A robotic device and method for inspecting a pipeline to assess metal loss, the presence of defects and corrosion effects. The robotic device is an inline inspection tool that can establish a positional address in the pipeline using known positional benchmarks. The robotic device comprises flexible electronic caliper sensors measuring pipe diameter and an elastic foam body to prevent seizing within the pipeline. A removable PCB enables interchangeable operation with in-kind devices of different diameters and/or with the computers, extracting and plotting the data. The method of measurement may use data fusion between different instruments and measurement methodologies.

A measurement device according to one embodiment of the present disclosure is a measurement device that measures a position of an annual part to be measured that is arranged at an opening edge of a hole formed in a member to be measured, and the measurement device includes: a probe that is displaceable in an axial direction; a holder that holds the probe; and a measurement instrument that measures displacement of the probe in the axial direction. The probe includes an inclined portion at an tip end of the probe, the inclined portion being inclined relative to a central axis of the probe at an angle equal to an angle defined between a central axis of the hole in the member to be measured and a horizontal plane in a state in which the member to be measured is mounted on the horizontal plane.

A wellbore caliper includes an actuator housing pivotally connected at one end to a well logging instrument housing and an actuator disposed in the housing and operable to extend and retract laterally extensible measuring arms.

A sensor is placed on a plate lowered into the hollow of the shaft and guided by taut wires between a lower attachment device and an upper motorized winder. The deformations, responsible for measurement errors and caused either by static deformations, produced by the weight or poor construction of the apparatus, or by vibrations, are to a large extent eliminated.

Provided is an information processing apparatus including: an input unit into which shape data of a surface to be measured including a plurality of recesses is input; and a setting unit that detects each of the plurality of recesses on the basis of the input shape data and sets, for the detected recess, a region to be removed including the recess.

An inner-wall measuring instrument includes: a placement surface on which an object to be measured is placed; a base relatively movable with respect to the placement surface in three axis directions orthogonal to one another; a touch probe that is disposed at a first position of the base and brought into contact with the object; an image probe that is disposed at a second position of the base and capable of imaging the object with a direction parallel to the placement surface being an imaging direction; a rotational drive unit that rotates the image probe around an axis extending in a direction perpendicular to the placement surface; a linear drive unit that moves the image probe in the imaging direction; and a calculator that calculates an offset amount between the touch probe disposed at the first position and the image probe disposed at the second position.
