Abstract

A vehicle-borne camera-based observation system for monitoring areas adjacent a vehicle or passenger vehicle, such as a bus or schoolbus, is disclosed, to provide safer operation for passersby, including for children, and driver convenience. The system includes several cameras, and several monitors in a driver'"'"'s area displaying all of the fields of view from the cameras, such that each monitor may be controllable to show either the field of view of a first camera or a the field of view of a second camera, according to a driver selection or according to an automatic selection. Night vision, automatic tracking, and illumination systems are also provided.

and

the second camera is a left front camera positioned adjacent a corner of the vehicle joining the front side and the left side of the vehicle, the left front camera oriented rearward and to the left side of the vehicle.

4. The system of claim 1, wherein the system for illuminating the field of view around the vehicle further comprises an infrared illumination source provided for at least one camera of the plurality of cameras, to provide a night vision system displayed on at least one of the plurality of monitors.

5. The system of claim 1, wherein a first monitor of the plurality of monitors is operable to provide a driver selection between displaying an output of the first camera of the plurality of cameras and displaying an output of the second camera of the plurality of cameras.

6. The system of claim 1, wherein each camera of the plurality of cameras is provided with electronic circuitry to filter out excessive lighting.

7. The system of claim 1, wherein the the first camera is a forward-view camera positioned on a front side of the vehicle and the first field of view includes an area in front of the vehicle.

8. The system of claim 1, wherein each camera of the plurality of cameras is positioned and configured to break away without damaging the vehicle in response to sudden impact.

9. The system of claim 1, wherein each camera of the plurality of cameras is positioned and configured to swing and rebound in response to sudden impact.

10. A school bus-borne camera observation system for monitoring an area adjacent the school bus, the system comprising:

a plurality of cameras positioned at the school bus and operable to provide a view of areas adjacent the school bus, including in front and along the sides thereof, including a first camera positioned to have a first field of view, a second camera positioned to have a second field of view, a third camera positioned to have a third field of view, a fourth camera positioned to have a fourth field of view, a fifth camera positioned to have a fifth field of view, and a sixth camera positioned to have a sixth field of view;

a system for illuminating the areas around the school bus providing a visible range light source to improve visibility of children moving around the school bus during periods of low visibility; and

a plurality of monitors positioned in a driver'"'"'s area of the school bus and operable to display images provided by the plurality of cameras including a first monitor, a second monitor, a third monitor, a fourth monitor, a fifth monitor and a sixth monitor;

wherein at least one of the first, second, third, fourth, fifth and sixth monitors automatically switches between displaying of at least one of the first, second, third, fourth, fifth and sixth fields of view to another of the first, second, third, fourth, fifth and sixth fields of view based on operation of a control of the vehicle.

11. The system of claim 10, wherein the illumination system further utilizes infrared radiation.

12. The system of claim 10, including a control system which modifies an arrangement of images on the plurality of monitors based on whether the school bus is parked during a period when children embark or disembark from the school bus and other periods when the school bus is being driven.

13. The system of claim 10, including a processor which detects the movement of children around the school bus while the school bus is taking on or discharging the children and which depicts images of the children moving around the school bus in a color different than all other colors in the images.
