Problems solved by technology

[0004]Secondly, the general navigation system cannot know the road conditions of the lane the driver is currently driving or whether the lane is open for traffic, and the driver usually has to be alert to pay attention to the lane road ahead
If a driver accidentally drives into a non-travelable lane (such as a bus lane, an oncoming lane that is open during rush hour) without paying attention, it will result in a penalty
What's more, if there is an accident in front of the current driving lane or the road is under construction, it will also endanger the safety of drivers.

[0043] figure 1 is a flow chart of the vehicle navigation method according to the first embodiment of the present invention. Please refer to figure 1 , this embodiment is applied to an electronic device with a vehicle navigation system, and combines lane detection technology with the vehicle navigation system to assist navigation.

[0044] First, in step S105, the current driving lane of the vehicle is detected by using road detection technology. For example, image-based lane detection technology can know the current driving lane, lane markings, the relationship between vehicles and lanes, etc. through the calculation of image data. For example, an image capture unit such as a camera can be used to capture a driving picture while driving, so as to detect the current driving lane by using the road detection technology based on image recognition based on the driving picture. In addition, in other embodiments, the road detection technology may also be detected by a sensor. ...

[0058] image 3 is a flow chart of the vehicle navigation method according to the second embodiment of the present invention. Please refer to image 3 , in this embodiment, the road detection technology based on image recognition combined with GPS positioning service is taken as an example for illustration.

[0059] In step S305, a camera function is activated to capture a picture of driving, so as to obtain a real-time video picture. Next, in step S310, the current driving lane of the vehicle is detected by using the driving image. Afterwards, in step S315, it is judged whether the current driving lane matches the navigation lane that should be driven in the navigation information. Here, step S310 and step S315 are similar to step S105 and step S110 in the first embodiment, so they are not repeated here.

[0060] When the vehicle navigation system is activated, as shown in step S320, the vehicle navigation system will activate the GPS for navigation, so as to obtain navig...

[0065] The present embodiment provides a vehicle navigation system capable of executing the above vehicle navigation method. Figure 4 is a block diagram of a vehicle navigation system according to a third embodiment of the present invention. This embodiment is described by using the road detection technology based on the image recognition technology. However, in other embodiments, the road detection can also be performed by sensors, which does not limit the road detection technology.

[0066] Please refer to Figure 4 , Here, the vehicle navigation system 400 is, for example, configured in an electronic device, such as a mobile phone, a personal digital assistant (Personal Digital Assistant, PDA), a PDA mobile phone, a car computer (Car PC), a navigation device, a notebook Computers, music players, digital cameras, camcorders, game consoles and other handheld electronic devices or automotive electronic devices. The vehicle navigation system 400 includes a lane detection mo...

Abstract

The invention relates to a vehicle navigation method and system. The method comprises the following steps: the road detection technology is utilized to detect the current driving lane of a vehicle; then whether the current driving lane corresponds with a navigation lane in the navigation information is judged; and if not, the direction of the navigation lane relatively to the current driving lane is prompted. Therefore, the lane to be switched for driving can be informed to the driver.

Description

technical field [0001] The invention relates to a navigation technology, in particular to a vehicle navigation method, system and computer program product combined with lane detection technology. Background technique [0002] With the advancement of science and technology, means of transportation has become one of the important inventions in modern development. However, due to the rapid development of cities, road connections are becoming more and more complicated. Therefore, the emergence of navigation systems, such as Global Position System (Global Position System, GPS) navigation system, traffic message channel (Traffic Message Channel, TMC), brings great convenience to human beings. The current common car navigation devices can not only provide guidance services such as roads and scenic spots, so that drivers can understand the current driving conditions, but also locate and track the driver's position, direction, speed, etc. [0003] Generally speaking, drivers often...
