Abstract

The invention provides a light field super-resolution imaging method, device and equipment. The method comprises the following steps: inputting a to-be-processed image into a trained target network model to obtain a super-resolution image, the target network model being obtained by training in the following modes: inputting an original image sequence into an initial network model to obtain a target image sequence; obtaining a content loss value of a target image in the target image sequence and a sample image in the sample image sequence, and a structure loss value of the target image in the target image sequence and the sample image in the sample image sequence; determining whether the initial network model is converged or not according to the content loss value and the structure loss value; if so, determining the initial network model as a trained target network model; and if not, adjusting the initial network model, determining the adjusted network model as the initial network model, and returning to execute the operation of inputting the original image sequence into the initial network model to obtain a target image sequence. Through the technical scheme of the invention, the resolution of the image is effectively improved.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a light field super-resolution imaging method, device and equipment. Background technique [0002] The resolution of an image refers to the amount of information stored in the image, which is the number of pixels per inch of the image. The unit of resolution is PPI (Pixels Per Inch, pixels per inch). Obviously, the larger the resolution, the higher the resolution of the image. The higher the sharpness and the lower the resolution, the lower the sharpness of the image. In practical applications, the resolution of the image, the width of the image and the height of the image together determine the size and quality of the image. [0003] With the development of super-resolution imaging technology, more and more application scenarios, such as automatic driving, medical imaging, satellite imaging, film and television, AR (Augmented Reality, augmented reality) / VR (Virtual Rea...
