Abstract
A driving simulation apparatus includes an input unit that receives an input of an operation instruction, a vehicle simulation unit that calculates a position and an orientation of a vehicle in a virtual environment in real-time, a camera state calculation unit that calculates a viewpoint position and a viewing direction of a on-vehicle wide-angle camera based on the position and the orientation of the vehicle, and a wide-angle camera simulation unit. The wide-angle camera simulation unit includes an intermediate image rendering unit that generates multiple intermediate images by, for multiple intermediate projection planes that cover a given field of view from the on-vehicle wide-angle camera, performing perspective projection on the virtual environment from the viewpoint position and the viewing direction of the on-vehicle wide-angle camera, and a video rendering unit that generates a on-vehicle wide-angle camera video by deforming and compositing the intermediate images based on a parameter generated based on a lens characteristic of the on-vehicle wide-angle camera that has been recorded in advance.
