[0026] Best practice model
[0027] According to one aspect of the present invention, a method for generating a virtual image region for motion estimation of a panoramic image is proposed, the panoramic image is divided into tiled tile units and sent from the sending side, the method includes the steps: Search for the reference data corresponding to all or part of the virtual image area of the current collage element in the previous panoramic image, so as to determine the existence of the reference data; and based on the retrieval result, selectively map the reference data to all Or part of the virtual image area.
[0028] The step of mapping the reference data may include the steps of: if the retrieval result indicates that the reference data exists, determining whether the reference data is updated within a predetermined time; and if the determination result indicates that the reference data is updated within a predetermined time, then The reference data is mapped to all or pa...
