Method for object tracking at least one object, control device for carrying out a method of this kind, object tracking device having a control device of this kind and motor vehicle having an object tracking device of this kind
A method for tracking an object. A first coordinated control of a lighting device and an optical sensor is assigned to a first visible distance range. A first recording of the first visible distance range while illuminated by the lighting device is recorded with the optical sensor. If the object is detected in the first recording within the first visible distance range, a distance between the detected object and the optical sensor is determined. A second coordinated control of the lighting device and the optical sensor and an assigned, second visible distance range are determined such that the object detected in the first recording is located in a center of the second visible distance range. A second recording of the second visible distance range while illuminated by the lighting device is recorded with the optical sensor by the second coordinated control.
1. A method for tracking an object, comprising:
temporally coordinating a lighting device and an optical sensor in accordance with a first control, wherein the first control temporally coordinates the optical sensor and the lighting device so as to capture a first recording of a first visible distance range illuminated by the lighting device;
detecting the object in the first recording;
determining, based on the first recording, a distance between the object and the optical sensor; and
temporally coordinating the lighting device and the optical sensor, based on the determined distance between the object and the optical sensor, in accordance with a second control, wherein the second control temporally coordinates optical sensor and the lighting device so as to capture a second recording of a second visible distance range illuminated by the lighting device when the object is located in a center to the second visible distance range.
2. The method according to claim 1 , further comprising:
detecting the object in the second recording; and
determining, based on the second recording, the distance between the object and the optical sensor.
3. The method according to claim 1 , wherein the method for object tracking is carried out in an alternating manner for at least two different first visible distance ranges, wherein the at least two different first visible distance ranges includes: a primary first visible distance range, and a secondary first visible distance range.

capture a primary second recording of a primary second visible distance range illuminated by the lighting device when the object is located in a center of the primary second visible distance range, and
capture a secondary second recording of a secondary second visible distance range illuminated by the lighting device when the object is located in a center of the secondary second visible distance range.
5. The method according to claim 1 , wherein the at least one detected object is classified by deep learning.
6. A control device configured to:
temporally coordinate a lighting device and an optical sensor in accordance with a first control, wherein the first control temporally coordinates the optical sensor and the lighting device so as to capture a first recording of a first visible distance range illuminated by the lighting device;
