Abstract
The utility model discloses a lane identification line detecting and alarming device. The lane identification line detecting and alarming device comprises a left charge coupled device (CCD) camera, a right CCD camera, a video decoder, a digital signal processor (DSP), a video amplifier, an audio coder, a display screen and a loudspeaker. The left CCD camera and the right CCD camera are respectively connected with the video decoder. The video decoder is connected with the DSP, one output end of the DSP is sequentially connected with the video amplifier and the display screen, and another output end of the DSP is sequentially connected with the audio coder and the loudspeaker. CCD cameras are used for collecting road information of two sides of vehicles in real time, results are output through the display screen after processing of the DSP, then whether to send alarm signals is decided according to actual conditions, and the lane identification line detecting and alarming device can assist drivers in driving effectively. Compared with the prior art, the lane identification line detecting and alarming device is higher in timeliness and accuracy, convenient to maintain, and high in reliability.
Description
Technical field
The utility model belongs to the automobile active safety field, relates in particular to a kind of Lane Mark and detects and warning device.
Technical background
Worldwide, road traffic accident causes a large amount of personal casualty and economic loss.According to statistics, there have 44% car accedent and vehicle to depart from normal lanes approximately to be relevant, its major cause is the absent minded or fatigue driving of chaufeur, cause the unconscious of vehicle to depart from, and traffic lane line detects and the function of warning device assists long-time dull driving or chaufeur maintenance vehicle excessively tired out to travel in the track just, so traffic lane line detects and the development research of warning device is significant.
Summary of the invention
The purpose of this utility model is, provides the Lane Mark that a kind of investment cost is few, real-time good, accuracy rate is high to detect and warning device.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of Lane Mark detects and warning device, comprise left CCD camera, right CCD camera, Video Decoder, DSP, the video amplifier, audio coder, read-out and loud speaker, wherein, left side CCD camera, right CCD camera are connected with Video Decoder respectively, Video Decoder connects DSP, the mouth of DSP is connected with read-out successively with the video amplifier, and another mouth is connected with loud speaker successively with audio coder.
The utility model also has following other technologies characteristics:
Described Video Decoder is the TVP5146 demoder.
Described DSP is the TMS320DM642 treater.
The described video amplifier is the OPA361 amplifier.
Described audio coder is the TLV320AIC26 coder.
Described read-out is Samsung S22A330BW telltale.
The utility model is exported the result after DSP handles, and is determined whether to send alerting signal according to actual conditions by the road information of the real-time collection vehicle of CCD camera both sides by read-out, driver assistance person's driving effectively.The utility model compared with prior art, ageing stronger, accuracy rate is higher, and is easy to maintenance, the reliability height.
Description of drawings
Fig. 1 is annexation scheme drawing of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
The specific embodiment
Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as shown in Figure 1, a kind of Lane Mark detects and prior-warning device, comprise left CCD camera, right CCD camera, Video Decoder, DSP, the video amplifier, audio coder, read-out and loud speaker, wherein, left CCD camera, right CCD camera are connected with Video Decoder respectively, and Video Decoder connects DSP, the mouth of DSP is connected with read-out successively with the video amplifier, and another mouth is connected with loud speaker successively with audio coder.In the utility model, Video Decoder adopts the TVP5146 demoder, and DSP adopts the TMS320DM642 treater, and the video amplifier adopts the OPA361 amplifier, and audio coder adopts the TLV320AIC26 coder, and read-out adopts Samsung S22A330BW telltale.
Working process of the present utility model: be installed in the road image information of two CCD camera collection vehicle fronts on the lamp of the automotive front left and right sides, convert digital signal to by Video Decoder, be transferred among the DSP then and handle.After the digital signal of DSP is handled, detect lane mark, then with signal output, through the video amplifier, drive read-out and dynamically show lane information.If the angle of judging automotive run-off-road behind the process DSP processing road image signal has the trend of run-off-road greater than the threshold value that presets, then send control signal and give audio coder; Audio coder triggers loud speaker with the signal coding back of receiving and sends alerting signal, reminds chaufeur to note the vehicle travel situations.
The electronic devices and components that the utility model adopts are known product, and those skilled in the art are according to the i.e. concrete connection mode of electronic devices and components as can be known of the technical solution of the utility model.
