Abstract
The invention discloses a forward camera system. The forward camera system comprises a left forward camera arranged in a lamp housing of a left side headlamp, and a right forward camera arranged in a lamp housing of a right side headlamp, wherein output signals of the left forward camera are processed through a first image identifying module; output signals of the right forward camera are processed through a second image identifying module; the output signals of the first image identifying module and the second image identifying module are gathered to an electronic optional switch; the control end of the electronic optional switch is connected to a controller; the output end of the electronic optional switch is connected to a displayer; and shooting images of the left forward camera or the right forward camera are displayed on the displayer.
Description
Technical field
The present invention relates to vehicle electronics field, refer to a kind of forward direction camera system especially.
Background technology
The development of automobile not only creates great function to social economy, also brings important impact to the life of the mankind.Automobile become people trip main traffic instrument, its convenience be aircraft, steamer and train incomparable.
China is as newly emerging economy, and become global first automobile consumption state, the vehicle guaranteeding organic quantity of current China has broken through hundred million.Car is many, and road has been blocked up, and traffic accident also gets more and more, and a lot of traffic accident is because driver is unsighted or lack experience and cause, and can avoid completely.
And between existing self-propelled vehicle visual area, there is check frequency, chaufeur can cause unnecessary traffic accident due to erroneous judgement, it is reported, China is owing to causing traffic accident to account for 30% in rear view mirror blind zone.
" blind spot " in general traveling is positioned at the one piece region of track, side near chaufeur left scapuloposterior (LScP) face.But, travel if chaufeur follows closely after large-scale goods carrying vehicle, automobile wagon or a bus, then chaufeur look after less than blind area much bigger.The situation that this sight line is subject to shutoff is likely serious potential safety hazard.Such as, chaufeur may cannot see the pedestrian got off from roadside or the vehicle edged in from both sides.
In driving conditions, the situation how avoiding front unsighted occurs, and is current auto manufacturing problem demanding prompt solution.
Summary of the invention
The present invention proposes a kind of forward direction camera system, solves the problem that the medium-and-large-sized vehicle of prior art stops front sight line.
Technical scheme of the present invention is achieved in that
A kind of forward direction camera system, comprise be arranged on left side head lamp lampshade inside left front to pick up camera and be arranged on right side head lamp lampshade inside right front to pick up camera, the left front output signal to pick up camera is processed by the first picture recognition module, the right front output signal to pick up camera is processed by the second picture recognition module, the output signal of the first picture recognition module and the second picture recognition module is pooled to electronic selection switch, the control end of electronic selection switch is connected to controller, the mouth of electronic selection switch is connected to telltale, show left front over the display to pick up camera or the right front photographic images to pick up camera.
Alternatively, described left front to pick up camera be noctovisor.
Alternatively, described right front to pick up camera be noctovisor.
Alternatively, described controller is dsp processor.
Alternatively, described controller is TMS320F2812 DSP.
The invention has the beneficial effects as follows: left front to pick up camera be arranged on the right front of head lamp lampshade inside, right side and block sight line to pick up camera to front and widen by what be arranged on head lamp lampshade inside, left side, driver can anticipation front road conditions.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the control block diagram of forward direction camera system of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Chaufeur follows closely after large-scale goods carrying vehicle, automobile wagon or a bus and travels, then chaufeur look after less than blind area much bigger.The situation that this sight line is subject to shutoff is likely serious potential safety hazard.
The present invention is left front to pick up camera be arranged on the right front of head lamp lampshade inside, right side and block sight line to pick up camera to front and widen by what be arranged on head lamp lampshade inside, left side, and driver can anticipation front road conditions.
As shown in Figure 1, a kind of forward direction camera system of the present invention, comprise be arranged on head lamp lampshade inside, left side left front to pick up camera 10 be arranged on the right front to pick up camera 20 of head lamp lampshade inside, right side, the left front output signal to pick up camera is processed by the first picture recognition module 11, the right front output signal to pick up camera is processed by the second picture recognition module 21, the output signal of the first picture recognition module 11 and the second picture recognition module 21 is pooled to electronic selection switch 30, the control end of electronic selection switch is connected to controller 50, the mouth of electronic selection switch is connected to telltale 40, show left front over the display to pick up camera or the right front photographic images to pick up camera.
Preferably, described left front to pick up camera be noctovisor, described right front to pick up camera be noctovisor.
Preferably, described controller is dsp processor, and above-mentioned controller can be TMS320F2812 DSP, 32 fixed DSPs, it has the AD data acquisition of 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 when keeping data acquisition, window has and independently calibrates control in advance.And allow system to same Channel-shifted repeatedly, allow user to perform over-sampling algorithm, this more traditional single transformation result adds more solution, is conducive to the precision improving sampling.There is multiple trigger source can start ADC conversion.Fast speed transfer time, ADC clock can be configured to 25MHz, and the highest sampling bandwidth is 12.5MSPS.When building data acquisition system with TMS320F2812, need not external ADC, avoid complicated hardware design.
Forward direction camera system of the present invention is left front to pick up camera be arranged on the right front of head lamp lampshade inside, right side and block sight line to pick up camera to front and widen by what be arranged on head lamp lampshade inside, left side, and driver can anticipation front road conditions.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
