A method for simulating the influence of the optical power of a windshield on the image recording quality of a digital image recording device, in particular from a digital image recording device of an advanced driver assistance system. It is based on an adapted random ray tracing method to emulate the influence of the optical distortions of the windshield on the image recording quality of the digital image recording device from the measured optical quality functions of the windshield relating to these optical distortions and the image of the landscape that may be to be recorded by the digital image recording device. Considering its intrinsic optical characteristics, it provides a simulated image of the image viewed through the windshield. The method may be used in a process for evaluating the optical quality of a windshield for 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 a dig
