摘要
提出了利用“辐射状分辨率图案”测量电视跟踪系统摄像头分辨率的新方法,它取了“分辨率板法”的优点,避免了目视分辨率板法的缺点。介绍了一种基于图像时空域特征的数字化测试系统。该系统利用图像采集卡实时采集电视跟踪系统摄像头输出的视频图像信号,通过数据和图像处理后计算出摄像头的分辨率。测试过程实现了自动化,试验重复性好,测试结果客观可靠,能够更加合理、准确地反映电视跟踪系统摄像头的成像质量。
A new method to measure camera resolution of TV tracking system by using radiate pattern resolution target is introduced. It takes advantage of the resolution test target, while avoiding the disadvantage of visual method. A digital measurement system based on the spatial-temporal field features of image is introduced. The system uses the image acquisition card to acquire the video signal from the camera in real-time, through the data and image processing to measure the camera resolution. The measurement is performed automatically with excellent repeatability. The measurement result is objective and reliable so that the imaging quality of the camera to be reflected is more reasonable and accurate.
