Data display method and mobile terminal

Abstract

The embodiment of the invention provides a data display method and a mobile terminal, and relates to the technical field of smart cities. The method comprises the steps that a CPU determines the sizesand positions of a first window and a second window in a data display interface according to historical operation data; the CPU copies the image data to obtain first image data and second image data,and transmits the first image data and the second image data to the first processing unit and the second processing unit respectively; the first processing unit renders the first image data into a first image under a large viewing angle and displays the first image in a first window; the second processing unit generates a second image under a small viewing angle according to the second projectionmatrix and the second image data, and displays the second image in a second window; and the third processing unit determines and processes a target navigation area of the second image in a first image model corresponding to the first image according to the second projection matrix so as to obtain a target navigation image and highlight the target navigation image. The embodiment of the inventionimproves the user operation efficiency, 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, in particular to a data display method and a mobile terminal. 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 professional s...
