| description | An image annotation method and apparatus, and a computer readable storage medium. The method comprises: obtaining a fisheye image collected by a fisheye camera (101); processing the fisheye image by means of a rotation matrix parameter to obtain a target image (102); adding, in the target image, an annotation result for a target object (103); and according to the rotation matrix parameter, mapping the annotation result in the target image to the fisheye image (104). According to the present application, converting, by means of the rotation matrix parameter, the fisheye image having a picture distortion into the target image having no distortion or a small distortion, and performing annotation of the target object on the target image can reduce, in an annotation process, an influence caused by a picture distortion; and finally, mapping the annotation result in the target image to the fisheye image by means of the rotation matrix parameter enables the target object in the fisheye image to also have a high-quali |
