Generating or updating a digital representation of a trajectory, self-localization of an ego-vehicle and guiding an ego-vehicle at least in part automatically

Abstract

Described is a method for generating or updating a digital representation of a trajectory in a predefined spatial region. For each time instance while driving a capturing vehicle along the trajectory, a camera image of an environment of the capturing vehicle is captured by a camera of the capturing vehicle. A feature descriptor of the respective camera image is determined. A two-dimensional pose of the capturing vehicle in a coordinate system of the digital representation is determined depending on the camera image, and an altitude of the capturing vehicle is determined. A respective dataset of the digital representation, which includes the respective feature descriptor, the respective pose of the capturing vehicle, and the respective altitude of the capturing vehicle is generated or updated.

Dependencies are inferred from the claim text.
