Image-region is greater than the image range of Streaming Media rearview mirror screen presented, the side of being provided in the shaft of Streaming Media rearview mirror
To sensor, direction sensor differentiates the real-time azimuthal after the rotation of Streaming Media rearview mirror when Streaming Media rearview mirror rotates, then
The image that the screen of Streaming Media rearview mirror is presented switches to the opposite offset area relative to camera institute's captured image region
Domain, so that operator rotates Streaming Media camera and can be obtained the screen picture of different perspectives.
Under initial mounting state, the image range that the screen of Streaming Media rearview mirror is presented is in camera angular field of view
The heart band of position, i.e., the rotating shaft position of Streaming Media rearview mirror is placed in the middle under initial mounting state, rotates the shaft of Streaming Media rearview mirror,
Direction sensor accurately captures position both vertically and horizontally, then according to screen relative to camera angular field of view
After scale parameter is converted, screen picture switches to another area image at camera visual angle；
Direction sensor is specially gyroscope or other direction sensors, and direction sensor is when Streaming Media rearview mirror rotates
Differentiate the real-time azimuthal up and down of Streaming Media rearview mirror, realizes that image visual angle shown by the screen of Streaming Media rearview mirror is subsequent
Visor rotates and changes；
Streaming Media rearview mirror is according to direction sensor information, in institute's captured image region of the angular field of view of camera
It finds a view, reaches and traditional rear-view mirror effect up and down.
