Remote Visual Inspection (RVI) is a long-established inspection and non-destructive testing technique in multiple industries. RVI is an evolving sector within non-destructive testing, and its key for organizations to stay up to date on the latest technologies and techniques in order to conduct the most accurate and efficient remote visual inspection. Below are key components to conducting more efficient RVI. USE AN INDUSTRIAL-QUALITY VIDEO BORESCOPE Industrial-quality equipment is designed to be rugged, durable, and deliver high quality images. Features include higher light output, environmental sealing, and drop specifications. The first step in any remote visual inspection is to obtain a bright, clear image of the region of interest. Defect detection and interpretation depends on image quality, which in turn depends on industrial-quality equipment. MAKING IT SIMPLE WITH SOFTWARE A shortage of skilled inspectors looming in the future of multiple industries, software solutions are extremely important when using a video borescope. Software is available to standardize inspection procedures to ensure consistency of both inspection and presentation of inspection results. Menu Directed Inspection (MDI) is a software solution that provides a guided inspection, where context is added automatically. All the identification data relevant to the task (inspector, site, date etc) is inputted before the inspection. The data image file is then tagged with annotations and filed within the borescope’s data capture system. A hard copy report is produced with a “click-to-report” feature. Software is key when it comes to sharing and storage visual images and its important The DICONDE (Digital Imaging and Communication in NDE) image standard is used to ensure long-term data utility and enables multi-modality communication. MEASUREMENT INCLUDED The measurement of flaws, discrepancies and clearances is just as important as their detection and identification; however measurement remains one of the most difficult aspects of using a video borescope. Measurements gathered by the commonly used stereo or shadow measurement technique are depth, length, area, point-to-line, multi-segment length and circle gauge. Operators must be highly trained and practiced to obtain reliable and repeatable results, which can slow down the overall inspection process. Recently, significant advances have been made in improving accuracy, repeatability and ease-of-use of video borescopes with the development of 3D Phase Measurement. This new technology provides accurate 3D surface scans using a single probe tip, saving time during the inspection process. Now a 3D scan can be captured rotated and zoomed to provide enhanced indication of the size and shape of the indication. CONCLUSIONS There have been many advances in remote visual inspection over the years. Image quality improvements, software and easy-to-implement measurement techniques can provide fast, accurate results with more comprehensive imaging to improve to allow smarter more efficient inspection.
