Video based visual condition inspection is a technique used to inspect generally continuous assets (e.g. roads, pipework etc) where manual visual inspection would either be too time consuming or too inaccurate.
Video based monitoring of pipes is generally referred to as a CCTV inspection.
Roads can be inspected using this technique.
A video equiped vehicle will drive along roads (to be inspected) and video record all aspects of the road, including road surface, road defects, kerb & gutter, surrounding environment etc.
This information is then supplied to a desk top application (driven by a knowledgeable person) and the detailed condition (inspection) information is generally manually extracted and placed into electronic files.
These electronic data/files can then be used to determine the condition of the monitored assets (e.g. roads).
