The IN-vehicle monitoring device based on the single camera as shown IN the figure 1 comprises a camera 1, a camera control unit 2, a vehicle body control unit 3, an engine unit 4, a combined instrument unit 5, a vehicle-mounted T-BOX unit 6, a vehicle owner mobile phone 7, a brake pedal sensor 8, a one-key starting switch 9, a vehicle speed sensor 10, a safety belt lock switch 11, a window lifting motor 12, a double-flash warning lamp 13 and a whistle horn 14, wherein the connection relation is that the brake pedal sensor 8, the one-key starting switch 9, the vehicle speed sensor 10, the safety belt lock switch 11, the window lifting motor 12, the double-flash warning lamp 13 and the whistle horn 14 are respectively connected with the vehicle body control unit 3 through hard wires, the camera control unit 2 is respectively connected with the camera 1 and the vehicle body control unit 3 through L IN buses, the vehicle body control unit 3 is respectively connected with the engine unit 4, the combined instrument unit 5 and the vehicle-mounted T-BOX unit 6 through CAN buses, and the vehicle owner mobile phone 7 is connected with the vehicle-mounted T-BOX unit 6 through a mobile.
The camera 1 and the camera control unit 2 are installed at the upper part of the front part in the vehicle (namely the position of an interior rearview mirror of the existing vehicle), the camera 1 is used for collecting image information and sending the image information to the vehicle body control unit 3, the camera 1 has multiple shooting modes, and the camera control unit 2 is used for adjusting the shooting modes and the rotation angle of the camera; the invention can carry out electronic focal length adjustment and a camera with an angle adjustment function similar to a fish eye, so that the camera has a close-focus shooting mode, a wide-angle shooting mode and an interval wide-angle shooting mode which can carry out angle adjustment, and the invention can achieve multiple functions (such as vehicle owner authentication, safety belt detection function and passenger distress function) by only using 1 camera, thereby realizing the camera fusion technology.
The working principle of the invention is as follows:
the vehicle body control unit 3 judges the current scene of the vehicle (such as preparation for driving, in-driving and end of driving) according to the states of the engine unit 4, the brake pedal sensor 8 and the vehicle speed sensor 10; and different shooting modes and angle adjusting instructions are sent to the camera control unit 2 according to different scenes of the vehicle, and the camera control unit 2 controls the camera 1 to switch the shooting modes and adjust the angle. The method comprises the following specific steps:
when the vehicle body control unit 3 judges that the scene of the vehicle is a standby vehicle, a close-focus shooting mode and a left α (for example, 45 degrees) angle instruction are sent to the camera control unit 2, and the camera 1 executes the close-focus shooting mode of shooting at a left α angle.
When the vehicle body control unit 3 judges that the scene of the vehicle is in driving, the wide-angle shooting mode and left α and centering and right β (for example, 45 degrees) angle circulation instructions are sent to the camera control unit 2, and the camera 1 executes the wide-angle shooting modes of the three angle circulation shooting.
When the vehicle body control unit 3 judges that the scene of the vehicle is the driving end, the interval wide-angle shooting mode and the left α and right β angle circulating instructions are sent to the camera control unit 2, and the camera 1 executes the interval (for example: 20 s) wide-angle shooting mode of the three angle circulating shooting so as to save the electric quantity of the storage battery.
The following description will be made of an example in which an angle α is 45 °, an angle β is 45 °, an angle Ckm/h is 3km/h, as is 20s, and bcm is 5cm, and the present invention can realize an owner authentication function, a seat belt detection function, and a function of asking for help when a passenger is trapped:
as shown in fig. 2, the logic of the owner authentication is:
when the driver is ready to drive, the vehicle is first unlocked and then ready to start the engine unit 4. When the brake pedal is pressed down, the brake pedal sensor 8 detects the position information of the brake pedal and transmits the information to the vehicle body control unit 3, and the vehicle body control unit 3 wakes up the camera control unit 2 and sends a close-focus shooting mode of shooting 45 degrees left. The camera control unit 2 wakes up the camera 1 and sends a close-focus shooting mode instruction for close-to-left 45 ° shooting. The camera 1 starts a close-focus shooting mode for shooting at 45 degrees left, and automatically focuses the face of a driver on the left side. The camera 1 transmits the shooting content to the camera control unit 2, and the camera control unit 2 analyzes and compares the video image with the vehicle owner. The camera control unit 2 sends the comparison result to the vehicle body control unit 3, when the driver presses the one-key starting switch 9, if the driver is the vehicle owner, the vehicle body control unit 3 starts the engine unit 4, and if the driver is not the vehicle owner, the engine unit 4 is not started, and shooting is performed on the driver again.
Referring to fig. 3, the logic of seat belt detection is:
when the driver is driving, the engine unit 4 is started, and the vehicle speed sensor 10 sends vehicle speed information to the vehicle body control unit 3. When the vehicle speed is greater than 3km/h, the vehicle body control unit 3 sends a wide-angle shooting mode instruction of cyclic shooting at three angles (45 degrees left, 90 degrees middle and 45 degrees right) to the camera control unit 2, the camera control unit 2 controls the camera 1 to start the wide-angle shooting modes of the cyclic shooting at the three angles, and the camera 1 starts the wide-angle shooting modes of the cyclic shooting at the three angles and shoots a wide-angle video in a carriage. The camera 1 transmits the shooting content to the camera control unit 2, and the camera control unit 2 analyzes the video image to obtain the riding condition of people in the vehicle. If the seatbelt buckle switch 11 of the passenger seat is not turned off, the vehicle body control unit 3 sends a warning message to the combination meter unit 5, and the combination meter unit 5 sends a warning that the passenger in a certain seat is not fastened. When the occupant fastens the seat belt, the seat belt buckle switch 11 is turned off, and the combination meter unit 5 no longer displays the occupant non-fastening warning. If the vehicle speed is less than or equal to 3km/h, the vehicle body control unit 3 does not send any control instruction to the camera control unit 2.
As shown in fig. 4, the logic of the trapped passenger asking for help is:
when the vehicle is stopped, the driver turns off the engine unit 4, and after the vehicle is locked, the vehicle body control unit 3 starts a delayed power-off program. The vehicle body control unit 3 sends 20s interval wide-angle photographing mode instructions of cyclic photographing at three angles (45 degrees left, 45 degrees center and 45 degrees right) to the camera control unit 2, and the camera control unit 2 controls the camera 1 to start the 20s interval wide-angle photographing mode of cyclic photographing at the three angles. The camera 1 starts a 20s interval wide-angle shooting mode of three angle cyclic shooting, 3 pictures in the car at the left 45 degrees, the middle 45 degrees and the right 45 degrees are respectively shot at intervals of 20s, and the camera control unit 2 analyzes the pictures to obtain the condition of passengers in the car. If the person is in the vehicle, the vehicle body control unit 3 executes a distress program, and the window glass of the vehicle is lowered by 5cm by the window lifting motor 12, so that the person in the vehicle is ensured to breathe; the double-flash warning lamp 13 is turned on to attract passersby to rescue; the horn 14 for whistling is turned on to attract passersby to rescue; the vehicle body control unit 3 sends the information that the passengers in the vehicle are trapped to the vehicle-mounted T-BOX unit 6, the vehicle-mounted T-BOX unit 6 sends distress information to the vehicle owner mobile phone 7, and the vehicle owner mobile phone 7 receives the information that the passengers in the vehicle are trapped. Finally, the vehicle body control unit 3 closes the delayed power-off routine. If no passenger is in the vehicle, the power-off delaying program is automatically closed after continuing for 20M.
