An example system for detecting pipe defects is provided. The system includes a transmitter, a receiver and a processing device. The transmitter is oriented to transmit Terahertz (THz) waveform pulses towards at least one of an outer surface of a pipe or an inner surface of the pipe. The receiver is oriented to receive reflected Terahertz (THz) waveform pulses from at least one of the outer surface of the pipe or the inner surface of the pipe. The processing device configured is to receive as input the Terahertz (THz) waveform pulses transmitted from the transmitter and the reflected Terahertz (THz) waveform pulses received by the receiver and, based on the received input, determine if a defect in the pipe exists.

The present invention relates to a weld bead inspection device that inspects welding quality by measuring the state of beads formed at a welding part of a metallic or non-metallic pipe, or the like, and more specifically, to a weld bead inspection device that more efficiently inspects a welding part joined by a method such as thermal fusion for connection between pipes or connection between a pipe and a fitting. The weld bead inspection device includes a housing unit that forms an appearance; an imaging unit that images shapes of the weld beads in an inner space that is open downward from a middle inner side of the housing unit; a control unit that is provided in the housing unit to store image data captured by the imaging unit or to calculate external shapes of the weld beads for determining welding quality on the basis of the image data.

Method and arrangements for inspection of a drinking straw (101; 201) involving use of the drinking straw (101; 201) as a light guide for inspection of a sidewall (102; 202) of the drinking straw (101; 201) based on light leakage of guided light out from the drinking straw (101; 201) via the sidewall (102), such a through a damage (204) in the sidewall (102). It is illuminated (601), by means of one or more light sources (123), a first portion (131) of the drinking straw (101; 201) so that at least some of the light (127) on the first portion (131) is transmitted through a sidewall (102; 202) of the drinking straw (101; 201) into the drinking straw (101), and is guided therein. It is provided (602) one or more digital images (241) imaging another, second, portion (133; 233) of the drinking straw (101; 201) during said illumination. A light pattern captured by said one or more digital images (241) is analysed (603), corresponding to light escape of the internally reflected light out from the second portion (133) of the drinking straw (101; 201) via a sidewall (102; 202) of the drinking straw (101; 201). The damage (204) may be detected as a local spot (243) of image data discrepancy.

A rope tester to ascertain the condition of a wire rope in advance without increasing workload, Including a magnetization detector having a magnetizer for generating a magnetic force, and a detector for detecting a change in magnetism produced in a wire rope magnetized by the magnetic force generated by the magnetizer; a digital camera, which is provided a predetermined distance away from the magnetization detector along the traveling direction of the wire rope, for imaging the wire rope; and a controller, which is connected to the magnetization detector and to the digital camera, for detecting the location of a defect in the wire rope based on a change in magnetism detected by the magnetization detector, and outputting a drive signal that actuates the digital camera at a timing at which the defect location arrives at the location at which the digital camera is installed.

A computer-implemented method of automatically generating inspection templates of a plurality of known good fasteners to identify fasteners at an inspection station is provided. The method includes providing a data entry mechanism to provide content needed to identify a plurality of unidentified mixed fasteners. The method also includes storing the content in a database, extracting the content from the database and creating the inspection templates from the extracted content. Each of the templates including a fastener profile and a set of features. Each of the features includes a range of acceptable values. Each of the templates has a fastener identification code associated therewith.

Cameras and lights positioning system for hose inspection during air-to-air refueling, which comprises a substructure that can be attached to a container or capsule or Pod, one or two guidance-substructures (13) that enclose the hose, a toroid volume, to house the cameras (22) and lights (23) and a cameras and lights control subsystem. The system allows for the cameras (22) and lights (23) to maintain a fixed relative position with respect to the hose (1) during moments of imagery acquisition, despite the inclination and the five different movements that the hose has and makes, at the same time allowing protuberances (38) to pass through the system.

Systems and methods for creating a digital twin of an infrastructure component. The digital twin is a computerized, three-dimensional model of the component, typically a pipe, created after manufacture but before installation. The digital twin can be saved on a computer-readable storage medium for later retrieval, and can be loaded into three-dimensional modeling software for manipulation and viewing from various angles and perspectives. The twin is created from a plurality of imaging systems capturing different surfaces or different aspects, whose measurements are mapped to a uniform coordinate system to generate a three-dimensional model. Other data may also be added to or stored with the digital twin, such as manufacturing specifications, photographic data, and current or historical inspection data. The digital twin may be viewed on a mobile device programmed to receive, display, and allow the user to view and manipulate the digital twin.
