Claim 12:
13. A system on chip for range detection, the system on chip comprising:
a segmentation blob detection module 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;
a segmentation blob focus module to perform, by a monocular camera, an autofocus operation to focus the monocular camera on the collection of 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;
a range detection module to determine, according to the focus function value received from the monocular camera, a distance to the selected segmentation blob and to transmit the determined distance and subsequent determined distances to the selected segmentation blob to a downstream advanced driver assistance system (ADAS);
the ADAS including a vehicle perception module to identify 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 and the ADAS to track a trajectory of the moving vehicle according to received 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
a trajectory planning module to plan and execute a change in a trajectory of the ego vehicle based on the determined distance to the moving vehicle and the tracking of the trajectory of the moving vehicle with the ADAS.
