1. A downhole inspection system, comprising:
a tool string lowerable into a wellbore;
a first imaging device forming at least a portion of the tool string, the first imaging device operable to generate first imaging data for detecting potential wellbore eccentricity anomalies, wherein the first imaging device comprises:
a first source operable to emit energy of a first non-optical modality towards a target; and
a first detector operable to detect returning energy from the target;
a second imaging device forming at least another portion of the tool string, the second imaging device operable to generate second imaging data for detecting potential wellbore anomalies, wherein the second imaging device comprises:
a second source operable to emit energy of a second modality towards the target; and
a second detector operable to detect returning energy from the target; and
a processor configured to:
receive the first imaging data and the second imaging data;
reshape the first imaging data and the second imaging data to a common size;
scale the first imaging data and the second imaging data to comparable intensity levels; and
combine the eccentricity anomalies from the first imaging data with the second imaging data to provide enhanced data for detecting wellbore anomalies.
