【摘要】 根据透视投影和三维变换的基本原理,导出了一个在参考图像和新视图之间建立联系的公式,并进一步放宽对相机的要求。只需要视点不动,从参考图像恢复出相机的内部参数和运动参数,并提出了参数的估计方法。任意方向的视图都可以使用这个公式直接从参考图像里无失真地投影出来。更多还原

【Abstract】 The rendering of Complex scene is important in Virtual Reality System.There are two ways in realizing the virtual scene:3D gaphics and Image based model & rendering.And an image based model & rendering is a novel technique.Based on the theory of perspective projection and three - dimensional transformation,we have gotten a formula which builds the relationship between a reference image and a new image,and releases the de- mand on a camera,only if the view point is constant,the inner parmneter can be restored from the reference im- ages,and the method of estimating parameter is provided.The image in Random direction can be rendered by the formula.更多还原
