Wherein, described image extraction mechanism is a full-view camera.
Wherein, described image extraction mechanism is rotating pick-up head.
Wherein, described system also comprises prompting mechanism, and described prompting mechanism connects described data processing chip and points out can't be by described stop line the time determining at described data processing chip.
Wherein, described prompting mechanism comprises loud speaker, alarm lamp.
For solving the problems of the technologies described above, embodiment of the present utility model also provides a kind of vehicle, comprises such as front each described drive assist system for traffic signal lamp.
The beneficial effect of technique scheme of the present utility model is as follows:
In the such scheme, the traffic signal lamp, the stop line location status that adopt existing image processing techniques that two cameras are extracted carry out graphical analysis, and judge that according to the speed of a motor vehicle can vehicle normally pass through stop line.The utility model can be judged by driver assistance, improves drive safety and prevents traffic accident.
Description of drawings
Fig. 1 is the structural representation for the drive assist system of traffic signal lamp of the utility model embodiment;
Fig. 2 is the workflow schematic diagram for the drive assist system of traffic signal lamp of the utility model embodiment.
The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model lacks DAS (Driver Assistant System) for traffic signal lamp for existing vehicle, cause the abundant not driver of experience to be easy to because the traffic violation that erroneous judgement causes and the problem that causes traffic accident, a kind of drive assist system for traffic signal lamp is provided, its structure comprises as shown in Figure 1: be used for extracting traffic signal lamp image and stop line image the image extraction mechanism, be used for traffic signal light condition and stop line position are carried out picture processing chip that image processes, are used for data processing chip that data are processed; Wherein said image extraction mechanism connects described picture processing chip, and described picture processing chip connects described data processing chip, and described data processing chip connects the electronic control unit (Electronic Control Unit, ECU) of vehicle to obtain current vehicle speed.
Those skilled in that art are appreciated that, owing to slightly have any different in the position that the traffic signal lamp on the current road are set, for example some is arranged on the traffic sign bar at crossing and is transversely arranged, some is fixed on the traffic sign bar in the middle of the crossing and vertically arranges, and some is fixed on the traffic sign bar on right side, crossing and vertically arranges.Therefore for image that can these traffic signal lamp of Obtaining Accurate, this image extraction mechanism comprise one at least one be used for extracting the traffic signal lamp image the first camera, at least one is used for extracting second camera of stop line site plan picture.Certainly, this image extraction mechanism also can be a full-view camera or rotating pick-up head.
Wherein, also comprise be used to the 3rd camera of getting traffic signal lamp countdown image.This is because some regional counting down device of traffic signal lamp is not set together with traffic signal lamp.For example, this inverse timing device may be to be arranged under the traffic sign lamp on footway sometimes.Certainly, when realizing the system of the utility model embodiment, can use the first camera or second camera and obtain traffic signal lamp countdown image, the utility model is not made restriction to this.
Described system also comprises prompting mechanism, and described prompting mechanism connects described data processing chip and points out can't be by described stop line the time determining at described data processing chip.In the utility model embodiment, described prompting mechanism comprises loud speaker, alarm lamp.
For solving the problems of the technologies described above, embodiment of the present utility model also provides a kind of vehicle, comprises such as front each described drive assist system for traffic signal lamp.
Described electronic control unit connects described vehicle, and described picture processing chip is used for the image that described image extraction mechanism is extracted is analyzed to extract at least traffic signal lamp image and stop line site plan picture from image; Can described data processing chip connects described picture processing chip, electronic control unit, normally pass through described stop line to judge described vehicle according to traffic signal lamp, stop line position and current vehicle speed.
In such scheme, can the system of the utility model embodiment be comprehensively judged by traffic signal light condition, stop line position, current vehicle speed, normally pass through stop line to judge vehicle.Can judge by driver assistance like this, prevent from improving drive safety and preventing traffic accident owing to driving unskilled making a dash across the red light of causing.
In the specific embodiment of the utility model embodiment, described picture processing chip also is used for extracting from image whether traffic signal lamp flicker occurs or traffic signal lamp continue duration countdown demonstration numeral.This mode can analyze current green light and can also last long, so that auxiliary judgment is made in driving.Certainly, can also judge further in the utility model embodiment whether traffic signal lamp are green light.That is: can obtain traffic signal lamp, and determine whether to be green light by position and/or the color of traffic signal lamp.Because the letter by ordinary signal lamp may comprise craspedodrome lamp, left-hand rotation lamp, right-hand rotation lamp; The synchronous signal lamp also has two kinds of transversely arranged and longitudinal arrangements, thus this picture processing chip need to go out current signal lamp according to various situation analysis be red light, amber light or green light.In the utility model embodiment, whether described data processing chip glimmers according to described traffic signal lamp or traffic signal lamp continue duration countdown demonstration numeral to determine to allow transit time; And arrive the predetermined running time of stop line according to current vehicle speed and stop line location positioning; Determine that according to described permission transit time and predetermined running time can vehicle normally pass through stop line.
