Method for determining a current distance and/or a current speed of a target object based on a reference point in a camera image, camera system and motor vehicle

摘要

The invention relates to a method for determining a current distance and/or a current speed of a target object (17) relative to a motor vehicle based on an image (15) of the target object (17), wherein the image (15) is provided by means of a camera of the motor vehicle, wherein characteristic features (18) of the target object (17) are extracted from the image (15) and a reference point (20) associated with the target object (17) is determined based on the characteristic features (18) for determining the distance and/or the speed, wherein the distance and/or the speed are determined based on the reference point (20) and wherein a baseline (21) is determined in the image (15) based on the characteristic features (18), which is in a transition area (22) from the depicted target object (17) to a ground surface (16) depicted in the image (15), and a point located on the baseline (21) is determined as the reference point (20).
