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

Abstract

The embodiment of the invention provides a data display method for a fish eye camera and a mobile terminal, and relates to the technical field of smart cities. The method comprises the steps that a CPU copies image data to obtain first image data and second image data, and the first image data and the second image data are transmitted to a first processing unit and a second processing unit respectively; the first processing unit renders the first image data into a first image under a large viewing angle according to the first projection matrix and a first image model, 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 projection matrix, a second image model and the second image data, and displays the second image in a second window; and a third processing unit determines and processes a target navigation area in the first image model corresponding to the second image according to the second projection matrix and the first image model so as to obtain a target navigation image and highlight the target navigation image. 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 and a mobile terminal for a fisheye camera. 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 an...
