Abstract

The invention discloses a Vega-and-RTW-based real-time visual simulation platform for a photoelectric theodolite. The visual simulation method comprises the following steps of: rendering a virtual scene of the theodolite in real time; adding the required image effect to the scene in real time by using a shader programmed by a graphics processing unit (GPU); establishing a Simulink model of a theodolite tracking control system and generating a real-time simulation resolving module through the RTW; and scheduling the simulation module to drive the scene to finish simulation of the theodolite through the simulation unit. Methods for visual simulation and numerical model simulation are combined, visual driving is performed by using Vega, the image effect is added by using the shader, the simulation resolving module is generated from the Simulink model by using the RTW, and the requirement on real-time property is well met; and compared with a general semi-physical simulation platform, the purpose of training an operator can be fulfilled without accessing the visual simulation platform to an actual system; meanwhile, the theodolite tracking control system is simulated, and the simulation platform can be provided for analyzing and designing the actual system.

Problems solved by technology

The full virtual simulation is mostly used for theodolite function demonstration, and its practical value is not very great; the semi-physical simulation is mostly used for operator training, but its shortcomings are: first, it needs to be connected to the actual system in the simulation, and the cost is relatively high; The virtual scene is limited, and the simulation of the actual system tracking characteristics is lacking, so the purpose of system simulation cannot be achieved

The non-visual simulation of the photoelectric theodolite is mostly model numerical simulation. Generally, the mathematical model of each part of the system is established through Matlab / Simulink, and the characteristics of the system are analyzed and designed by numerical calculation. The accuracy of the simulation depends on the model. established, this method is widely used in system analysis and design, the only drawback is the lack of visual
