Embodiments of the present disclosure disclose methods and devices for identifying boundaries of traffic sign boards. A specific implementation of the method includes: obtaining at least one initial boundary point of the traffic sign in the image to be processed, wherein the initial boundary point is used to mark the boundary of the traffic sign; The image is divided into at least one image segmentation region, wherein the above-mentioned image segmentation region contains at least one initial boundary point; for the image segmentation region in the above-mentioned at least one image segmentation region, the image segmentation region is imported into a pre-trained traffic sign boundary point recognition model , to obtain the updated boundary points of the corresponding image segmentation regions; and determine the boundary points of the above-mentioned traffic signs according to all the above-mentioned updated boundary points of the corresponding image segmentation regions. This embodiment improves the accuracy of identifying the boundaries of traffic sign boards.
Description
technical field [0001] Embodiments of the present disclosure relate to the technical field of image processing, and in particular to a method and device for identifying boundaries of traffic sign boards. Background technique [0002] With the rapid development of smart cars and unmanned driving technology, the recognition of traffic sign detection has become an important part of safe driving. Smart cars can acquire images containing traffic signs, recognize traffic signs from the images, and then realize unmanned driving of smart cars based on traffic signs. But prior art is not accurate enough to the recognition of traffic signboard. Contents of the invention [0003] Embodiments of the present disclosure provide methods and devices for identifying boundaries of traffic sign boards. [0004] In a first aspect, an embodiment of the present disclosure provides a method for identifying the boundary of a traffic sign, the method comprising: obtaining at least one initial bo...
