摘要
在多投影仪曲面显示墙几何校正中需要用数码相机捕获图像反馈信息。为了方便准确地定位到每台投影仪的投影幕,提出并实现了一种数码相机自动定位的方法。该方法利用固定在云台上的数码相机获取图像,在对图像进行实时处理分析的基础上调整云台和相机参数。
In geometrical calibration for multi-projector display wall, there need to use digital camera to capture image information. In order to locate projection image of each projector conveniently and accurately. A new automatic location method of camera approach has been presented and carried out; this method utilizes platform and digital camera to capture image, basing on processing the image to adjust platform and camera parameters Real-timely.
