Data labeling method and device, electronic equipment and storage medium

The invention provides a data annotation method and device, electronic equipment and a storage medium, and relates to the technical field of image processing, and the method comprises the steps: determining internal parameter information and external parameter information when image collection equipment collects a plurality of two-dimensional images according to the plurality of two-dimensional images of a three-dimensional scene under multiple visual angles; the three-dimensional scene comprises a target object; and reconstructing the three-dimensional scene based on the internal parameter information and the external parameter information, obtaining an image of the target object in the reconstructed three-dimensional scene based on the implicit expression model, and performing data annotation on the target object in the three-dimensional scene. In the embodiment of the invention, the image of the target object in the reconstructed three-dimensional scene is obtained based on the implicit expression model, a
