More Information
Summary:The invention provides a repositioning method, a repositioning device, a storage medium and electronic equipment, and relates to the technical field of computer vision. The method comprises the stepsthat guiding information is generated based on semantic tags of key frame images in map data, and the guiding information is used for guiding collection of images related to a real scene in repositioning; extracting semantic features of the acquired current frame image to obtain a semantic label of the current frame image; comparing whether the semantic tag of the current frame image is similar tothe semantic tag of each key frame image, If so, determining the key frame image as a similar key frame image; and matching the current frame image with the similar key frame image to obtain a current pose. According to the invention, the scene image can be guided and collected through the guide information, the repositioning process is accelerated, the key frame image is screened in a semantic tag comparison mode, the op
