Method, apparatus, and system for automatically annotating a target object in images

Abstract:

Embodiments of the disclosure disclose a method for automatically annotating a target object in images. In one embodiment, the method comprises: obtaining an image training sample including a plurality of images, wherein each image of the plurality of images is obtained by photographing a same target object, and the adjacent images share one or more same environmental feature points; using one of the plurality of images as a reference image to determine a reference coordinate system, and create a three-dimensional space model based on the three-dimensional reference coordinate system; determining the position information of the target object in the three-dimensional reference coordinate system upon the three-dimensional space model being moved to the position of the target object in the reference image; and mapping the three-dimensional space model to image planes of each image, respectively, based on respective camera pose information determined based on environmental feature points in each image.
