Patent US10518703
Issued 2019-12-31
Automatic Mirror Adjustment Using An In-car Camera System
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 comprising a plurality of frames based on a targeted view of a driver; 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 a vehicle, (B) said field of view is determined based on location coordinates for eyes of said driver, (C) said location coordinates for said eyes are determined based on analysis of one or more video frames of said video signal to determine 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.
- 12. An apparatus comprising:
a sensor configured to generate a bitstream based on a targeted view implemented by a video capture device, wherein said targeted view is selected to capture a driver of a vehicle; a first processor configured to (i) receive said bitstream from said sensor and (ii) generate a video signal comprising a plurality of frames based on said bitstream; and a second 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 location coordinates for eyes of said driver, (C) said location coordinates for said eyes are determined based on analysis of one or more video frames of said video signal to determine 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.
- 14. A method for adjusting mirrors of a vehicle, comprising the steps of:
(A) generating a video signal comprising a plurality of frames based on a targeted view of a driver; (B) performing analysis of video frames of said video signal; (C) determining location coordinates for eyes of said driver based on said analysis of said video frames; (D) calculating a field of view of said driver based on said location coordinates determined for said eyes of said driver; and (E) generating a control signal in response to said calculated field of view of said driver, wherein (i) said control signal is used to adjust one or more of said mirrors of said vehicle, (ii) a depth coordinate representing a distance of said eyes from a sensor is used to determine said location coordinates for said eyes of said driver and (iii) 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.
