Abstract
The invention discloses a method for splicing four screens to realize three-dimensional view simulation and relates to the field of the three-dimensional view simulation. The method solves the problems that the conventional simulation technology has a poor simulation effect and cannot realize full-view simulation and simulation equipment is expansive. The method comprises the following steps of: carrying out edge seamless splicing on four rear projection screens to obtain a cuboid screen; putting four projectors outside the cuboid screen for projecting simulated views to each screen; displaying scenes on the four screens in real time by using two servers; providing external synchronous signals for the two servers by using a computer; and driving a model by using Vega software, constructing the simulated views, establishing four observers, and respectively observing the scenes on the four screens from four directions to realize the full-view simulation. The method realizes the full-view simulation and expands a simulation view field. The simulation equipment of the invention is simple and low in cost.
Description
technical field [0001] The invention relates to the field of three-dimensional visual simulation, in particular to a method for realizing three-dimensional visual simulation by splicing four screens. Background technique [0002] With the continuous development of simulation technology, the fidelity of simulation visual effects and the openness of simulation vision have become the focus of current attention. The most popular screen combination methods are wide screen, ring screen and dome screen. The wide screen can expand the field of view, but it will lose a certain degree of realism; the ring screen can not only expand the field of view but also increase the realism, but it cannot realize the panoramic simulation; Simulation, but due to the need to introduce an image fusionsystem, its cost has risen sharply, and it cannot be widely promoted. Therefore, there is an urgent need for a method that is not only cheap, but also satisfies the fidelity of the simulation visual e...
