Virtual image can be gotten by estimating the scene and the imaging model, this method is called virtual scene imaging.This paper focuses on constructing an idea virtual scene imaging condition, effectively restrain the influence of outside surroundings, wiping off the uncontrolled errors to generate an accurate and reliable image. As the collecting system of the actual scene fall under the influence of the imaging optics system, CCD and outside surroundings, the quality of the image is impossibly very high, we should take filtrating noise and other operations to effectively pick up character point, which may generates uncertain errors. Consequently the errors form coupling, which brings many difficulties for the validation of the arithmetic. We can use virtual imaging to solve these problems.In the foundation of the orientation, dimension of the 3D object and the imaging model, simulation images can be generated. According to this antilogy the emulation flat-form of the virtual imaging is built. Making use of this flat-form the model of virtual scene can be conveniently and effectively built, circumvolving, displacement, marking and other operations to the object of the scene are realized. In order to imitate actual image collection, we plus noise, distortion to the simulation image.To validate the accuracy of the emulation image, we bridge the imaging architecture of OpenGL and Computer Vision analytic theory. Then the transition equations of two imaging processes are inferred and a set of equations are built. Several simulation images are gotten by the experiment of simulation of real camera imaging process in OpenGL. Theoretic analysis and experiment results state that the imaging simulation flat—form plays an important part in the validation of the arithmetic capability and the improvement of the vision effect of the computer emulation image.
