Disclosed herein are various embodiments related generally to computer vision, graphics, image scanning, and image processing as well as associated mechanical, electrical and electronic hardware, computer software and systems, and wired and wireless network communications to form at least three-dimensional models or images of objects and environments.

A method and apparatus is shown for measuring diameter of sucker rods during reworking of an oil well. Diameters are compared to known data tables to determine if a sucker rod should be replaced. If undue wear has occurred to the guides, the sucker rod will be replaced. If wear is excessive, additions guides will be added to the replacement sucker rod.

Disclosed herein are various embodiments related generally to computer vision, graphics, image scanning, and image processing as well as associated mechanical, electrical and electronic hardware, computer software and systems, and wired and wireless network communications to form at least three-dimensional models or images of objects and environments.

Methods and systems for capturing motion and/or determining the shapes and positions of one or more objects in 3D space utilize cross-sections thereof. In various embodiments, images of the cross-sections are captured using a camera based on reflections therefrom or shadows cast thereby.

A comprehensive information detection system for a steel wire rope, having a detection device, a stroke metering device, a data acquisition and conversion workstation, an alarm controller, and a terminal control master station is provided. The detection device further specifically has a steel wire rope electromagnetic detection device, a steel wire rope machine vision damage recognition device, a steel wire rope machine vision diameter measurement device, and a damage location marking device. The comprehensive information detection system for a steel wire rope may perform comprehensive evaluation on the damage situation of the steel wire rope and refine damage data information, thereby comprehensively improving the refinement degree of detection and the detection accuracy.

An installation (2) for optically inspecting containers (3) includes a support table (7) for containers, which table has a slide plate (8) on which the bottom of a container stands. The slide plate (8) includes a portion (18) that is movable under the action of an actuator (19) to move the movable portion (18) between a transfer position in which the movable portion is flush with the table, and an inspection position in which the movable portion (18) is set back relative to the slide plate (8). A light source (14) and a light sensor (15) are positioned so that, in the inspection position of the movable portion, the sensor can receive a light beam propagating in an inspection volume (V) in which there is situated at least a portion of the bottom (4) of the container spaced apart from the slide plate.

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.

A device for adjusting the setting of and/or for measuring a tool includes a measuring element carrier which can move along a first axis (x-axis), and along a second axis (z-axis) that extends at right angles to the first axis, on which measuring element carrier a measuring element for the optical measurement of the tool is disposed. To facilitate the adjusting and measuring process, a reference body, which is able to move between a standby position and a measuring position on the tool, is disposed on the measuring element carrier for interaction with the measuring element.

A device for measuring elevated areas of the surface of a rotary body in the form of a cylinder, a roller, a sleeve or a plate of a printing press, for example a flexographic printing plate, includes a first motor for rotating the rotary body about a rotational axis and a measuring unit for contactless measurement. The measuring unit for contactless measurement includes at least one radiation source and at least one area scan camera. The measuring unit for contactless measurement preferably includes a reference object, for example a wire tensioned in an axially parallel manner, a second motor and optionally a further second motor, for adjusting the measuring unit and/or the reference object perpendicularly to the rotational axis. The device makes it possible to measure elevated areas, for example flexographic print dots, quickly and with high precision. A system having the device is also provided.

An apparatus for non-contact monitoring of travelling objects being produced in an unguided linear process comprising: a toroidal structure with an open aperture defining a measuring zone, a source of radiation configured by a plurality of radiation devices circumferentially disposed within the measuring zone whereby the radiation source emits rays that generate a planar screen of radiation across the object circumferentially to envelop the object, a plurality of circumferentially disposed recording devices for receiving radiation from the radiation devices following interception of the rays by the objects, and analysis means for analyzing imaging information of the emitted radiation recorded by the recording devices thereby to provide a measure of the physical characteristics of the object.
