摘要： A point cloud of a tunnel is obtained. A cylinder is fitted using the point cloud of the tunnel. A central axis of the tunnel is extracted. A section of the tunnel is intercepted based on the central axis of the tunnel. Point cloud subsets of two rails are extracted. A base line of a contour of the tunnel clearance is constructed. A center of the section of the tunnel is extracted. A point cloud of the section of the tunnel is registered with a point cloud of the tunnel clearance based on a constraint condition. The point cloud of the section of the tunnel and the point cloud of the tunnel clearance which are registered with each other are analyzed to determine whether the tunnel clearance is intruded.

摘要： An apparatus, system and/or method for making observations down a wellbore are provided. The wellbore observation system may comprise a mandrel that can be run downhole, and telescoping tracks can be utilized to move a camera and semi-conforming inflatable bladder out of the mandrel and into the wellbore. Once the bladder is inflated, it displaces high turbidity fluid in the wellbore to allow the camera to move about a track and observe the wellbore unobstructed. An alternative embodiment allows the mandrel and telescoping tracks to be utilized with other tools to perform cleaning, fishing, diagnostic, and analytic operations.

摘要： An improved method and apparatus for determining wellbore position in deviated or horizontal wells. Continuous inclination values captured while drilling can be used to provide a more accurate model of a wellbore path, particularly true vertical depth, than would be produced using conventional methods of measuring inclination only at static survey points.

摘要： The present invention provides a direction finding system capable of positioning directions at two points, and particularly, for shifting a ground central base line and a reference point for tunneling work or the like to an underground tunnel shaft or the like, to position a digging thrust direction. A polarized light radiating device irradiates a body for the direction finding system with a polarized light beam or ray bundle and a direction difference detecting device provided within the body receives therein the polarized light beam emitted from the polarized light radiating device and detects the difference between the direction of the polarized light beam and a predetermined direction. A rotatory polarizing plate of the direction difference detecting device allows the polarized light beam to pass therethrough and a condenser lens gathers the polarized light beam transmitted through the rotatory polarizing plate. A light-receiving portion receives therein the polarized light beam gathered by the condenser lens and an encoder device detects a predetermined position and rotation of the rotatory polarizing plate.

摘要： The present invention relates generally to illumination devices and method of use in tunnel alignment. More particularly, the present invention relates to an illumination device producing a concentrated directional light beam adapted for verifying the center plane of a boring in an underground mine passageway. The illumination device includes a first elongated portion having a longitudinal axis. An arangement for fastening the first portion to a support is provided at a first end of the first portion. A second portion rotatably received by the first portion includes a light source for producing a directional light beam. The light beam is adapted to be directed away from the longitudinal axis of the first portion. An arrangement for retaining the second portion in a predetermined angular position with respect to the axis of the first portion is also provided. In a preferred embodiment, the second portion is telescopically received within the first portion and includes a hinge arrangement which permits pivotal movement of a holder for the light source relative to a segment of the second portion to a location substantially perpendicular to the longitudinal axis of the first portion.
