Abstract
A system and method are disclosed for estimating camera motion and structure reconstruction of a scene using lines. The system includes a line detection module, a line correspondence module, a temporal line tracking module and structure and motion module. The line detection module is configured to detect lines in visual input data comprising a plurality of image frames. The line correspondence module is configured to find line correspondence between detected lines in the visual input data. The temporal line tracking module is configured to track the detected lines temporally across the plurality of the image frames. The structure and motion module is configured to estimate the camera motion using the detected lines in the visual input data and to reconstruct three-dimensional lines from the estimated camera motion.
