Abstract:
1. A method for determining a display image for a driver assistance system of a motor vehicle, from a plurality of measured distance values using at least one Bezier curve for representing sensed objects, which comprises the steps of: assigning the measured distance values to individual measuring lines; determining object positions of the sensed objects from given sensor positions, the individual measuring lines emanating from the given sensor positions and the measured distance values; combining adjacent ones of the measuring lines on which the object positions lie to form groups; defining object references points including a first and a second object reference point, each on one side of a respective one of the measuring lines and on a common orthogonal of the respective measuring line, for each measuring line on which an object position lies; assigning each of the individual measuring lines a sensor measuring angle having limbs that intersect a measuring boundary line at sensor edge points; and determining a respective Bezier curve for each of the groups, the respective Bezier curve running through the object positions and ending at curve sensor edge points forming two outer sensor edge points of a respective group, and reference points of the respective Bezier curve of the respective group are formed by the object reference points of the respective group.
