Kitware, a leader in developing advanced computer vision technologies, today announces new Phase I SBIR funding from the
Sparse bundle adjustment (SBA) is a technique for refining 3D scene geometry and the parameters of relative camera motion using images taken from different viewpoints. This technique has existed since the 1950s, but it is only in the past decade that the computational resources required to perform large-scale spare bundle adjustment have become available and practical to use.
Existing open-source toolkits for SBA are slow and focus on large collections of unordered images. Significant optimizations can be made for SBA by exploiting properties found in aerial video, particularly temporal continuity. These optimizations are available at all stages of the camera calibration pipeline, from feature detection and matching to SBA itself.
With this new Phase I funding, Kitware will develop an SBA system targeted for aerial video that will produce state-of-the-art camera calibration accuracy in a fraction of the time compared to current unordered image collection software. A variation of the techniques developed under this project can also be used to construct a streaming SBA solution for live video. Furthermore, relaxation of the specific constraint that bundle adjustment accuracy be optimal over all images could enable real-time, streaming video feeds onboard military vehicles for intelligence, surveillance, and reconnaissance (ISR) systems.
To achieve these goals, Kitware will leverage its world-renowned computer vision expertise, algorithms, and open-source libraries to perform feature detection, feature matching, and sparse optimization.
“We’re excited for the opportunity to improve a well-known yet under-utilized functionality and make a significant impact on video analyst workflows,” said
