Bundler is a structure-from-motion system for unordered image
collections (for instance, images from the Internet). Bundler takes a
set of images, image features, and image matches as input, and
produces a 3D reconstruction of the camera and (s

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
