Digital Process for Rectifying a Photo of Cultural Assets

随着数码相机（CCD相机）分辨率的不断提高和成本的不断降低，数码相机的使用将越来越频繁。数码相机-个人电脑显示系统提供近乎实时的摄影。对一台成熟的CCD相机进行了标定。结果表明，定位误差较小，角度误差为80 ~ 130秒，但透镜畸变的影响较大。然后，需要非线性的方向参数来标定相机或重建光线。市面上的每一个图像处理软件都很有用。对于图像密度的插值方法，首选精确的插值方法。照相机、图像捕捉器和计算机技术正在进步。在这种环境下，图像格式的协调在处理系统中是必要的。

The steady increase in resolution and the decrease in cost of a digital camera (CCD camera) will result in frequent use of such a camera. A system of digital camera-personal computer-display offers nearly real-time photogrametry.An amature CCD camera were calibrated. The result shows that the positioning error is fairly small, for example 80-130 sec. in angle but the influence of lens distortion is serious. Then, non-linear orientation parameters are necessary for calibration of the camera or reconstruction of rays.Every software for image processing which is on the market is useful. As to the interpolation method of image densities, a precise method is prefered. Techniques on cameras, frame grabbers and computers are progressing. In this environment, coordination of the image format is necessary in the processing system.
