Remote visual inspection

Remote Visual Inspection or Remote Digital Video Inspection, also known as RVI or RDVI, refers to a specialty branch of nondestructive testing (NDT). RVI/RDVI is an enhanced visual examination method that facilitates acquisition of visual data by means of visual aids including but not limited to video borescopes, push cameras, pan/tilt/zoom cameras and robotic crawlers. It is commonly used where distance, angle of view and limited lighting may impair direct visual examination or where access is limited by time,financial constraints or atmospheric hazards.

RVI/RDVI is commonly used as a predictive maintenance or regularly scheduled maintenance tool to assess the "health" and operability of fixed and portable assets. RVI/RDVI enables greater inspection coverage, inspection repeatability and data comparison.

The "remote" portion of RVI/RDVI refers to the characterization of the operator not entering the inspection area due to physical size constraints or potential safety issues related to the inspection environment.

Tools

Common tools used for RVI are as follows:

Applications

Typical applications for RVI include:
