METHOD FOR SIMULATING THE EFFECTS OF THE OPTICAL DISTORTIONS OF A WINDSHIELD ON THE IMAGE RECORDING QUALITY OF A DIGITAL IMAGE RECORDING DEVICE

WIPO Patent Application WO/2022/073807

A1

A method for simulating the effects of optical power of a windshield on the image recording quality of a digital image recording device, in particular of a digital image recording device from an advanced driver-assistance system. It is based on adapted stochastic ray tracing method to simulate the effects of the optical distortions of a windshield on the image recording quality of a digital image recording device from a measured optical quality function of the windshields related to these optical distortions and an image of a landscape likely to be recorded by a digital image recording device. It provides a simulated image of said image as viewed through said windshield taking into account its intrinsic optical particularities. The method can be used in a process for evaluating the optical quality of windshields for a use with a digital image recording device, in particular with a digital image recording device of an automated driving and advanced safety system, or in a process for calibrating digital image recording device of an automated driving and advanced safety system.
