摘　　要：提出一种基于多个深度狭缝图像全景拼图的新的基于图像的绘制方法 ,可以进行大范围的基于图像绘制。本文首先介绍了深度狭缝图像和深度狭缝图像全景拼图的概念 ,在假设相机仅作平面移动的情况下 ,描述了利用深度狭缝图像生成原视点附近的近似场景和在多个深度狭缝图像全景拼图间作平滑切换的算法 ,并给出了从采样到绘制的实现。该方法具有采样简单 ,虚拟场景真实感强 ,支持连续大范围漫游的特点。文中给出了具体算法和实验结果 。Presented a new image based rendering (IBR)technology called rendering using multiple panoramic mosaics of slit images with depth (PMSID).The PMSID is a kind of panorama that combined by a set of slit images with depth. When the virtual camera moves around, slit images are scaled up and down to simulate the looming effect. This acceptable approximate method enables the virtual camera switch between PMSIDs smoothly, thereby can be used to construct a large IBR-based virtual scene. The authors presented the rendering algorithm based on multiple PMSIDs. PMSIDs are easy to capture, and their data size is small, this makes PMSIDs very efficient for IBR use. The authors also presented the capturing, construction and rendering process of panoramic slit images mosaic with depth.
