摘要

本文在前人工作的基础上,提出了一个交互式可视化系统,该系统可以分析场景结构的不确定性及其对不同多视图场景重建阶段参数的敏感性。给定一组输入摄像机和特征轨迹,基于体绘制的方法从重投影误差测量中创建一个标量场。所获得的统计、视觉和等值面信息提供了深入了解场景结构在结构计算阶段的敏感性,如帧抽取、特征跟踪和自校准。此外,用户交互允许以传统的数学方式实现这样的分析,而不需要任何视觉辅助。结果显示了不同类型的相机配置的真实和合成数据,并与以往的工作进行了比较。

Visualization of scene structure uncertainty in multi-view reconstruction
This paper presents an interactive visualization system, based upon previous work, that allows for the analysis of scene structure uncertainty and its sensitivity to parameters in different multi-view scene reconstruction stages. Given a set of input cameras and feature tracks, the volume rendering-based approach creates a scalar field from reprojection error measurements. The obtained statistical, visual, and isosurface information provides insight into the sensitivity of scene structure at the stages leading up to structure computation, such as frame decimation, feature tracking, and self-calibration. Furthermore, user interaction allows for such an analysis in ways that have traditionally been achieved mathematically, without any visual aid. Results are shown for different types of camera configurations for real and synthetic data as well as compared to prior work.
