The vehicle-mounted laser night vision device has the advantages of long visual range, wide visual field and low manufacturing cost, and is convenient for the driver to observe the image.
Description
Technical field
The utility model relates to a kind of on-vehicle night vision device.
Background technology
At present, though the safety performance of automobile improves constantly, still there is very big potential safety hazard in night travel.Show that according to investigation though people have only 20% in the time of night travel usually, the ratio that gets into an accident at night is but up to 40%.Except the overtired factor of driver, also have one more chief reason be exactly that driver's the sighting distance and the visual field is restricted.In order to solve the navigating mate restricted problem of the sighting distance and the visual field of driving a vehicle night, industry personage has carried out unremitting effort, all adopted night vision system as high-grade vehicles such as BMW, benzs, but, caused it to be difficult to be applied widely because this night vision system cost is higher.In addition, the telltale installation site of existing night vision system does not meet the visual observation custom of navigating mate, causes the visual fatigue of navigating mate easily, increases traffic safety hidden danger.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of vehicle-mounted laser night vision device, and this vehicle-mounted laser night vision device visual range is far away, and the visual field is wide, low cost of manufacture, and be convenient to navigating mate observation image.
The technical scheme that the utility model adopted is: a kind of vehicle-mounted laser night vision device comprises:
Three above image-forming assemblies are separately positioned on left side, centre and the right positions of front part of vehicle, and each image-forming assembly comprises an imageing sensor and a laser generator;
Telltale;
Image processing module receives the data-signal of the multiple image that the imageing sensor of three above image-forming assemblies gathers, and the data-signal of multiple image is synthesized piece image in real time and outputs on the telltale show;
Reflectance coating is arranged on the Windshield of vehicle, the image that shows on the telltale is reflexed in the eye of navigating mate.
The utlity model has following advantage:
1. adopt the light source of LASER Light Source as imageing sensor, visual range far reaches more than the 300m, can find dangerous situation at a distance, gives navigating mate with enough dangerous situation processing times.
2. be provided with reflectance coating on the Windshield of automobile, navigating mate need not to bow and just can observe directly reflected image on this reflectance coating, thereby more meets the visual observation custom of navigating mate, is convenient to observe.
3. the utility model only needs less parts just can realize, simple in structure, cost is low.
4 adopt a plurality of image-forming assemblies to carry out image data acquiring from different orientation, and carry out data and picture mosaic by digital signal processor, microprocessor and handle, can form 180 degree scopes looks entirely, widened the visual field of navigating mate greatly, reduced because of navigating mate and do not observe the probability that the object that occurs from the side leads to a disaster.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is made and to be further specified.
To shown in Figure 3, vehicle-mounted laser night vision device of the present utility model comprises three above image-forming assemblies 1, telltale 2, image processing module 3 and reflectance coatings 4 in conjunction with Fig. 1.Wherein, three above-mentioned above image-forming assemblies 2 are separately positioned on left side, centre and the right positions of vehicle 9 front portions, and each image-forming assembly 1 comprises an imageing sensor 11 and a laser generator 12.In the embodiment shown in the figure, three image-forming assemblies 1 have been adopted.Telltale 3 is arranged in the vehicle 9.The optical image of subject forms viewdata signal and exports to image processing module 3 after carrying out opto-electronic conversion and A/D conversion by image-forming assembly 1.Image processing module 3 synthesizes the data-signal of the multiple image that the imageing sensor 11 of three image-forming assemblies is gathered in real time piece image and outputs to demonstration on the telltale 2.Reflectance coating 4 is arranged on the Windshield 91 of vehicle 9, the image that shows on the telltale 2 is reflexed in the eye of navigating mate, so that navigating mate is observed.The utility model has been owing to adopted three above image-forming assemblies 1 to carry out image data acquiring from different orientation, thereby widened the visual field of navigating mate.In addition, the utility model has adopted the light source of laser generator as imageing sensor, and visual range far reaches more than the 300m, can find dangerous situation at a distance.
In conjunction with Fig. 3 and shown in Figure 4, image-forming assembly also comprises a shell 13 and a camera lens 14, and camera lens 14, imageing sensor 12 and laser generator 11 all are arranged in this shell 13, wherein, imageing sensor 12 is arranged on the PCB circuit card 15, and camera lens 14 is arranged on the dead ahead of imageing sensor 12.The angle of divergence α of laser generator 11 is 8 °～15 °, and the angle of field β of camera lens 14 is 8 °～20 °.Adopt this structure, laser generator 11 and camera lens 14 can obtain good coupling, reach the advantage that power is little, brightness of image evenly, is deceived defectives such as angle, dark angle.
As shown in Figure 5, image processing module 3 of the present utility model comprises a digital signal processor 31 (DSP) and a microprocessor 32, and digital signal processor 31 links to each other with microprocessor 32.The data-signal of the multiple image that the imageing sensor 11 of three image-forming assemblies is gathered at first is sent to digital signal processor 31, digital signal processor 31 carries out viewdata signal processing such as automatic exposure, AWB, automatic gain, automatic bad pixel detection and deletion, noise reduction, acutance, gamma and color rectification, and the viewdata signal after will handling then sends to little processing 32.Image after microprocessor 32 is handled digital signal processor 31 again carries out pattern matrix processing and splicing, forms 1920 * 480 wideband video flowing and output on the telltale 2 to show.
