Embodiment 1

[0068] In this embodiment, a case where a vehicle passes through a road with a ramp entrance is taken as an example for description.

[0069] Such as figure 2 As shown, it is a schematic diagram of the road containing the entrance of the ramp. From the ramp 23, it can merge into the main road 22, and there is a speed limit camera 21 in front of the entrance where the ramp merges into the main road. The speed limit camera 21 is used to monitor driving on the ramp. Usually, the speed limit requirement on the ramp is that the driving speed of the vehicle cannot exceed 40 km / h. If the speed of the vehicle traveling on the ramp exceeds the speed limit requirement, the vehicle navigation system will usually prompt the speed limit requirement to remind the driver to slow down. However, if the vehicle is driving on the main road, it should not be restricted by the speed limit requirement on the above-mentioned ramp when passing the ramp entrance. However, in the prior art, if the sp...

Embodiment 2

[0087] When the vehicle is driving on the road, if the car navigation system finds the front speed limit camera, it will prompt relevant information according to the current driving speed of the vehicle.

[0088] The speed limit camera installed on the road monitors the vehicles on a certain lane, that is, monitors whether the speed and type of vehicles on the lane monitored by the speed limit camera meet the relevant requirements of the monitored lane.

[0089] The vehicle navigation system usually prompts corresponding navigation information in advance when the vehicle does not meet the speed limit requirements of the lane monitored by the speed limit camera or the vehicle type allowed by the lane monitored by the speed limit camera, To remind the driver to slow down in time or change to a lane that meets the requirements of the vehicle type.

[0090] However, in the prior art, the car navigation system does not distinguish the current lane of the vehicle. When the vehicle i...

Abstract

A navigation prompting method, a navigation prompting device and a navigation system are provided. The navigation prompting method comprises the following steps: detecting the edge of an image shot by a vehicle-mounted camera through an image edge detection algorithm; determining the current driving lane of a vehicle based on an edge detection result and road information which includes information of the number of lanes of the current driving road of the vehicle; and judging whether the vehicle meets prompting conditions, giving a prompt corresponding to a judging result if the vehicle meets the prompting conditions, or not giving a prompt corresponding to the judging result, wherein the prompting conditions include: the current driving speed of the vehicle exceeds the speed limit required by the current driving lane of the vehicle, and the type of the vehicle is not among the types of vehicles allowed to run on the current driving lane of the vehicle. By adopting the method, the current driving lane of a vehicle can be determined, navigation prompting can be carried out accurately according to the current driving lane of a vehicle, and the accuracy of navigation prompting is improved.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a navigation prompt method and device, and a navigation system. Background technique [0002] With the development of microelectronics technology, computer technology, space technology and mapping technology, vehicle navigation technology has developed rapidly. Vehicles driving on the road can now be navigated through the vehicle navigation system. During the driving process of the vehicle, road condition information, vehicle speed information, etc. are provided to the driver in real time to assist the driver to drive the vehicle conveniently and safely. [0003] In the prior art, a speed-limiting camera is installed on the road on which the vehicle is running to monitor the speed of the vehicle on the lane to ensure driving safety. For example, when a vehicle enters an elevated or expressway, there will be a speed limit requirement. Usually, a speed limit camera is used to m...
