摘要： A method for detecting optical defects within a windshield. The method takes, as input, a digital image map of the intensity of optical power of a windshield, and provides, as output, a digital image map of optical defects. The method includes (a) an image processing of the digital image map of optical powers for detecting and delimiting regions that differs in intensity of optical power; (b) computing, for each detected regions, a representative geometric distance and a representative value of the optical power; (c) computing an image map of the detected regions for which the product between the representative geometric distance and the representative value of the optical power is equal or superior to 2.9·10−4.

摘要： 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.

摘要： A method of analyzing the optical quality of a region of a glazing, the region being intended to be placed in front of an acquisition or measurement device such as a camera based on apparent displacements of image points. There is also provided a method of calibrating a camera based on the analysis method and to a glazing thus analyzed.

摘要： A method for measuring the optical quality of a given region of a glazing of a road or rail vehicle, the region being intended to be positioned in the optical path of an image-acquiring device, the measuring method being implemented by a measuring device including an emitter and a wavefront analyzer, the measuring method including emitting, with the emitter, a beam of light rays in the direction of the given region, analyzing, with the wavefront analyzer, the wavefront of the light rays transmitted by the given region, including generating a wavefront-error map, and determining, on the basis of the wavefront-error map, at least one optical-defect map, of any optical defects present in the region of the glazing.

摘要： A method for measuring the optical quality of a delineated region of a glazing, the delineated region being intended to be placed in front of an acquiring or measuring device such as a camera. The method is particularly suitable for measuring the optical quality of a delineated region of a transportation-vehicle glazing, such as an airplane or automobile windshield, in front of which an optical device for recording images or a device for measuring the environment outside the vehicle is placed with a view to enabling operation of an advanced driver-assistance system of the vehicle.
