Embodiment Construction

[0019] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0020] A method for displaying an image using OpenCV, comprising the steps of:

[0021] 101. The function myShowWindow for displaying images in the application software of windows is created in the environment of VC (developing Windows environment program based on C++ language, object-oriented visual integrated programming system released by Microsoft Corporation), and the function includes the following parameters: iOffsetX , iOffsetY, iWidth, iHeight, imageSize, SImageData; among them, iOffsetX and iOffsetY indicate the relative position of the image displayed in the application software window, which can be specified as required, iWidth and iHeight respectively indicate the width and height of the image, and imageSize indicates the image to be displayed The size of the data buffer occupied by the pixel, the value of imageSi...

Abstract

The invention discloses a method of using an OpenCV (Open Source Computer Vision Library) to display an image. The method comprises the following steps: S1, calling an OpenCV library function in application software, and opening or generating the to-be-displayed image; S2, acquiring values of nChannels, width, height, widthStep and imageData in a structure body IplImage; S3, converting the values of the imageData to SImageData, wherein the SImageData is used to store values of pixel points of the to-be-displayed image in a format used by the application software; and S4, displaying the to-be-displayed image in a window of the application software. According to the method of using the OpenCV to display the image provided by the invention, the image processed by calling the OpenCV can be enabled to be directly displayed in the application software window without the need for popping up a new window, and a user experience degree is increased.

Description

technical field [0001] The invention relates to the field of image pattern recognition software development, in particular to a method for displaying images using OpenCV. Background technique [0002] OpenCV, or "Open Source Computer Vision Library" (Open Source Computer Vision Library) is a set of cross-platform, open-source middle and high-level "application programming interface" APIs composed of more than 500 C functions organized by Intel (Intel Corporation) in 1999. (Application Programming Interface, application programming interface) development library. Because it is open source based on BSD (Berkeley Software Distribution, Berkeley software suite) license, anyone can download the source program and runtime library of the library from its website, and after calling their own program, there is no need to publish the source code. And it can be used in commercial software and is very popular. Currently, the development library can run on Linux, Windows and Mac OS ope...
