Description: Bundler是一个采用C和C++开发的称为sfm（struct-from-motion）的系统，它能够利用无序的图片集合（例如来自网络的图片）重建出3D的模型。最早的版本被用在Photo Tourism的项目上。
Bundler的输入是一些图像、图像特征以及图像匹配信息，输出则是一个根据这些图像反应的场景的3D重建模型，伴有少量识别得到的相机以及场景几何信息。系统借用一个由Lourakis 和Argyros提供的称为Sparse Bundle Adjustment的开发包的修改版，一点一点递增地重建出图像场景。Bundler已经成功的应用在许多网络相册系统，尤其是一些建筑相册里。
-Bundler is a structure-from-motion (SfM) system for unordered image collections (for instance, images from the Internet) written in C and C++. An earlier version of this SfM system was used in the Photo Tourism project.
Bundler takes a set of images, image features, and image matches as input, and produces a 3D reconstruction of camera and (sparse) scene geometry as output. The system reconstructs the scene incrementally, a few images at a time, using a modified version of the Sparse Bundle Adjustment package of Lourakis and Argyros as the underlying optimization engine. Bundler has been successfully run on many Internet photo collections, as well as more structured collections.

Description: 文介绍了如何使用Bundler来根据图片得到相机参数以及一些空间点云数据，得到的数据将能够运用在3D重建中。利用Bundler可以得到较为稀疏的点云（point clouds）数据。如果需要得到更密集的点，可以使用Yasutaka Furukawa博士写的另外一个非常强大的软件包，称为PMVS2。一种比较常见的途径是使用Bundler来得到相机参数，然后使用Bundle2PMVS程序，将生成结果转换为PMVS2的输入，然后使用PMVS2来得到更密集的点云。另外，读者们可能会对另外一个同样由Furukawa博士开发的实用工具——CMVS感兴趣，CMVS是一个场景聚类程序，在使用PMVS2前可以使用它来进行一些预处理。
