Abstract

The present invention relates to a computer-implemented method for generating a bird's eye view image of a scene by using lidar information and camera image information. The method comprises steps (a) to (d). In step (a) at least one lidar frame 2 comprising points with inherent distance information and at least one camera image 3 of the scene are acquired. In step (b) a mesh representation 4 of the scene is generated by using the at least one lidar frame 2, the mesh representation 4 representing surfaces shown in the scene with inherent distance information. In step (c) a mask image 6 is generated by classifying pixels of the at least one camera image 3 as representing ground pixels or non-ground pixels of the at least one camera image 3. In step (d) the bird's eye view image 1 is generated by enhanced inverse perspective mapping and exploiting distance information inherent to the surfaces of the mesh representation 4, pixels of the mask image 6 classified as ground pixels, and the at least one camera image 3. Furthermore, the present invention relates to a system 100 and a computer program product configured to perform the method.
