基于图像采集卡的图像显示与处理软件开发
Development of Image Displaying and Processing Software Based on Image Grabbing Card
摘要
利用图像采集卡与计算机构成图像处理系统开发了一款软件, 用于采集显示CCD相机整机系统输出的图像并计算输出图像调制度, 为相机系统的综合像质评价提供依据。充分利用Matrox公司为其图像采集卡提供的二次开发函数库MIL库, 在VC++6.0开发环境中调用MIL库函数实现了相机系统输出图像的显示、存储和调制度计算等功能, 并对主要程序算法进行优化, 提高了软件的性能。实验室测试表明, 该软件能实时显示输出图像并进行相应的处理, 调制度计算结果准确, 软件运行稳定。利用图像采集卡自带的函数库开发图像显示和处理软件, 缩短了开发周期, 提高了软件运行可靠性。
Abstract
For the image processing system consisting of the image grabbing card and computer, a software is developed to grab and display images of the CCD camera system. In the software, the modulations are calculated, which are the indicators for evaluating the general image quality of the CCD camera system. This design takes full advantage of Matrox imaging library for secondary development. The software can display, save and calculate the modulations of output images by invoking functions of Matrox imaging library with VC++ 6.0. To improve the software performance, the main algorithm is optimized. Lab tests show that the software can display and process the output images in real-time. The calculated modulations are accurate and the software operates stably. Using the function library of the image grabbing card to develop image displaying and processing software, development cycle can be shorten and the reliability of the software can be improved.
