Embodiment Construction

[0040] figure 1 A visually assisted driving system is shown which enables precise handling of the vehicle 4 in confined environments despite the presence of dead spots reducing the driver's visibility. The vision assistance system is equipped with at least one camera 2 . Advantageously, the camera 2 is arranged at the rear and / or front of the vehicle. Preferably, the visual aid system is equipped with two cameras 2 . Preferably, the cameras 2 are arranged at the front and rear of the vehicle. According to an advantageous embodiment of the invention, the vision assistance system is provided with four cameras arranged on the four sides of the vehicle 4 .

[0041] According to an advantageous embodiment of the invention, one of the cameras 2 is mounted at the rear of the vehicle 4 , for example at the position of a sign, at the junction between the tailgate and the roof of the vehicle 4 . Where the vehicle exhibits a vertical apron extending completely at the height of the ve...

Abstract

The invention relates to an image processing method for an on-board camera 2 installed on a vehicle 4, with a view to displaying a planar aerial view for the driver, in order to assist with manoeuvres. A cumulative virtual image corresponding to an aerial view is produced from various images taken by an on-board camera while the manoeuvring vehicle is moving. The cumulative virtual image is stored in a repository that is fixed relative to the surroundings of the vehicle. An aerial image centred on the vehicle is extracted from the cumulative virtual image along a contour corresponding to the position of the vehicle. The invention further relates to a device 6 capable of implementing the method. These measures make it possible to limit the calculation operations while the images are being processed and also to minimise losses in image quality.

Description

field of invention [0001] The present invention relates to a visual assistance system for vehicle driving that uses a screen to display a view such as a top-down view of a vehicle driving environment. More specifically, the invention relates to a method for processing images from an onboard camera. More specifically, the present invention relates to a method for processing images from an onboard camera for generating a virtual image corresponding to a top-down view (eg, a vehicle-centric top-down view). The invention also relates to a device capable of carrying out the method and a vehicle comprising such a device. Background technique [0002] While the driver is operating, his field of view is reduced by the vehicle's blind spots, which prevent him from seeing his surroundings. For example, when he performs a reverse maneuver, he cannot see objects directly behind his rear bumper. In order to assist the driver, it is known to place at least one camera in a blind spot an...
