US Patent 11003926 Method and apparatus for recognizing boundary of traffic sign

A method and an apparatus for recognizing a boundary of a traffic sign are provided. The method includes: acquiring at least one initial boundary point of a traffic sign in a to-be-processed image, the initial boundary point being used to mark a boundary of the traffic sign; dividing the to-be-processed image into at least one image segmentation area based on the at least one initial boundary point, the image segmentation area including at least one initial boundary point; importing, for an image segmentation area in the at least one image segmentation area, the image segmentation area into a pre-trained traffic sign boundary point recognition model to obtain an update boundary point corresponding to the image segmentation area; and determining a boundary point of the traffic sign based on all the update boundary point corresponding to the image segmentation area.
