Abstract
Described herein are systems and methods that involve abnormality detection and a carefully designed state machine that assesses whether mapping, such as simultaneous localization and mapping (SLAM) processing, should be skipped for the current image frames, whether relocalization may performed, or whether SLAM processing may be performed. Thus, embodiments allow mapping processing to timely and smoothly switch between different tracking states, and thereby prevent bad tracking status to occur.
