Abstract
The invention discloses a real-time monitoring device for vehicle rear scenes. The device comprises a first camera, a second camera, a third camera, an image synthesis module, a controller and a liquid crystal display. The first camera is arranged on a left rearview mirror and performs shooting towards the vehicle rear side. The second camera is arranged on a right rearview mirror and performs shooting towards the vehicle rear side. The third camera is mounted on a vehicle rear cover which is as high as the first camera and the second camera, and the focus of the third camera is adjusted to enable images of the three cameras to be matched according to the distance difference between the first camera and the second camera. The image synthesis module is connected with the first camera, the second camera and the third camera to synthesize the images of the three cameras. The controller is connected with the image synthesis module and selects the synthesis mode of the image synthesis module. The liquid crystal display displays and outputs the images.
Description
Technical field
The present invention relates to electricity field, particularly a kind of rear view of vehicle sight real time monitoring apparatus.
Background technology
The development of automobile has not only produced great function to social economy, and the mankind's life has also been brought to important impact.Automobile has become the main traffic instrument of people's trip, and its convenience is that aircraft, steamer and train are incomparable.
At present, the automobile pollution of China has become the first in the world, and the vehicle travelling on road is more and more, road is also more and more crowded, many chaufeurs are to the place ahead road conditions extreme care, but rear view of vehicle sight is had more visitors or business than one can attend to, and tend to occur the unnecessary accident that scratches.
How to widen the visual range of rear view of vehicle, strengthening drive safety is current problem demanding prompt solution.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes a kind of rear view of vehicle sight real time monitoring apparatus.
Technical scheme of the present invention is achieved in that
A rear view of vehicle sight real time monitoring apparatus, comprising: the first pick up camera, is arranged on left side back mirror, and takes to vehicle rear-side; The second pick up camera, is arranged on right rear, and takes to vehicle rear-side; The 3rd pick up camera, is arranged on the rear cover of vehicle with the same height of the first pick up camera and the second pick up camera, and the focal length of the 3rd pick up camera mates according to adjusting to three camera reviews with the range difference of the first pick up camera and the second pick up camera; Image synthesis unit, is connected to described the first pick up camera, the second pick up camera and the 3rd pick up camera, and the image of three pick up cameras is synthesized; Controller, is connected to described image synthesis unit, and the synthesis model of image synthesis unit is selected; Liquid crystal display, shows output to described image.
Alternatively, described synthesis model comprises two kinds: the first is parallel output pattern, and the image of three pick up cameras appears at three zonings of liquid crystal display simultaneously; The second is continuous wave output pattern, and the image of three pick up cameras synthesizes the continuous image of a width and exports on whole liquid crystal display.
The invention has the beneficial effects as follows: by three pick up cameras, the sight of rear view of vehicle is reduced completely, be presented in the visual range of chaufeur front side, expanded the visual field of chaufeur, improved travel safety.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the control block diagram of a kind of rear view of vehicle sight of the present invention real time monitoring apparatus.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Many chaufeurs are to the place ahead road conditions extreme care, but rear view of vehicle sight is had more visitors or business than one can attend to, and tend to occur the unnecessary accident that scratches.
The present invention reduces the sight of rear view of vehicle completely by three pick up cameras, is presented in the visual range of chaufeur front side, has expanded the visual field of chaufeur, has improved travel safety.
As shown in Figure 1, a kind of rear view of vehicle sight real time monitoring apparatus of the present invention, comprising: the first pick up camera 11, is arranged on left side back mirror, and takes to vehicle rear-side; The second pick up camera 12, is arranged on right rear, and takes to vehicle rear-side; The 3rd pick up camera 13, is arranged on the rear cover of vehicle with the same height of the first pick up camera and the second pick up camera, and the focal length of the 3rd pick up camera mates according to adjusting to three camera reviews with the range difference of the first pick up camera and the second pick up camera; Image synthesis unit 20, is connected to described the first pick up camera, the second pick up camera and the 3rd pick up camera, and the image of three pick up cameras is synthesized; Controller 30, is connected to described image synthesis unit, and the synthesis model of image synthesis unit is selected; Liquid crystal display 40, shows output to described image.
Preferably, described synthesis model comprises two kinds: the first is parallel output pattern, and the image of three pick up cameras appears at three zonings of liquid crystal display simultaneously; The second is continuous wave output pattern, and the image of three pick up cameras synthesizes the continuous image of a width and exports on whole liquid crystal display.
Preferably, described controller is dsp processor.
Above-mentioned dsp processor can be TMS320F2812DSP, is 32 fixed DSPs, and the AD data acquisition that it has EVA, EVB task manager and supporting 12 16 passages, has abundant Peripheral Interface, as CAN, SCI etc.The ADC module of TMS320F2812 is 12 bit resolutions, has the A and D converter of pipeline organization, the built-in dual-sampling hold circuit of TMS320F2812, and while keeping data acquisition, window has independently pre-calibration to control.And permission system is to same Channel-shifted repeatedly, allow user to carry out over-sampling algorithm, this more traditional single transformation result has increased more solution, is conducive to improve the precision of sampling.There are a plurality of trigger sources can start ADC conversion.Fast speed transfer time, ADC clock can be configured to 25MHz, and the highest sampling bandwidth is 12.5MSPS.While building data acquisition system with TMS320F2812, needn't external ADC, avoided complicated hardware design.
The present invention reduces the sight of rear view of vehicle completely by three pick up cameras, is presented in the visual range of chaufeur front side, has expanded the visual field of chaufeur, has improved travel safety.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
