本发明涉及交通安全领域，具体而言，涉及一种限速提示信息生成方法与装置。The invention relates to the field of traffic safety, in particular to a method and device for generating speed limit prompt information.
背景技术Background technique
智能限速提醒系统用于限速提示信息识别，辅助驾驶员规范行驶，限速提示信息指具有圆形边界的道路速度限速标识，以及电子眼限速。当摄像头或导航探测到限速提示信息后，经过数据融合，在仪表及HUD中显示当前限速值，若驾驶员发生超速行为，智能限速提醒系统将进行声音及视觉警告。The intelligent speed limit reminder system is used to identify the speed limit prompt information and assist the driver to regulate driving. The speed limit prompt information refers to the road speed limit sign with a circular boundary, and the electronic eye speed limit. When the camera or navigation detects the speed limit prompt information, after data fusion, the current speed limit value will be displayed on the instrument and HUD. If the driver has overspeed behavior, the intelligent speed limit reminder system will issue audible and visual warnings.
摄像头用于识别道路限速标识。当摄像头探测到限速标识后，在经过限速标识所在平面起，开始在仪表上进行显示，限速标识显示的有效保持距离依据限速值及当前所在道路类型判定，例如，在高速道路上识别到60km/h的限速标识，该限速值在仪表上的有效保持距离为车辆驶过限速标识平面后1000m的距离，识别到80km/h的限速标识，则保持距离为2200m,又如在城市道路上识别到60km/h的限速标识时，有效保持距离则为700m。保持距离的设定依据大量测试数据所得，在此范围内具有最佳驾驶体验。Cameras are used to recognize speed limit signs on roads. When the camera detects the speed limit sign, it will start to display on the instrument after passing the plane where the speed limit sign is located. The effective keeping distance displayed by the speed limit sign is determined according to the speed limit value and the current road type. For example, on a high-speed road If the speed limit sign of 60km/h is recognized, the effective keeping distance of the speed limit value on the instrument is 1000m after the vehicle passes the speed limit sign plane; if the speed limit sign of 80km/h is recognized, the keeping distance is 2200m. Another example is that when a speed limit sign of 60km/h is recognized on an urban road, the effective keeping distance is 700m. The setting of the maintenance distance is based on a large number of test data, and the best driving experience is within this range.
导航用于识别电子眼限速。当导航探测到电子眼限速后，若当前道路类型为高速道路/城市快速，在电子眼前方700m处即开始显示限速值，且保持距离延长至电子眼身后100m。若当前道路类型为城市道路，在电子眼前方300m处开始显示限速值，且保持距离延长至电子眼身后100m。Navigation is used to recognize the electronic eye speed limit. When the navigation detects the speed limit of the electronic eye, if the current road type is expressway/urban express, the speed limit value will be displayed 700m in front of the electronic eye, and the distance will be extended to 100m behind the electronic eye. If the current road type is an urban road, the speed limit value will be displayed 300m in front of the electronic eye, and the keeping distance will be extended to 100m behind the electronic eye.
在现有技术中，摄像头与导航在限速提示信息上的数据融合采用“最新出现，最新显示”的逻辑方案，然而当车辆行驶于偏远地区时，由于导航定位不准确，未能提供当前道路电子眼限速提示信息，导致漏报，致使驾驶员存在超速违规风险；再者，车辆行驶于偏远地区时，摄像头已识别到交通限速标识，在其保持距离范围内，由于导航定位不准确，提供了错误电子眼限速提示信息，导致仪表限速值发生更新，给出错误限速提示，也会致使驾驶员存在违规风险；或者车辆行驶于偏远地区时，由于导航未能及时更新当前道路电子眼限速提示信息，导致对新增电子眼限速的漏报或已取消电子眼限速的误报，也会致使驾驶员存在违规风险。In the existing technology, the data fusion of the camera and the navigation on the speed limit prompt information adopts the logic scheme of "the latest appearance, the latest display". However, when the vehicle is driving in a remote area, due to the inaccurate navigation positioning, it cannot provide The speed limit prompt information of the electronic eye leads to missed reports, causing the driver to have the risk of speeding violations; moreover, when the vehicle is driving in a remote area, the camera has recognized the traffic speed limit sign, and within the range of its maintenance distance, due to inaccurate navigation and positioning, The wrong speed limit prompt information of the electronic eye is provided, which leads to the update of the speed limit value of the instrument, and the wrong speed limit prompt is given, which will also cause the driver to have a risk of violation; or when the vehicle is driving in a remote area, the current road electronic eye cannot be updated in time due to the navigation. The speed limit prompt information, resulting in missed reporting of the newly added electronic eye speed limit or false alarm of the canceled electronic eye speed limit, will also cause the driver to have a risk of violation.

The speed limit prompt information generating system includes an intelligent speed limit controller 102, an image acquisition module 101, a positioning device 104, and a display screen 103. The intelligent speed limit controller 102 is electrically connected to the image acquisition module 101, the positioning device 104, and the display screen 103 respectively. In this embodiment, the image acquisition module 101 can be a vehicle-mounted camera, and the positioning device 104 can adopt a vehicle-mounted positioning navigator, and the method for generating speed limit prompt information includes:
步骤S201：接收图像采集模块101发送的路牌限速标识以及定位装置104发送的导航地图信息。Step S201 : receiving the road sign and speed limit sign sent by the image acquisition module 101 and the navigation map information sent by the positioning device 104 .

综上所述，本发明提供的限速提示信息生成方法与装置，在当车辆当前的地理位置信息处于偏远地区，车辆行驶的当前道路路况信息为高速道路时；若在先接收到路牌限速标识，在后接收到电子眼限速标识；或同时接收到路牌限速标识、电子眼限速标识时，仅生成与路牌限速标识关联的第一限速提示信息，在偏远地区不会因为导航不准确，导致误报限速标识，从而提高了限速标识识别的可靠性、准确率。In summary, the method and device for generating speed limit prompt information provided by the present invention, when the current geographical location information of the vehicle is in a remote area, and the current road condition information of the vehicle is a high-speed road; After receiving the electronic eye speed limit sign; or when receiving the street sign speed limit sign and the electronic eye speed limit sign at the same time, only the first speed limit prompt information associated with the street sign speed limit sign will be generated. Accurate, resulting in false reporting of speed limit signs, thereby improving the reliability and accuracy of speed limit sign recognition.
