On Depth Error from Spherical Camera Calibration within Omnidirectional Stereo Vision (2022)
Presentation / Conference Contribution
Groom, M., & Breckon, T. (2022, August). On Depth Error from Spherical Camera Calibration within Omnidirectional Stereo Vision. Presented at 26th International Conference on Pattern Recognition, Montreal, Québec

As a depth sensing approach, whilst stereo vision provides a good compromise between accuracy and cost, a key limitation is the limited field of view of the conventional cameras that are used within most stereo configurations. By contrast, the use of... Read More about On Depth Error from Spherical Camera Calibration within Omnidirectional Stereo Vision.
