Embodiment Construction

[0046] The schematic diagram of the hardware connection ( image 3 ), it can be seen that the present invention is mainly composed of unmanned aerial vehicle equipment, an image processor, a geographical scene visualization processor, a mechanism kinematics simulation processor and a terminal display device.

[0047] From the perspective of the functional modules corresponding to the hardware ( figure 1 and figure 2 ), when a railway accident occurs, the signal, the geographic location information of the accident site, and the vehicle model of the accident subject are first returned to the UAV device to call the image acquisition module. And the geographic latitude and longitude information is transmitted to the geographic scene visualization processor to call the 3D scene visualization module to build a 3D model of the geographic environment information of the incident location.

[0048] UAV equipment, mainly quadrotor aircraft, integrates the main functions of the image a...

Abstract

The invention discloses a railway emergency auxiliary rescue three-dimensional virtual electronic sand table system, which is used for assisting a railway accident emergency rescue department to quickly make an effective railway accident emergency rescue decision plan. The railway emergency auxiliary rescue three-dimensional virtual electronic sand table system consists of an image collecting module, an image identifying module, a three-dimensional model coupling module, a three-dimensional scene visualizing module and a mechanism kinematics simulating module. The railway emergency auxiliary rescue three-dimensional virtual electronic sand table system has the advantages that the three-dimensional scene of the train accident site is quickly reconstructed by the three-dimensional visualizing simulating module, so as to show a visual train accident three-dimensional scene sand table model, further construct various mechanism kinematics simulating modules to simulate the train accident emergency rescue, and provide the reference for the making of the train emergency accident rescue plan.

Description

technical field [0001] The invention relates to the field of three-dimensional visualization based on physical simulation and the field of railway emergency rescue, in particular to an electronic sand table for railway emergency auxiliary rescue. Background technique [0002] As a means of transportation with large capacity, high speed and high transportation efficiency, railway transportation plays a key role in the overall transportation of a country. The frequent occurrence of train collisions and derailment accidents in recent years has made the reliability of rail transportation and safety rescue and prevention measures the core issues of concern for the development of high-speed trains. According to the general characteristics of railway transportation safety accidents, such as severe injury, wide range of people involved, and large equipment damage, driving safety has always been the basic guarantee for ensuring the stability of the transportation system and maintaini...
