METHOD AND DEVICE FOR AIDING THE NAVIGATION OF A VEHICULE

The method of assisting driving a vehicle includes constructing a digital model defining a quality index for a 3D inference image derived from an original image, the index being a function of similarity metrics defined between the original image and the 3D inference image, the construction making use of a set of observations obtained from reference 3D inference images resulting from applying 3D inference methods to a plurality of reference original images, these observations including measured values for 3D information represented on the reference 3D inference images; acquiring a first image of a three-dimensional scene that might have an influence on the driving of the vehicle; generating a 3D inference second image from the first image; estimating similarity metrics between the first and second images; evaluating the quality index for the second image by using the digital model and the estimated similarity metrics; and as a function of the quality index as estimated, a step of using the second image to assist driving the vehicle.
