10. A passenger compartment monitoring apparatus comprising:
-
a rotatable room mirror arranged in a passenger compartment;
first and second imaging devices arranged on the room mirror, wherein the first imaging device has a first horizontal angle of view and a first vertical angle of view and the second imaging device has a second horizontal angle of view and a second vertical angle of view;
wherein when the room mirror is arranged so that a normal line with respect to the room mirror lies on a horizontal plane of the vehicle;
the first imaging device has a first horizontal mounting angle formed by a first horizontal projection optical axis that is obtained by projecting an optical axis of the first imaging device on the horizontal plane and a horizontal reference line that is vertical to the normal line on the horizontal plane, and the first horizontal mounting angle is set based on the first horizontal angle of view and a rotation angle of the room mirror that faces a driver seat;
the second imaging device has a second horizontal mounting angle formed by a second horizontal projection optical axis obtained by projecting an optical axis of the second imaging device on the horizontal plane and the horizontal reference line and the second horizontal mounting angle is set based on the second horizontal angle of view and the rotation angle;
the first imaging device has a first vertical mounting angle formed by a first vertical projection optical axis obtained by projecting the optical axis on the vertical plane and a vertical reference line that is vertical to the normal line on the vertical plane, and the first vertical mounting angle is set based on the first vertical angle of view;
the second imaging device has a second vertical mounting angle formed by a second vertical projection optical axis obtained by projecting the optical axis on the vertical plane and the vertical reference line, and the second vertical mounting angle is set based on the second vertical angle of view; and
wherein the first and second horizontal angle of views are set so that imaging areas of the first and second imaging devices are overlapped with each other at a predetermined distance from the room mirror. - View Dependent Claims (11, 12, 13, 14, 15, 16)
