The invention discloses a 4K ultra-high-definition real-time cloud
stream pushing and rendering method and
system, and the method comprises the steps: training an over-fitting super-resolution model for each virtual scene at a cloud end, transmitting the over-fitting super-resolution model to a
client, only needing to transmit a low-quality image, greatly reducing the bandwidth demand and
delay, and achieving the real-time cloud
stream pushing and rendering. And meanwhile, a lightweight super-resolution model is utilized to process a low-quality image at a
client to generate a 4K output image, so that the performance
bottleneck of low-configuration equipment is broken through, and real-time rendering of 4K ultra-high-definition
image quality can be realized in a resource-limited environment. Besides, through mechanisms such as multi-scale gradient loss and dynamic space attention, scene adaptability and detail performance are enhanced, the problem of detail blurring of a
general algorithm is avoided, and therefore the visual effect and
processing efficiency far better than those of a traditional method are provided in a specific virtual scene. And the obvious improvement is brought to the improvement of the user experience in the fields of digital twinning, analogue
simulation, cloud games and the like.
