Abstract:
To increase the reality of a virtual camera in sensor simulation,this paper proposes a camera simulation method based on a linear calibration model.The method derives simulation camera parameters from calibration parameters to establish relationship between virtual cameras and real cameras,enables simulation to be performed on a hardware accelerating pipeline.Moreover,by introducing bump mapping and multi-pass rendering technology,the method is able to simulate linear and non-linear len distortion,enhancing the reality of simulations.The experimental results prove that the method can not only generate simulation results highly similar to the results from a real camera but also simulate various distortions with high frame rates and is effective for real-time simulation system.
