preparation example Construction

[0079] The viewpoint synthesis method proposed by the present invention is applied to a viewpoint synthesis system. The viewpoint synthesis system is composed of a compressed resolution network, a viewpoint synthesis network and a super-resolution network. The compressed resolution is connected to the super-resolution network through the viewpoint synthesis network. The output of the compressed resolution is connected to the input of the view synthesis network, and the output of the view synthesis network is connected to the input of the super-resolution network. The compressed resolution network is used to adjust the image resolution of the image before view synthesis; the super-resolution network is used to adjust the image resolution of the image after view synthesis, so that the degradation information of the image in the compressed resolution network can be super-resolution The network is effectively restored; the viewpoint synthesis network is used to synthesize the viewp...

Abstract

The invention discloses a viewpoint synthesis method, device and equipment and a computer readable storage medium, and the method comprises the following steps: obtaining a plurality of input images,and inputting the input images to a compression resolution network, so as to carry out the compression resolution operation of the input images, and obtaining an intermediate image; inputting the intermediate image into a viewpoint synthesis network to obtain a viewpoint synthesis image; and inputting the viewpoint composite graph into a super-resolution network to perform resolution reconstruction operation on the viewpoint composite graph, and outputting a high-resolution target viewpoint composite graph, the compression resolution network being symmetrical with the network structure of thesuper-resolution network. According to the invention, the operand of viewpoint synthesis data is reduced by compressing the resolution network and the super-resolution network, so that the operand ofa computer system is reduced, the operation efficiency of the computer is improved, and the technical problem of low operand of viewpoint synthesis by the computer system is solved.

Description

technical field [0001] The present invention relates to the technical field of view synthesis, in particular to a view synthesis method, device, equipment and computer-readable storage medium. Background technique [0002] The view synthesis of light field can also be regarded as angular super-resolution. Due to the limitation of angular resolution, in order to generate smooth viewpoint transition, the use of viewpoint synthesis technology can generate denser virtual viewpoint from sparse light field viewpoint, so more dense virtual viewpoint can be obtained. Good visual experience. In addition, increasing angular resolution through light field viewpoint synthesis technology is also beneficial to subsequent processing algorithms, such as refocusing, depth estimation, quality enhancement, object detection, etc. Therefore, it is valuable to design an efficient and fast light-field view synthesis method to improve 3D immersive experience and real-time processing performance. ...
