Visual inspection is a common method of quality control, data acquisition, and data analysis.Visual Inspection, used in maintenance of facilities, mean inspection of equipment and structures using either or all of raw human senses such as vision, hearing, touch and smell and/or any non-specialized inspection equipment.
An Automated Optical Inspection device. Automated optical inspection (AOI) is an automated visual inspection of printed circuit board (PCB) (or LCD, transistor) manufacture where a camera autonomously scans the device under test for both catastrophic failure (e.g. missing component) and quality defects (e.g. fillet size or shape or component skew).
PASER uses visual inspection to evaluate pavement surface conditions. When assessed correctly, PASER ratings provide a basis for comparing the quality of roadway segments. [1] The PASER assessment method does not require measurements of individual distresses, and thus PASER ratings cannot be disaggregated into measurements of specific distress ...
Visual inspection (VT), the most commonly applied NDT method, is quite often enhanced by the use of magnification, borescopes, cameras, or other optical arrangements for direct or remote viewing. The internal structure of a sample can be examined for a volumetric inspection with penetrating radiation (RT), such as X-rays , neutrons or gamma ...
Visual Inspection - Primarily using cameras to detect broken or cracked joint bars in bolted rail. Liquid Penetrant Inspection (LPI) - used for manual inspection of joint bars and rail ends. Eddy current inspection - great for surface flaws & near-surface flaws; Magnetic Particle Inspection (MPI) - used for detailed manual inspection
Task B: Visual inspection performed swiftly, recovery factor HEP=0.001 EF=3; Task C: Initiate standard operating procedure HEP= .003 EF=3; Task D: Maintainer hook-up emergency purge ventilation equipment HEP=.003 EF=3; Task E: Maintainer 2 hook-up emergency purge, recovery factor CHEP=0.5 EF=2
Inspection may be manual, conducted by an inspector using imaging equipment, or automated using machine vision. [citation needed] Since the similarity of materials between weld and workpiece, and between good and defective areas, provides little inherent contrast, the latter usually requires methods other than simple imaging.
Remote Visual Inspection or Remote Digital Video Inspection, also known as RVI or RDVI, is a form of visual inspection which uses visual aids including video technology to allow an inspector to look at objects and materials from a distance because the objects are inaccessible or are in dangerous environments.
