot as an organization unit; conducting view frustum culling based on a bounding volume hierarchy of the scene tree; determining the grade of water quality based on the data sensed by sensors; looking for corresponding cases in the library based on the determination result, and displaying water quality graphics; and looking for water quality information by clicking. The method and the system of the invention obviate the need for experts to observe water quality on site, realize rapid display of polluted water environment three-dimensional graphics, can conduct automatic selection of corresponding water quality graphics, and enable experts to roam in the water environment three-dimensional scene and observe, look for real-time information of current water area, and facilitate experts' research on polluted water environment.

Description

technical field [0001] The invention relates to the technical field of sensor perception information and three-dimensional visualization, in particular to a method and system for rapidly rendering a three-dimensional scene of a water-polluted environment. Background technique [0002] In the process of studying the pollution of the water environment, researchers usually conduct field sampling observations on the water environment. During the sampling process, the polluted water environment may pose a hazard to the health of researchers. At the same time, the period from on-site sampling to laboratory analysis is long, and the results obtained by the laboratory cannot represent the real-time water quality. Therefore, using sensors to monitor water quality and transmitting the monitoring data back to the control center is beneficial for experts to conduct real-time research on the water environment. However, using sensors to monitor water quality generates large amounts of da...

Problems solved by technology

However, the current viewshed culling does not target the nodes in the water environment 3D scene, nor does it use the BSP tree structure to optimize the water environment 3D scene

[0005] Due to the particularity of 3D drawing of water environment, there is currently no public fast drawing method specifically for 3D graphics of water pollution environment, using BSP tree structure, comprehensive use of technologies such as viewshed culling, case-based reasoning selection, etc. To meet the needs of quickly displaying 3D graphics of the water environment
