Automatic mirror adjustment using an in-car camera system

摘要

An apparatus comprising a sensor, an interface and a processor. The sensor may be configured to generate a video signal based on a targeted view of a driver. The interface may be configured to receive status information about one or more components of a vehicle. The processor may be configured to generate a control signal in response to a determined field of view of the driver. The control signal may be used to adjust one or more mirrors of the vehicle. The field of view may be determined based on (i) the video signal and (ii) the status information.

1. An apparatus comprising:
a sensor configured to generate a video signal based on a targeted view of a driver; an interface configured to receive status information about one or more components of a vehicle; and a processor configured to generate a control signal in response to a determined field of view of said driver, wherein (A) said control signal is used to adjust one or more mirrors of said vehicle, (B) said field of view is determined based on (i) location coordinates for eyes of said driver and (ii) an orientation of said one or more mirrors, (C) said location coordinates for said eyes are determined based on analysis of one or more video frames of said video signal to determine (i) one or more of a first location coordinate and a second location coordinate of said eyes and (ii) a depth coordinate representing a distance of said eyes from said sensor, and (D) said depth coordinate is determined based on a comparison of a reference number of pixels of an object in a reference video frame to a current number of pixels of said object in said video frames.
