Problems solved by technology
[0005] Region growing and boundary tracking are based on the segmentation of the region to be segmented as a connected region (that is, all pixels of the target are connected), and its recursive call and full traversal segmentation are slow and cannot meet the real-time requirements; moreover, it cannot be segmented due to The area where the signs are not connected due to incompleteness, in the case of incomplete pavement signs, will cause missing or incomplete segmentation of pavement signs

Embodiment Construction
[0087] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.
[0088] In the embodiment of the present invention, the method and device for segmenting the region of interest of road markings utilizes the fact that road markings in the real world have a fixed size and shape, and sets a search box of a size corresponding to the road marking to be recognized on the top-view image, and searches for it by moving box to complete the segmentation of the pavement marking candidate area. Specifically, acquire a road surface image and generate a binary signature map from the road surface image; respectively generate a top view corresponding to the road surface image and the binary signature map; use a preset search box to search the top view of the binary signature map Determine the ...

The invention relates to the technical field of image partition, and discloses a method and a device for partitioning interest regions of road markings. The method comprises the following steps: acquiring road surface images and generating a two-value labeled graph by the road surface images; respectively generating plans corresponding to the road surface images and the two-value labeled graph; using a preset search box to determine the position of the interest regions of the road markings in the plans of the two-value labeled graph; and portioning the interest regions of the road markings from the plans of the road surface images according to the determined position of the interest regions of the road markings. By using the invention, instantaneity and integrality of the partitioned roadmarkings can be ensured.
Description
technical field [0001] The invention relates to an image segmentation technology, in particular to a method and a device for segmenting a region of interest of a road marking. Background technique [0002] At present, with the development of social economy, the transportation is more and more developed and convenient, and the traffic safety issues are attracting more and more attention. The automatic recognition of road signs by using cameras and other equipment installed on vehicles can effectively remind drivers of current road information, help drivers improve safety awareness, and reduce accident rates. [0003] Different pavement signs have different meanings, such as diamond signs, arrow signs, etc. In the prior art, image segmentation technology is usually used to recognize various road signs. The image segmentation is a technique for segmenting a region of interest that may contain an object to be identified from an image, and its purpose is to provide input for id...
