Traffic sign information processing method and related device

The invention relates to the technical field of computers, and provides a traffic sign information processing method and a related device, which can be applied to various scenes such as cloud technology, artificial intelligence, intelligent traffic, auxiliary driving and maps, and the method comprises the following steps: obtaining a target three-dimensional shape corresponding to a sign to be assigned, and obtaining a target two-dimensional shape and a corresponding target attribute, the target two-dimensional shape and the corresponding target attribute are obtained based on image data collected for multiple times for the to-be-assigned label; and based on respective target positions of the target two-dimensional shape and the target three-dimensional shape under the target coordinate system, obtaining an association relationship between the target three-dimensional shape and the target two-dimensional shape, and further performing attribute assignment of the traffic sign based on the association relationsh
