Abstract
The invention relates to a method for detecting a rolling shutter effect in images of an environmental region (9) of a motor vehicle (1) captured by an image sensor of at least one camera (4) of the motor vehicle (1) comprising a plurality of sensor lines (15), including the following steps: a) determining a first position (P1) on a sensor plane (13) of the image sensor corresponding to a feature (14) when capturing a first image and identifying a second position (P2) on the sensor plane (13) corresponding to the feature (14) when capturing a second image, b) determining a motion vector (v) characterizing a displacement of the feature (14) on the sensor plane (13) between the first position (P1) and the second position (P2), c) determining a vertical span (Δy) of the motion vector (v) characterizing a number of sensor lines (15) at least partially covered by the motion vector (v), d) detecting the rolling shutter effect based on the vertical span (Δy). I addition, the invention relates to a computing device (3), a driver assistance system (2) as well as a motor vehicle (1).
