Abstract
Abstract A method and apparatus for determining the position of a pressed-ahead hollow-section line, especially with any desired three dimensional curvature, and having measuring points permanently and securely arranged in the hollow-section line. The three dimensional position of the measuring points, e.g. signal emitters, is detected by automatic sensing devices e.g. cameras, having remote control or long-distance transmission, and being arranged in the hollow-section line.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
183 words
In a method for determination of position of a pressed-ahead hollow-section line which can provide spatial three-dimensional contortion therewith, the steps comprising: in the hollow-section line, providing an arrangement of fixed measuring points with spacing from each other; moving the measuring points along in the pressed-ahead direction with the hollow-section line; distributing the measuring points over the entire length of the hollow-section line; in the longitudinal direction of the hollow-section line, fixedly arranging several automatic sensing-detection devices in series over the entire length thereof and also moving these devices along the hollow-section line in the pressed-ahead direction; determining the spatial three-dimensional position of the measuring points relative to each other via the sensing-detection devices; in the longitudinal direction of the hollow-section line, measuring the distances of the sensing-detection devices to the respectively next sensing-detection device and the distances of the measuring points to the respectively next measuring point; from the output signals of the sensing-detection devices and the measured distances, calculating a closed distance line, extending over the entire length of the hollow-section line and thereby determining the position of the hollow-section line.

In a method for determination of position of a pressed-ahead hollow-section line which can provide spatial three-dimensional contortion therewith, the steps comprising: in the hollow-section line, providing an arrangement of fixed measuring points with spacing from each other; moving the measuring points along in the pressed-ahead direction with the hollow-section line; distributing the measuring points over the entire length of the hollow-section line; in the longitudinal direction of the hollow-section line, fixedly arranging several automatic sensing-detection devices in series over the entire length thereof and also moving these devices along the hollow-section line in the pressed-ahead direction; determining the spatial three-dimensional position of the measuring points relative to each other via the sensing-detection devices; in the longitudinal direction of the hollow-section line, measuring the distances of the sensing-detection devices to the respectively next sensing-detection device and the distances of the measuring points to the respectively next measuring point; from the output signals of the sensing-detection devices and the measured distances, calculating a closed distance line, extending over the entire length of the hollow-section line and thereby determining the position of the hollow-section line.
Claim 3
Dependent Claim
68 words
A method according to claim 1 further including steps therewith whereby at a starting location of the hollow-section line there is providing of measuring points which are the connection points for a prescribed, superposed, spatial three-dimensional fixed point network (coordinate system); and detecting these measuring points via the sensing-detection devices, whereby there is determining of the position of the hollow-section line in the spatial three-dimensional fixed point network.
Claim 4
Dependent Claim
50 words
In a method according to claim 1, said method including the steps of: arranging said measuring points in such a way as to make possible the formation of a spatial three-dimensional line network; and ascertaining the lines of said line network by permanently installed automatic distance-determining devices having remote control.
