摘　　要：提出了基于相对深度计算的TIP(TourIntothePicture)技术.该技术根据图像的几何透视关系计算出场景的背景与前景的深度信息,实现从参考图像到TIP模型的连贯切换.通过对蜘蛛网格的修改,TIP技术实现了斜坡场景的漫游;同时将该技术运用于多个场景实现了多个场景的串联漫游.Tour into the picture （TIP） technique is an approach that can makes animation from one 2D image of a scene. Based on the previous research experience, the authors proposed a new approach--the TIP using relative depth calculation （RDC）. Based on the geometry projection of the input image, this approach can calculate the depth information of the foreground and background models, and switch smoothly between the reference image and TIP model. Moreover, through modifying the spider mesh, the TIP technique can be applied to a scene with slopes. In addition, the RDC method has been applied to multiple scenes, and made animation on these scenes.
