Interactive sand table demonstration system and method

Abstract

The invention relates to an interactive sand table demonstration system and method. The system comprises a motion sensing device, a projecting device, a three-dimensional display module and a host system. The method includes the steps that first, system connection is completed, a sand table area is covered with a projected shadow, and the motion sensing device is used for capturing action information and space information in a set sand plate area; second, a relevant device is started, the motion sensing device acquires the space information of a sand table and transmit the space information to the host system, and after the space information is processed through the host system, contour lines are drawn on the sand table through the projecting device; third, when barriers exist above the sand table, action information and space information of the barriers are acquired; fourth, whether the barriers are relevant to changes of the space information of the sand table or not is judged, if not, cloud layer simulation is performed, a cloud layer coverage area and cloud layer thickness are included, then, different rainfalls can be formed through conversion, the rainfalls are converted into the accumulated water amount, and the accumulated water amount and the accumulated water flow speed are simulated; if yes, the space information of the sand table in the system is updated. The system and method are high in simulation accuracy and good in demonstration effect.

Description

technical field [0001] The invention relates to the technical field of disaster prevention and reduction information display, in particular to an interactive sand table demonstration system and method. Background technique [0002] In the prior art, multimedia technology has been widely used in various systems for more interactive demonstration of various system information, so that the system demonstration is more intuitive, vivid and more acceptable to users. [0003] The improvement of multimedia technology also makes it better applied in the field of disaster prevention and mitigation. With the improvement of the informatization level of disaster prevention and mitigation, people's requirements for informatization display in this field are also increasing. Not only do they hope to obtain various disaster data information in various regions when disasters occur, but also hope to be able to provide information through the prediction of information. Take measures to provid...

Problems solved by technology

However, the traditional disaster simulation and prediction system is mostly based on the two-dimensional display of information on the display. The amount of information provided is limited and the display is not intuitive enough. Some systems cannot directly import terrain change information into the system, and cannot adjust the simulation results for terrain changes. Therefore, it is often only possible to make corrections to the changes based on the personal experience of relevant experts. Experience corrections based on manual judgment often require senior experts. personally participate, but the corresponding expert resources are often not in place
