Embodiment Construction

[0063] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0064] figure 1 It is a schematic diagram of the composition and structure of the device for realizing car navigation in the present invention, as figure 1 As shown, it includes an image capture unit, a landmark pre-detection unit, a landmark segmentation unit, a landmark recognition unit and a landmark output unit, wherein,

[0065] The image capture unit is used to take pictures according to the preset shooting parameters on the driving road of the car, and transmit the captured image information to the road sign pre-detection unit. Here, the shooting parameters may be but not limited to: the focal length of the lens, the frequency of taking pictures, and the control information of the shutter. The image capture unit can be realized by using a camer...

Abstract

The invention discloses a method, a device and a camera for achieving car navigation. The scheme of the invention is that the method comprises the following steps: adopting a common camera to shoot according to preset shooting parameters so as to acquire image information, and performing initial survey on the acquired image information to acquire the image information probably containing road sign information; performing correction processing on the acquired image information probably containing the road sign information, then performing road sign detection, and dividing out road sign images when road signs exist in the image information; and dividing out a word and icon area from the acquired road sign image information, and displaying words and icons after recognizing the words and the icons in the word and icon area. Through the scheme, a driver can accurately acquire the road sign information from a display screen for the convenience of examining routes or performing accurate judgments on driving by the driver. The method, the device and the camera simply and cheaply achieve the car navigation.

Description

technical field [0001] The invention relates to camera processing technology, in particular to a method, device and camera for realizing car navigation. Background technique [0002] At present, the simplest car navigation method is to use an ordinary camera to assist the driver in positioning, and display the pictures collected by the camera for the driver's positioning as a reference. Because the original picture captured by the camera will have a large distortion, in fact, this method not only cannot play a navigation role, but may also cause wrong judgments by the driver; moreover, this method is not intelligent. It can be seen that although this method is simple and the cost is very low, it is hardly practical. [0003] Therefore, most drivers who want to use a car navigation system usually choose GPS or the domestic Beidou navigation system to realize car navigation. Both of these navigation products rely on satellites for positioning, which is expensive, so it is di...
