A zero-delay panoramic video bitrate control method considering time domain distortion propagation

The present invention belongs to the field of image processing technology, and specifically relates to a zero-delay panoramic video rate control method considering the propagation of time domain distortion. The method of the present invention is mainly to optimize the target bit allocation and global rate distortion optimization coding, including rate control at the coding tree unit (CTU) level and time domain global rate distortion optimization. CTU-level rate control mainly includes optimizing target bit allocation and updating rate control parameters; time domain global rate distortion optimization mainly uses the reconstruction error and motion compensation prediction error information of the encoded frame to estimate the time domain dependency of each CTU in the current encoded frame and adjust the rate distortion optimization parameters of the CTU accordingly, and at the same time, according to the process of projecting the panoramic spherical graphic onto the 2D plane (ERP projection), the characteristics of oversampling and increasing pixel redundancy will be generated at the two poles, and the coding parameters are adjusted according to the projection area change ratio. The present invention can effectively shorten the encoding time and improve the video encoding quality under the condition of a given bandwidth.
