如下具体实施方式将结合上述附图进一步说明本发明。 The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

具体实施方式 Detailed ways

下面结合附图及较佳实施方式对本发明作进一步详细描述: Below in conjunction with accompanying drawing and preferred embodiment the present invention is described in further detail:

请参阅图1,本发明交通标志提示系统1安装于一车辆500上,用于侦测车辆500前方的道路两侧的交通标志,并根据车辆目前的状态对应提醒驾驶者。 Please refer to FIG. 1 , the traffic sign reminder system 1 of the present invention is installed on a vehicle 500 for detecting traffic signs on both sides of the road in front of the vehicle 500 and correspondingly reminding the driver according to the current state of the vehicle.

请继续参考图2,该交通标志提示系统1的较佳实施方式包括一摄像单元10、一存储模块12、一识别模块15、一读取模块16、一提示模块18及一车辆状态分析模块19。 Please continue to refer to Fig. 2, the preferred embodiment of this traffic sign prompting system 1 comprises a camera unit 10, a storage module 12, a recognition module 15, a reading module 16, a prompt module 18 and a vehicle state analysis module 19 .

该存储模块12内存储有若干交通标志的标准图像及每一交通标志所对应的警示信息。本实施方式中,使用者可预先通过摄像单元10对目前使用的交通标志的标准图像进行拍摄,以得到若干交通标志的图像,并对应输入各交通标志所代表的警示信息。该若干交通标志的图像及其所对应的警示信息均被存储于该存储模块12内。 The storage module 12 stores standard images of several traffic signs and warning information corresponding to each traffic sign. In this embodiment, the user can take a standard image of the currently used traffic signs through the camera unit 10 in advance to obtain images of several traffic signs, and correspondingly input the warning information represented by each traffic sign. The images of the plurality of traffic signs and the corresponding warning information are all stored in the storage module 12 .

该摄像单元10为一摄像头,其可装设于车辆500的头部,以拍摄车辆500前方道路两侧的场景的图像。当然,该摄像单元10亦可设置于其它位置,只要保证其能够采集到车辆500前方的道路两侧的场景即可。另外,该摄像单元10的数量亦可为多个。 The camera unit 10 is a camera, which can be mounted on the head of the vehicle 500 to capture images of scenes on both sides of the road ahead of the vehicle 500 . Of course, the camera unit 10 can also be arranged at other locations, as long as it can capture scenes on both sides of the road in front of the vehicle 500 . In addition, the number of the imaging unit 10 may be plural.

该识别模块15用于识别得到的场景的图像内是否具有交通标志的图像。本实施方式中,该识别模块15将得到的图像与存储于存储模块12内的若干交通标志的标准图像进行比较,以判断场景的图像中是否含有与其中一交通标志的标准图像相同的部分,若场景的图像中含有与某一交通标志的标准图像相同的部分,该识别模块15即认为该场景的图像中包括交通标志。 The identification module 15 is used to identify whether there is an image of a traffic sign in the obtained image of the scene. In this embodiment, the recognition module 15 compares the obtained image with standard images of several traffic signs stored in the storage module 12 to determine whether the image of the scene contains the same part as the standard image of one of the traffic signs, If the image of the scene contains the same part as the standard image of a certain traffic sign, the recognition module 15 considers that the image of the scene includes the traffic sign.

该读取模块16用于在识别模块15判断场景的图像中包括交通标志时从该存储模块12中读取该交通标志所对应的警示信息,并通过提示模块18提示驾驶人员此时道路前方出现何种交通标志。为了使驾驶人员不疏忽该警示信息,该提示模块18可通过声音与图像两个方面来提醒驾驶人员,以使得驾驶人员采取相应的措施。 The reading module 16 is used to read the warning information corresponding to the traffic sign from the storage module 12 when the recognition module 15 determines that the image of the scene includes a traffic sign, and prompts the driver through the prompt module 18 that there is a traffic sign in front of the road at this time. What kind of traffic sign. In order to prevent the driver from neglecting the warning information, the prompt module 18 can remind the driver through sound and image, so that the driver can take corresponding measures.

