Image display method and device and electronic equipment

Abstract

The embodiment of the invention provides an image display method and device and electronic equipment, and relates to the technical field of smart cities. The method comprises the following steps: processing image data acquired by a fisheye camera into a first image under a large viewing angle according to a first projection matrix and an image model, and displaying the first image; when a first switching operation based on the first image is detected, obtaining first position information, second position information and first preset time, determining a first transition projection matrix corresponding to the movement of a virtual camera from the first position information to the second position information within the first preset time, determining a first transition image, and displaying the first transition image; and when the virtual camera moves to the second position information, generating a second image under a small viewing angle according to the second projection matrix and displaying the second image. According to the embodiment of the invention, the understanding efficiency of image data content can be improved, smooth switching between different images displayed at different visual angles is realized, and the user experience is improved.

Description

technical field [0001] This application relates to the technical field of smart cities, in particular to an image display method, device and electronic equipment. Background technique [0002] In traditional video surveillance, it is mainly the display of 2D plane pictures, but with the rise of computer technology, the advantages of fisheye images in the surveillance industry are becoming more and more obvious. Traditional planar cameras can only monitor scenes in one direction, but fisheye cameras can monitor a wider field of view due to their wider viewing angles. In this way, sites that originally required multiple planar cameras to monitor now only need one fisheye camera. It can be solved, and the hardware cost is greatly saved. [0003] Because the fisheye camera has a wider viewing angle, the captured fisheye image (image data) often has a large distortion, and the captured fisheye image is usually displayed in a circle, which is not easy to understand and requires p...
