Claim 6:
7. A non-transitory computer-readable medium having program code recorded thereon for range detection, the program code being executed by a processor and comprising:
program code to segment an image into one or more segmentation blobs captured by a monocular camera of an ego vehicle, in which each segmentation blob of the one or more segmentation blobs comprises a collection of pixels associated with one respective object of one or more objects in a scene surrounding the ego vehicle;
program code to perform, by a monocular camera, an autofocus operation to focus the monocular camera on pixels forming a selected segmentation blob of the one or more segment blobs based on an autofocus function value used by the monocular camera during the autofocus operation;
program code to determine, according to the focus function value received from the monocular camera, a distance to the selected segmentation blob;
program code to transmit the determined distance and subsequent determined distances to the selected segmentation blob to a downstream advanced driver assistance system (ADAS);
program code to identify, by the ADAS, an object represented by the collection of pixels forming the selected segmentation blob as a moving vehicle according to the determined distance to the selected segmentation blob received from the monocular camera;
program code to track, by the ADAS, a trajectory of the moving vehicle according to the subsequent determined distances to the moving vehicle received from the monocular camera according to subsequent autofocus function values used by the monocular camera to capture the moving vehicle; and
program code to plan and execute a change in a trajectory of the ego vehicle based on the tracking of the trajectory of the moving vehicle with the ADAS.
