Vision-based navigation and positioning.
| Technology | Type | Advantages | Limitations |
|---|---|---|---|
| Monocular SLAM [45] | Visual-based | Lightweight, lower cost, works in shallow depths | Less accurate depth estimation, struggles in low light |
| Stereo SLAM [46] | Visual-based | Provides depth perception, more accurate mapping | Requires more computational power, sensitive to lighting conditions |
| Structure from Motion (SfM) [47] | Visual-based | Generates 3D maps from 2D images, useful for complex environments | Requires good quality visual data, computationally intensive |
| Deep Learning-Based Vision[48] | Visual-based | Automates damage detection, high accuracy | Requires large datasets, high computational cost |
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
