Method for detecting and validating objects from a sequence of images from a monocular vehicle camera, comprising the steps of: a) recording a sequence of images using the monocular vehicle camera, b) detecting a potential collision object in at least one image, c) ascertaining corresponding features in two consecutive images in the region of the detected potential collision object, d) calculating homographies for the ascertained corresponding features for assigning these corresponding features to a plane in space, e) assigning a plurality of ascertained corresponding features to in each case one plane in space, wherein possible spatial planes which are specified are: a bottom plane perpendicular to the y-axis, a rear wall plane perpendicular to the z-axis and a side wall plane perpendicular to the x-axis, with the z-axis extending in the longitudinal direction of the vehicle, the y-axis extending in the horizontal direction and the x-axis extending in the vertical direction, f) assigning them to that plane in space which results in the smallest back-projection error for the ascertained corresponding features, wherein the back-projection error indicates the difference between the measured correspondence of a feature in two consecutive images and the correspondence of the feature predicted from the calculated homography, and g) validating an object as a potential collision object if the plane to which the plurality of ascertained corresponding features are assigned corresponds to a rear wall plane or a side wall plane, and the back-projection errors of the rear wall plane homography and side wall plane homography are smaller than the error of the bottom plane homography, which indicates that the validated potential collision object corresponds to a raised object. a) recording a sequence of images using the monocular vehicle camera, b) detecting a potential collision object in at least one image, c) ascertaining corresponding features in two consecutive images in the region of the detected potential collision object, d) calculating homographies for the ascertained corresponding features for assigning these corresponding features to a plane in space, e) assigning a plurality of ascertained corresponding features to in each case one plane in space, wherein possible spatial planes which are specified are: a bottom plane perpendicular to the y-axis, a rear wall plane perpendicular to the z-axis and a side wall plane perpendicular to the x-axis, with the z-axis extending in the longitudinal direction of the vehicle, the y-axis extending in the horizontal direction and the x-axis extending in the vertical direction, f) assigning them to that plane in space which results in the smallest back-projection error for the ascertained corresponding features, wherein the back-projection error indicates the difference between the measured correspondence of a feature in two consecutive images and the correspondence of the feature predicted from the calculated homography, and g) validating an object as a potential collision object if the plane to which the plurality of ascertained corresponding features are assigned corresponds to a rear wall plane or a side wall plane, and the back-projection errors of the rear wall plane homography and side wall plane homography are smaller than the error of the bottom plane homography, which indicates that the validated potential collision object corresponds to a raised object.
