In order to enable the required image of moveing backward that is acquired without dead angle, further, in such scheme, Preferably first photographic head and second camera are separately mounted to the top of vehicle body sided mirror unit, the Three photographic head are arranged on the position of tail of the body middle.
In such scheme, preferably reversing detection module is that automobile reverse gear detects device, main and vapour The connection of car gear device, detects whether that entrance is reversed gear in real time, when reversing, and this reverse image system Will automatically open up, put change user and move backward in time, bring convenience to user.
In such scheme, preferably distance detection module is lived by three ultrasonic distance-measuring sensor structures Becoming, one of them is arranged on the position of tail of the body middle, and two other is arranged on vehicle body both sides and leans on Tail position.
In such scheme, preferably voice module is MP3 voice module, and MP3 voice module includes Microprocessor, speech processing circuit and speaker, the input of microprocessor is connected with controller module, The outfan of microprocessor is connected with the outfan of speech processing circuit, the outfan of speech processing circuit It is connected with the input of speaker.
Advantages of the present invention with effect is:
1, the present invention use reversing detection module detect whether automobile is in state of rolling backward in real time, when When being in state of rolling backward, automatically start reverse image system by automatic switch module, it is achieved be System starts automatically, prevents car owner from forgetting to turn on camera system when reversing, can fall with convenient car owner Car；
2, further, carried out reversing automobile image by the multiple photographic head in camera module It is acquired, image processing module multiple images is carried out splicing synthesis, as long as making car owner look at one Width composograph just can well be moveed backward, and prevents car owner from observing several and has disperseed attention, Difficulty is brought to reversing；
3, invention also uses distance detection module, vehicle body and other barriers can be detected in real time Distance, and carry out voice message by voice module, prevent user's imprudence sometimes from causing vehicle body Scratched.
