Description
technical field [0001] The invention relates to the field of computer vision, in particular to a method, device, electronic equipment and storage medium for determining target optical flow information. Background technique [0002] In the field of computer vision, the optical flow field can be used to describe the position change relationship of each pixel between two frames of images, that is, to describe the spatial motion information of objects. In the existing schemes for determining and compensating optical flow information, it is necessary to estimate the moving object when the camera is shooting in motion. The optical flow field is compensated. [0003] The current compensation scheme for the optical flow field is based on the rotation compensation method proposed by Bideau. In this method, assuming that the rotation parameters of the camera are known, the corresponding optical flow information can be calculated according to the camera rotation parameters, and then b...
