Data display method and device, storage medium and electronic equipment

Abstract

The embodiment of the invention provides a data display method and device, a storage medium and electronic equipment, and relates to the technical field of smart cities. The method comprises the steps: determining the sizes and positions of a first window and a second window in a data display interface according to historical operation data, so the user operation efficiency is improved; displayinga first image under a large viewing angle and a navigation image representing the position of the first image in the second image on the first window, and displaying a second image under a small viewing angle on the second window; acquiring a control operation of a user on a first window of the data display interface; converting the control operation into an angle in a three-dimensional space; obtaining an updated second projection matrix according to the angle; updating and displaying the second image under the small view angle according to the updated second projection matrix, thereby improving the understanding efficiency of the image data content; and updating and displaying the navigation image according to the second projection matrix, thereby improving the speed of positioning theregion of interest in the image data by the user.

Description

technical field [0001] The present application relates to the technical field of smart cities, and in particular to a data display method, device, storage medium, and electronic device. 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. The traditional flat camera can only monitor a scene in one direction, but the fisheye camera can monitor a wider field of view due to its wider viewing angle. In this way, the site that originally needed multiple flat cameras to monitor, now only needs one fisheye camera. It can be solved, which greatly saves the hardware cost. [0003] Because the fisheye camera has a wider angle of view, the captured fisheye image (image data) often has great distortion, and the captured fisheye image is usually displayed in a circle, which is not easy to un...

Problems solved by technology

[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 professional skills Only people can understand it, so the application of fisheye images cannot be well promoted
