Oncoming car detection using lateral emirror cameras

An apparatus comprising:

• an interface configured to receive (i) first pixel data of a first field of view captured by a first capture device and (ii) second pixel data of a second field of view captured by a second capture device, wherein (a) said first capture device and said second capture device have a symmetrical orientation with respect to a vehicle and (b) said first field of view and said second field of view have an overlapping region;
• and
• a processor configured to (i) select said first capture device and said second capture device to operate as a stereo pair of cameras based on said symmetrical orientation, (ii) receive said first pixel data and said second pixel data from said interface, (iii) process said first pixel data arranged as a first plurality of video frames and said second pixel data arranged as a second plurality of video frames, (iv) detect an object located in said overlapping region, (v) perform a comparison operation on said object based on said symmetrical orientation with respect to (a) said first plurality of video frames and (b) said second plurality of video frames and (vi) determine a distance of said object from said vehicle in response to said comparison operation, wherein when said object is closer to said vehicle than said overlapping region, said processor is further configured to
• (i) perform an analysis of a plurality of video frames and
• (ii) determine said distance and a relative velocity of said object with respect to said vehicle in response to (a) said analysis and (b) a physical width that was previously measured when said object was in said overlapping region.
