Methods and systems for restoration of lost image features for visual odometry applications

A system of analyzing an image captured from an imaging device, the system comprising:

• a receiving unit configured to receive one or more images captured from a camera over a predetermined time period;
• an execution unit configured to perform a feature extraction and tracking operation on the received images;
• a detection unit configured to detect one or more untracked features based on the feature extraction and tracking operation;
• and
• a prediction unit configured to execute a geometrical prediction to predict one or more tracked features from the untracked features.

A non-transitory computer readable medium storing code for analyzing an image captured from an imaging device, the code comprising instructions executable by a processor to:

• receive one or more images captured from a camera over a predetermined time period;
• perform a feature extraction and tracking operation based on the received images;
• detect one or more untracked features based on the feature extraction and tracking operation;
• and
• execute a geometrical prediction to predict one or more tracked features from the untracked features.
