How can the challenges identified in the MCD dataset inspire new research directions?

The challenges identified in the MCD dataset, such as domain shifts across different campuses, varying lighting conditions, and sparse NRE lidar data, can inspire new research directions in several ways. Researchers may explore novel algorithms to address these challenges effectively. For example, developing robust SLAM methods that can adapt to diverse environments with high accuracy could be a promising direction. Additionally, finding solutions for semantic segmentation on NRE lidar scans could lead to advancements in understanding 3D scenes captured by unconventional sensors. The need for continuous-time ground truth registration also presents an opportunity for researchers to innovate and improve localization studies.

What counterarguments exist against using continuous-time ground truth in robotics perception studies?

While continuous-time ground truth offers benefits like superior accuracy and flexibility for high FPS applications like AR/VR devices, there are some counterarguments against its use in robotics perception studies. One argument is the computational complexity involved in generating and processing continuous-time data compared to discrete-time ground truth poses or processed lidar scans. This increased computational load may limit real-time applications of certain algorithms that rely on this type of ground truth data. Another counterargument could be related to potential overfitting issues when using highly detailed continuous-time information, which might not always reflect real-world scenarios accurately.
