METHOD FOR DETECTING AN OBJECT IN AN ENVIRONMENTAL REGION OF A MOTOR VEHICLE, DRIVER ASSISTANCE SYSTEM AND MOTOR VEHICLE

The invention relates to a method for detecting an object (12) in an environmental region (6) of a motor vehicle (1) based on a temporal sequence of images (9) of the environmental region (6), which are captured by means of a camera (3a, 3b) of the motor vehicle (1), wherein by means of an electronic evaluation device (4) of the motor vehicle (1), at least one characteristic pixel (p) of the object (12) is determined in a first image of the sequence (9) of images and the at least one determined characteristic pixel (p) is tracked in at least a second image (8) and a flow vector (´) each having a vertical component (´ v ) and a horizontal component (´ u ) is provided by the tracking, wherein a first depth component (z' 1 ), which is perpendicular to the vertical component (´ v ) and the horizontal component (´ u ), is determined based on the vertical component (´ v ), and a second depth component (z' 2 ), which is also perpendicular to the vertical component (´ v ) and the horizontal component (´ u ), is determined based on the horizontal component (´ u ), and if the first depth component (z' 1 ) corresponds to the second depth component (z' 2 ) within a tolerance range, a validated final depth component (z') of a tracked characteristic pixel (13) depending on the characteristic pixel (p) is provided.
