A method for inspecting a pillar-shaped honeycomb structure includes steps of: capturing a pattern of reflected light from an end face with a camera and generating an image data of the pattern of the reflected light; distinguishing positional information of each of cells adjacent to an outer peripheral side wall and cells that are not adjacent to the outer peripheral side wall based on the image data of the pattern of the reflected light, and storing the distinguished positional information in a memory; capturing a pattern of transmitted light from the end face with the camera and generating an image data of the pattern of the transmitted light; measuring intensity of each transmitted light from the cells adjacent to the outer peripheral side wall to detect the cells having defective plugged portions that are adjacent to the outer peripheral side wall based on the generated image data of the pattern of the transmitted light and the positional information; and measuring intensity of each transmitted light from the cells that are not adjacent to the outer peripheral side wall to detect the cells having defective plugged portions that are not adjacent to the outer peripheral side wall based on the generated image data of the pattern of the transmitted light and the positional information.

An Inspection apparatus (9) for inspecting cylindrical metal formed parts comprises a guide (11) for guiding the metal formed parts to be inspected through the inspection apparatus (9). The inspection apparatus (9) further comprises a radiation device which is adapted to emit radiation in the direction of the guided metal formed parts, so that the radiation impinges on each of the metal formed parts and is at least partially reflected therefrom as reflection radiation. A sensor device of the inspection apparatus is adapted to receive the reflection radiation and convert it into image data. An evaluation device is designed to assess, based on an evaluation of the image data, whether the respective metal formed part has production-related defects.

A system and method for coating marine pipeline weld joints and wet inspection of the applied coating is provided. The coating system includes an anti-corrosion coating including a fluorescent pigment to enhance inspection of the applied coating. The system also includes a robotic crawler for traversing inside the pipe and carrying a coating apparatus and inspection apparatus respectively configured to apply the coating on the weld joints and facilitate inspection of the wet coating. The coating apparatus comprises a spraying nozzle provided on a forward end of the robotic crawler and configured to spray coating onto on the surrounding circumferential pipe surface. The inspection apparatus includes an ultraviolet radiation emitter for activating the fluorescent pigment in the coating and a camera for providing a live image feed of the coated weld joint area to an operator computing station for inspection of the applied coating.

A position specifying section obtains an observation distance by specifying the position of an irradiated region from a picked-up image that is obtained from the image pickup of a subject on which the irradiated region is formed by auxiliary measurement light. An image processing section sets the amount of offset, which corresponds to a height of the irradiated region of a convex portion of the subject, for the observation distance, and generates an offset measurement marker on the basis of the offset distance that obtained by adding the amount of offset to the observation distance. A specific image in which the offset measurement marker is superimposed on the picked-up image is displayed on a display unit.

The present disclosure relates to technology configured to enable fault detection and condition assessment of underground stormwater and sewer pipes. Embodiments of the present disclosure have been developed to allow automated processing of video captured by pipe inspection robots and the like thereby to identify and categorize artefacts in pipes.

A detection device for a turbine blade of an aircraft engine includes a machine table, a fixing frame, a dip coating mechanism, and a detection mechanism. A sliding cavity is formed in an upper end of the machine table, a support plate is slidably arranged in the sliding cavity, a side end of the support plate is rotatably connected to a chuck, the fixing frame is in an inverted “U” shape and is fixed on the upper end of the machine table, and a mounting barrel is rotatably arranged on the fixing frame. The dip coating mechanism and the detection mechanism are arranged on the machine table, such that wall-hanging sediments in an air film hole and a cooling channel will be exposed to a first photosensitive camera and a second photosensitive camera through fluorescent liquid, thus completing wall hanging and blockage detection of the blade synchronously.

A method, apparatus, and system are provided to monitor and characterize the dynamics of a phase change region (PCR) created during laser welding, specifically keyhole welding, and other material modification processes, using low-coherence interferometry. By directing a measurement beam to multiple locations within and overlapping with the PCR, the system, apparatus, and method are used to determine, in real time, spatial and temporal characteristics of the weld such as keyhole depth, length, width, shape and whether the keyhole is unstable, closes or collapses. This information is important in determining the quality and material properties of a completed finished weld. It can also be used with feedback to modify the material modification process in real time.
