Abstract

The invention provides a virtual simulation system for complex tasks of an intelligent system. The system is composed of a robot operation module, a virtual rendering module and a user interaction module, and a set of open source technology framework is realized. The robot operation module serves as a bottom robot operation layer and interacts with a real robot in real time through an ROS; the virtual rendering module is used as a virtual environment layer for intermediate rendering, and is developed based on an open source GIS simulation engine osgEarth to realize common simulation of a geographic information system and a robot system; the user interaction module serves as an upper user layer, interacts with a user through VR equipment, AR equipment and a virtual driving system, and is operated by a script written by the user. The system can be widely applied to aspects such as simulation and experimental planning for complex tasks of an intelligent system.

Description

technical field [0001] The invention belongs to the field of virtual simulation, in particular to a set of CyberEarth, an experimental platform for merging robot system simulation and GIS data, which is oriented to complex tasks of intelligent systems. Background technique [0002] With the development of computer technology, virtual simulation technology has gradually formed its own system, becoming the third basic method for human beings to understand the objective laws of nature after mathematical reasoning and scientific experiments, and is developing into a method for human beings to understand, transform and create the objective world. Versatile, strategic technology. [0003] Existing virtual simulation systems often focus on "imitation", and there is a problem of "imitation" but not "real". At the same time, it is difficult to achieve effective real-time interaction with multi-robot clusters in general large-scale scenarios, and the robot system and geographic infor...