该车辆状态分析模块19用于在识别模块15判断场景的图像中包括交通标志时,比较此时车辆的状态(如车速等)与该交通标志所对应的警示信息,以判断驾驶人员此时是否违反该交通标志所对应的警示信息,并在驾驶人员违反该交通标志所对应的警示信息时通过提示模块18提醒驾驶人员。比如说,当该识别模块15判断场景的图像中包括交通标志且读取模块16从存储模块12中读取该交通标志对应的警示信息为“最高限速60公里/小时”时,该车辆状态分析模块19即读取车辆此时的行驶速度并将其与60公里/小时进行比较,假设此时车速为80公里/小时,该提示模块18则提醒驾驶人员此时已超速。 The vehicle state analysis module 19 is used to compare the state of the vehicle (such as vehicle speed, etc.) Violate the warning information corresponding to the traffic sign, and remind the driver through the prompt module 18 when the driver violates the warning information corresponding to the traffic sign. For example, when the identification module 15 judges that the image of the scene includes a traffic sign and the reading module 16 reads the warning information corresponding to the traffic sign from the storage module 12 as "maximum speed limit 60 km/h", the vehicle state The analysis module 19 promptly reads the running speed of the vehicle at this moment and compares it with 60 km/h, assuming that the speed of the vehicle is 80 km/h at this moment, the prompt module 18 then reminds the driver to exceed the speed limit.

请参考图3,本发明交通标志提示方法的较佳实施方式包括以下步骤: Please refer to Fig. 3, a preferred embodiment of the traffic sign prompting method of the present invention includes the following steps:

步骤S1:该摄像单元10拍摄车辆500前方道路两侧的场景的图像。 Step S1: The camera unit 10 takes images of scenes on both sides of the road in front of the vehicle 500 .

步骤S2:该识别模块15识别得到的场景的图像内是否具有交通标志的图像。若场景的图像内包括交通标志的图像,则执行步骤S3。若场景的图像中不包括任何交通标志的图像,则返回至步骤S1。 Step S2: The identification module 15 identifies whether there is an image of a traffic sign in the obtained image of the scene. If the image of the scene includes an image of a traffic sign, step S3 is executed. If the image of the scene does not include any traffic sign image, return to step S1.

其中,步骤S2中,该识别模块15将得到的图像与存储于存储模块12内的若干交通标志的标准图像进行比较,以判断场景的图像中是否含有与其中一交通标志的标准图像相同的部分,若场景的图像中含有与某一交通标志的标准图像相同的部分,该识别模块15即认为该场景的图像中包括交通标志。 Wherein, in step S2, the recognition module 15 compares the obtained image with the standard images of several traffic signs stored in the storage module 12, to determine whether the image of the scene contains the same part as the standard image of one of the traffic signs , if the image of the scene contains the same part as the standard image of a traffic sign, the recognition module 15 considers that the image of the scene includes a traffic sign.

步骤S3:该读取模块16读取该交通标志所对应的警示信息。 Step S3: the reading module 16 reads the warning information corresponding to the traffic sign.

步骤S4:该提示模块18提示驾驶人员此时道路前方出现何种交通标志。 Step S4: The prompting module 18 prompts the driver what kind of traffic sign appears ahead of the road at this time.

步骤S5:该车辆状态分析模块19比较此时车辆的状态(如车速等)与该交通标志所对应的警示信息,以判断驾驶人员此时是否违反该交通标志所对应的警示信息。若驾驶人员违反该交通标志所对应的警示信息,则执行步骤S6。若驾驶人员未违反该交通标志所对应的警示信息,则返回步骤S1。 Step S5: The vehicle state analysis module 19 compares the state of the vehicle (such as vehicle speed) with the warning information corresponding to the traffic sign to determine whether the driver violates the warning information corresponding to the traffic sign. If the driver violates the warning information corresponding to the traffic sign, step S6 is executed. If the driver does not violate the warning information corresponding to the traffic sign, return to step S1.

步骤S6:该提示模块18提醒驾驶人员此时已违反交通标志所对应的警示信息。 Step S6: The reminder module 18 reminds the driver that the warning information corresponding to the traffic sign has been violated at this time.

上述交通标志提示系统及方法通过设置于车辆500上的摄像单元10拍摄前方道路两侧的场景的图像,并自动识别场景内是否包括交通标志。当前方的场景包括交通标志时即主动提醒驾驶人员,以避免驾驶人员由于疏忽而没有留意到前方的交通标志。另外,该交通标志提示系统及方法还在侦测到前方的场景内包括交通标志时判断此时驾驶人员是否违规,从而可以更进一步的提醒驾驶人员采取措施,进而避免事故的发生。 The above-mentioned traffic sign prompting system and method use the camera unit 10 installed on the vehicle 500 to capture images of scenes on both sides of the road ahead, and automatically identify whether the scene includes traffic signs. When the scene ahead includes traffic signs, it will actively remind the driver to prevent the driver from not paying attention to the traffic signs ahead due to negligence. In addition, the traffic sign prompting system and method can also judge whether the driver is violating the rules when detecting the traffic sign in the scene ahead, so as to further remind the driver to take measures to avoid accidents.
