中文摘要：

给出了一个基于图像序列的交互式三维建模系统．通过输入一段未标定的图像或视频序列，系统能够自动地恢复出摄像机参数；然后用户只需要在少量几帧图像上简单勾画出物体的形态结构，系统就能自动解析出多帧之间用户交互的对应关系，从而迅速、逼真地重建出场景的三维模型．该系统提供了点与线段的重建、直线与平面的重建、曲线与曲面的重建等功能，能够满足对现实世界中的复杂场景的快速高精度的重建要求．几组真实拍摄的图像序列的建模实验表明：该系统高效、实用，能够很好地满足实际建模需求．

英文摘要：

This paper introduces an image-sequence-based interactive 3D modeling system. Given an uncalibrated image sequence or a video, the system can automatically recover the camera motion parameters. After simply drawing strokes or curves along the shape of the scene object on a few frames, the system can analyze the user interactions and help making the correspondences among multiple frames. Then 3D models of the objects in the images can be accurately reconstructed. This system provides reconstruction tools for modeling primitives of points, lines, planes, curves and surfaces, etc. It can meet the requirements of rapidly reconstructing realistic 3D models for real-world complex scenes. Several real-world examples are presented to demonstrate the effectiveness and usefulness of the proposed system.
