Abstract
A method for detecting an object in an environmental region of a motor vehicle by a camera system of the motor vehicle is disclosed. A first image of the environmental region is provided by a camera of the camera system with illumination of the environmental region using a light source of the motor vehicle such that a shadow of the object caused by the illumination is depicted in the first image. A second image of the environmental region is also provided by the camera in an inactive state of the light source, in which the illumination is omitted. Then, a subtraction image is generated by subtracting one of the images from the other image by an image processing device of the camera system. Then, an edge image is generated from the subtraction image, and the object is detected based on edges of the edge image by the image processing device.
