Based on an automobile microwave radar anti-collision early warning system for video fusion, comprise radar module, video acquisition module and video fusion display terminal; Described radar module, video acquisition module and video fusion terminal are in the housing; Video fusion display terminal comprises treater, and treater connects telltale, annunciator, radar module and video acquisition module, and treater is integrated in PCB; Telltale is arranged on the side towards driver on housing, video acquisition module is arranged on the side towards road ahead on housing, arranges PCB, radar module and the support adapter plate for fixing PCB and radar module between telltale and video acquisition module.
Detachable fixing display base plate in PCB, PCB and radar module are detachably fixed on the both sides supporting adapter plate respectively.
Telltale base plate is fixed in PCB by large pillar stiffener and nut, and PCB is fixed on the side supporting adapter plate by little pillar stiffener, and radar module is fixed on the opposite side supporting adapter plate by fix screw I; Radar module is parallel with video acquisition module position.
Housing comprises protecgulum and rear housing; The protecgulum of housing arranges indicator screen, and video acquisition module is fixed on outside rear housing, towards road ahead by the permanent seat be arranged on inside rear housing; Protecgulum, support adapter plate and rear housing are connected as one by fix screw II.
Treater adopts arm processor.
Video acquisition module adopts camera.
Annunciator adopts buzzer phone.
Radar module adopts the microwave radar sensor based on 24GHz millimeter wave.
Be arranged on above automobile center console, below Windshield.
Be provided with base below housing, four angles of base are provided with adjustable support pillar.
The beneficial effects of the utility model: 1, first camera is installed toward the front, video acquisition module and radar module position are installed forward abreast, reach the object of radar and audio video synchronization, make user can clear, understand road ahead situation legibly, and video and radar data can be carried out record, be not merely " drive recorder ", and provide strong evidence for traffic accident; 2, when on the way driving, when running into night, heavy rain, dense fog, the reduction of heavy snow visbility, radar still can indicate road ahead situation, and can be presented at above read-out to chaufeur intuitively; 3, when when normal driving, especially on a highway, front vehicles is slowed down suddenly, and chaufeur may reflect not anxious or absent-minded, and annunciator can send " alarm " in the very first time, for the life security of passenger escorts; 6, exquisite system structure design can make this product adaptation various, by regulating the knob screw on adjustable support pillar, can tackle irregular automobile middle control platform, makes to install no longer difficulty.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model provides a kind of automobile microwave radar anti-collision early warning system based on video fusion, comprising:
Radar module, for the demand in automobile collision preventing, adopting the microwave radar sensor based on 24GHz millimeter wave, for detecting objects ahead, and the target data detected being sent to video fusion display terminal by CAN.
Video acquisition module, adopting camera, for gathering front video image, and the video data collected being sent to video fusion display terminal.
Video fusion display terminal, for receiving target data, target-marking (see Fig. 3) on a display screen after treatment, to chaufeur instruction front road conditions and alarm of sounding; Video fusion display terminal is real time recording radar data and video data also, as the strong evidence of traffic accident.
See Fig. 1, video fusion display terminal comprises arm processor, and arm processor connects TFT telltale, buzzer phone, radar module and camera, and arm processor is integrated in PCB.
By project organization part, radar module and video fusion display terminal are installed together, video acquisition module and radar module position are installed forward abreast, reach the object of radar and audio video synchronization, detailed construction design is see Fig. 2.Radar module, video acquisition module and video fusion display terminal are all arranged in the housing, are arranged on above automobile center console, below Windshield, make user be convenient to install; Be provided with base 1 below housing, four angles of base 1 are provided with adjustable support pillar 2; Housing comprises protecgulum 3 and rear housing 4, and attaching plug 5 is arranged on inside rear housing 4, and source switch 6 is arranged on the side outside rear housing 4; Telltale is arranged on the side towards driver on housing, video acquisition module 7 is arranged on the side towards road ahead on housing, namely indicator screen 8 is arranged on the protecgulum 3 of housing, video acquisition module 7 is fixed on outside rear housing 4, towards road ahead by the permanent seat 9 be arranged on inside rear housing 4; Between telltale and video acquisition module 7, set gradually PCB 10, support adapter plate 11, radar module 12; Telltale base plate 13 is fixed in PCB 10 by large pillar stiffener 14 and nut 15, and PCB 10 is fixed on the side supporting adapter plate 11 by little pillar stiffener 16, and radar module 12 is fixed on the opposite side supporting adapter plate 11 by fix screw I 17; Protecgulum 3, support adapter plate 11 and rear housing 4 are fixed as one by fix screw II 18.The structure design of above-mentioned exquisiteness can make this product adaptation various, by regulating the knob screw on adjustable support pillar 2, can tackle irregular automobile middle control platform.
The utility model does not need to do complicated image procossing, reduce costs, this system mainly orientates the dangerous road conditions such as rain, snow, night as simultaneously, that the one of vision field of driver is expanded, be similar to the equipment such as glass, infrared detecting set, under image procossing failure conditions, rely on radar system of the present utility model, still can risk object be detected, take alarm measure.The utility model main application is practicality in order to improve user and comfort feature, can see the target information of road intuitively from the left side of display interfaces, and target mark in video can be seen in the right at interface simultaneously.
