Problems solved by technology

However, the current emergency system framework is mostly in the form of "database + data display". This framework cannot obtain disaster information in real time and display it dynamically, especially in the field of geological disasters to display changes in terrain and landforms caused by geological disasters. No real-time update display yet

Embodiment Construction

[0053] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0054] The present invention provides a multi-agent-based emergency disaster situation display method, which includes the following steps:

[0055] Step 1: Obtain remote sensing images for the disaster area to be displayed, and use the Scale Space Hierarchical Clustering (SSHC) algorithm to establish a multi-scale classification model of the area to be displayed. Among them, the establishment process is: using the image resolution as the scale γ of the SSHC algorithm, using the SSHC algorithm to start the cluster calculation of the remote sensing image from the specified highest resolution, adjusting the resolution, which is the scale parameter, until finally converging to a cluster point, Thus, a hierarchical clustering tree that converges with scale parameters is formed, that is, a multi-scale classification model.

[0056] In this step, starting from t...

Abstract

The invention discloses an emergency disaster situation display system and an emergency disaster situation display method based on multiple intelligent bodies, which can obtain disaster information in real time and can realize dynamic and multi-granularity three-dimensional display. The method comprises the following steps of: utilizing an SSHC (Scale Space Hierarchical Clustering) algorithm to process a remote sensing image to establish a hierarchical clustering tree; taking each node in the hierarchical clustering tree as a class; setting a surface feature corresponding to each class and establishing a three-dimensional model of each class; when a disaster situation is displayed, receiving a user instruction, wherein the user instruction comprises an expectedly-displayed surface feature A appointed by a user, and finding the expectedly-displayed surface feature A in the hierarchical clustering tree to be taken as a sub-tree of a tree root; creating collection intelligent bodies to collect data of bottom layer nodes in the sub-tree; creating organization intelligent bodies to collect data of other grades of the nodes except the bottom layer nodes from the collection intelligent bodies or the other organization intelligent bodies; rendering each type of the three-dimensional model according to the data of each node to form a three-dimensional geographic pattern of the surface feature A and displaying the three-dimensional geographic pattern; and displaying the three-dimensional geographic pattern with thinner granularity in the surface feature A.

Description

Technical field [0001] The invention belongs to the field of three-dimensional situation display, and relates to a multi-agent-based emergency disaster situation display method and system. Background technique [0002] Disaster emergency refers to the establishment of a process from dynamic display of disasters, disaster evaluation to the final formulation of emergency plans based on disaster knowledge, using database technology, geographic information system technology, and the corresponding relationship between causal analysis and decision-making. In order to effectively protect the safety of people’s lives and property and reduce economic losses, my country began to gradually develop disaster-oriented emergency system research as early as the early 1990s. The continuous development of space technology, information technology, and virtual reality technology has brought new development trends to disaster emergency systems: First, the use of various monitoring satellites and UAVs...
