Example Embodiment

[0042] The process in the second embodiment can also be used to identify the number of lanes. The B channel can be selected in the color space. The outline area identification process in step 24 is as follows:

[0043] Determine whether condition (a) or condition (b) is met,

[0044] (a) Contour area ≥ minimum circumscribed rectangle area * 0.55; minimum circumscribed rectangle area ≥ 150; minimum circumscribed rectangle width> minimum circumscribed rectangle height * 3 or minimum circumscribed rectangle width * 3 Minimum Enclosing Rectangle Height ;0.1 radians≤minimum circumscribed rectangle angle≤1.1111 radians;

[0045] (b) Contour area ≤ 5600; the center coordinate of the smallest circumscribed rectangle y> the center coordinate of the smallest circumscribed rectangle x / 2+166-95; the center coordinate of the smallest circumscribed rectangle y>666-the center coordinate of the smallest circumscribed rectangle x / 2-12016; The coordinate of the center of the rectangle y<655; the c...

Abstract

The invention discloses a method for automatically identifying structures in front of roads, which has the steps of: extracting a single channel from the color space of an image; carrying out binaryzation treatment to the extracted single channel; connecting connected domains in the treated image; confirming corresponding structures, if geometric areas of images in the connected domains meet a preset range value; selecting an image treatment area according to the coordinates of the structures before or after the binaryzation treatment, or adopting a preset moulding board to carry out wave filtering to the image, so as to filter the typical lines of the image; and adopting lines to mark the structures in the image. The method can effectively identify the structures in the image, has simple process, can carry out wave filtering to the image with different structures so as to filter the typical lines of the image, thus providing convenience for the subsequent image contour identification; and an identified sight is marked by the lines, so as to be convenient for analysis processing during road detection.

Description

Technical field [0001] The invention relates to the technical field of image processing, in particular to a method for automatically identifying structures in front of a highway. Background technique [0002] In the process of road detection, the detected images are used to analyze the road conditions in the future. In the later process of analyzing the road through image detection, it is necessary to identify the structure of the road to facilitate subsequent Analysis and processing, at present, there is no technology that can identify the structure in the image. Summary of the invention [0003] In view of this, the present invention is to provide a method for automatically identifying structures in front of a highway to solve the above-mentioned problem that the existing image processing technology cannot identify structures in the image. [0004] In order to solve the above problems, the present invention provides a method for automatically identifying structures in front of...
