Disclosed herein is a computing system for implementing a physics-based model, including a physics-based model configured to describe a physical complex system and perform deductive inference, and at least one processor. The at least one processor is configured to receive first data obtained such that the state information of first nodes is included therein in association with at least one of the passage of time and spatial distribution, to identify the state information for each of the first nodes in the physics-based model based on the first data in association with at least one of the passage of time and spatial distribution, and to determine parameters between variables in the physics-based model so that the state information can be reproduced for each of the first nodes in association with at least one of the passage of time and spatial distribution.

Provided is an integrated-system simulation system obtained from a simulation system having a command, control, and communication (C3) system of systems (SoS). The integrated-system simulation system includes an abstracted command and control (C2) model including a traffic model including inter-node traffic information transferred according to time, a mobility model including position information of nodes, and an interface model making the traffic model and the mobility model interoperate, and a communication (C) model configured to be combined with the abstracted C2 model so as to interact with the abstracted C2 model in a full-duplex manner. The abstracted C2 model is generated by acquiring traffic and mobility data between the C2 model and the C model of the SoS simulation system, hypothesizing a form of the abstracted C2 model, and learning the traffic and mobility data acquired from the SoS simulation system and determining variables of the abstracted C2 model form.

The present invention relates generally to interpolation methods for automatic generation of an accurate digital elevation model, and more particularly relates to intelligent interpolation methods for accurate extraction of 3-dimensional digital elevation models from satellite images, aerial photographs, or land surveying. The present invention is composed of three basic processes: The first process ( ) of COG/ECI elimination, the second process ( ) of hole-fill segmentation, and the third process ( ) of noise-remove segmentation. The invention produces an accurate digital elevation model even for the areas with open boundaries such as the sea off the coast and over a river.

Intelligent interpolation methods for automatic generation of an accurate digital elevation model

This invention provides a method to transform 3D object points onto 2D image points for linear pushbroom images. The problem is decomposed to the problem of finding sensor line coordinates and the problem of finding sensor column coordinates from linear pushbroom collinearity equations. The procedures to solve the problem are as follows. First, assume an initial value for image line coordinate to be sought for and using this value, calculate the sensor attitude. Next, assume the sensor attitude is constant and calculate a new image line coordinate satisfying linear pushbroom collinearity equations. Next, update the initial value with the image line coordinate calculated and continue the procedures until the difference between an initial value and a new value calculated becomes smaller than a threshold. If the different between an initial value and calculated value is smaller than a threshold, accept the calculated value as the sensor line coordinate. After finding the sensor line coordinate, calculate the sensor column coordinate satisfying linear pushbroom collinearity equations.
