Abstract: A method and apparatus for determining a slope of a road using a side view camera of a vehicle, the method includes identifying a road image collected from a side view camera, dividing the road image into a plurality of regions, calculating a slope of a road for each of the plurality of regions based on driving lanes comprised in each of the plurality of regions, and determining a slope between the side view camera and the road using the slope of the road calculated for each of the plurality of regions.

Abstract: A learning method of generating a vector map and a method and apparatus for generating a vector map are disclosed. The learning method includes converting a first feature extracted by inputting a first modality sensed by a first sensor to a student model into a first feature vector in a bird eye view (BEV) space, converting a second feature extracted by inputting a multi-modality including the first modality and a second modality sensed by a second sensor to a teacher model into a second feature vector in the BEV space, and learning the student model to generate a vector map corresponding to the first modality by back-propagating cross-correlation loss by dimension that causes the first feature vector to replicate a cross-correlation with the second feature vector to the student model.
