The invention provides a map road element identification method and device, equipment and a storage medium, and belongs to the field of surveying and mapping. The method comprises the following steps: segmenting an original point cloud to obtain at least two local point clouds; road element extraction is carried out based on the local point clouds, and local extraction results corresponding to the local point clouds are obtained; splicing the local extraction results to obtain a global extraction result; and projecting an image semantic segmentation result into a global extraction result to obtain an output point cloud. Local element extraction is carried out by segmenting point clouds, then local extraction results are spliced, based on a mode of re-fusing point cloud recognition results and image recognition results, the image recognition results are utilized to make up for information missing in the point cloud recognition results and solve the problem of discontinuous splicing caused by segmentation, and
