Data display method, mobile terminal and storage medium

Abstract

The embodiment of the invention provides a data display method, a mobile terminal and a storage medium, and relates to the technical field of intelligent cities. The method comprises the steps that aCPU copies image data to obtain first image data and second image data; the first GPU renders the first image data into a first image under a large viewing angle and displays the first image; the second GPU generates a second image under a small viewing angle according to the second image data and displays the second image; the third GPU performs processing to obtain a navigation image according to the determined three-dimensional navigation area in the first image model corresponding to the second image so as to highlight the navigation image in the first window; the CPU acquires a control operation of the user on the first window based on the navigation image, converts the control operation into an angle in a three-dimensional space, and updates a second projection matrix corresponding to the second window according to the angle; and the second GPU and the third GPU update the second image and the navigation image according to the second projection matrix. The embodiment of the invention improves the understanding efficiency of the image data and reduces the power consumption of the mobile terminal.

Description

technical field [0001] This application relates to the technical field of smart cities, and in particular to a data display method, a mobile terminal and a storage medium. 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 r...
