A sequence of images is processed to generate optical flow data including a list of motion vectors. The motion vectors are grouped based on orientation into a first set of moving away motion vectors and a second set of moving towards motion vectors. A vanishing point is determined as a function of the first set of motion vectors and a center position of the images is determined. Pan and tilt information is computed from the distance difference between the vanishing point and the center position. Approaching objects are identified from the second set as a function of position, length and orientation, thereby identifying overtaking vehicles. Distances to the approaching objects are determined from object position, camera focal length, and pan and tilt information. A warning signal is issued as a function of the distances.

This application claims the priority benefit of Italian Application for Patent No. 102016000094414, filed on Sep. 20, 2016, the disclosure of which is hereby incorporated by reference in its entirety.
Embodiments of the present disclosure relate to techniques for detecting an overtaking vehicle.
In the last decade, automotive companies have considerably invested in innovation concerning many aspects of Automatic Driver Assistance Systems (ADAS). Due to the increasing attention toward automotive smart systems, a significant effort has been expended in terms of new hardware and software equipment.
Embodiments of the present disclosure will now be described with reference to the annexed drawings, which are provided purely by way of non-limiting example and in which:
FIG. 1 shows a possible solution for an overtaking vehicle detection system to be used, for example, in a BSD system;
FIG. 2 shows a typical detection system;
In the following description, numerous specific details are given to provide a thorough understanding of embodiments. The embodiments can be practiced without one or several specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the embodiments.
Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
The headings provided herein are for convenience only and do not interpret the scope or meaning of the embodiments.
