Abstract: The present application provides a panoramic video picture quality display method and device. Attention position information of a user at different time points in a preset period of time is obtained, the attention position information includes a picture horizontal angle; an attention information curve is created in a polar coordinate system, the attention information curve takes the time point as a polar radius and the picture horizontal angle obtained at the time point as a polar angle; and a picture quality parameter can also be obtained and the picture quality parameter is marked on the attention information curve to display the picture quality parameter.

Abstract: The present application provides a method and device for picture quality assessment after dynamic panoramic video stream cropping. An attention focus parameter is obtained, the attention focus parameter is used for representing an attention level of a user to a picture and the attention focus parameter is a function of a picture angle and a picture height; a resolution distribution parameter is obtained; the attention focus parameter and the resolution distribution parameter are combined to obtain a picture quality parameter that the user views in a dynamically cropped panoramic video stream; and the picture quality is assessed according to the picture quality parameter.
