Embodiment Construction

[0050] 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 in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0051] Such as figure 1 Shown, method step of the present invention is as follows:

[0052] S1: Use the camera module to collect real-time image information of the road surface, the real-time image information is a YUV spatial image, as follows:

[0053] Obtain the data of the YUV space image directly through the camera module, convert it from the YUV space to the RGB space image, and set it as img_src.

[0054] S2: Use the mobile platform to process the real-time image information obtained by the camera module, and convert the YUV space image into an RGB space image, as follows:

[0055] Conver...

Abstract

The invention discloses a method and a device for road edge recognition based on a mobile platform. The method comprises the following steps: using a camera module to acquire real-time pictorial information of a road; using the mobile platform to process the real-time pictorial information acquired by the camera module; converting a YUV spatial image into an RGB spatial image; converting the acquired RGB spatial image into an HSV spatial image; performing binaryzation process for the HSV spatial image; converting the acquired RGB spatial image into a grayscale image and performing edge and line detection; performing further screening for the detected lines according to the acquired zone in which the road edge is located; selecting the longest line in the road edge zone as a road edge. The method and the device solve the problems that the algorithm of the conventional road edge recognition system takes up a huge memory, is poor in real-time property, and is susceptible to interference from the outer environment, and most algorithms are only suitable for detecting ideal roads with clear edges.

Description

technical field [0001] The invention relates to a method and device for road edge recognition, in particular to a method and device for road edge recognition based on a mobile platform. Background technique [0002] Currently, image color modes commonly used in electronic devices are as follows. [0003] RGB color space: A variety of colors are obtained by changing the three color channels of red (R), green (G), and blue (B) and superimposing them with each other. RGB stands for red and green The color of the three channels of blue and blue, this standard includes almost all the colors that can be perceived by human eyesight, and is one of the most widely used color systems at present. The main purpose of the RGB color model is to detect, represent and display images in electronic systems, such as televisions and computers, but it also has applications in traditional photography. [0004] YUV color space: YUV, like RGB, is used to represent colors, and the two can be conve...
