| 摘 要： | 根据虚拟演播室的需要,利用图像识别技术和Tsai两步校准算法的思想,在VisualC++平台上编制了CCD摄像机的校准软件。首先利用仿真数据对校准算法进行检验和分析,指出其中的规律和问题。其次在真实的蓝色演播室环境中对摄像机进行校准,提出了特定的处理方法,得到了满意的非线性焦距变化曲线。最后,详细分析了图像处理精度和校准算法对校准结果的影响。

| Abstract: | CCD camera calibration software is accomplished based on image recognition and Tsai's two-stage calibration algorithm for the project of virtual studio.First,synthetic data is used to test the calibration algorithm,and some laws and problem of which is presented.Second,camera calibration experiments are made with the calibration algorithm and special techniques in blue studio environment ,and satisfactory result of the experiments is gained.At the end,the effect of image recognition and calibration algorithm on the result is analyzed in detail. |
