Abstract

A surveying instrument and method for accurately determining the distance to a target in the close range for a specific setup of the surveying instrument, where the central part of the received ray bundle is shaded by a component of the optical unit of the surveying instrument. When targeting on the target in an on-target state the accuracy of the distance measurement decreases in the close range due to spatial and temporal inhomogeneities of the beam profile. In some aspects the target is targeted in a misaligned targeting state, such that the reflected measuring beam impinges on a part of the detector surface, which is not shaded, thereby leading to an increased measuring accuracy.

Abstract

A method of providing an augmented view of a real world scenery and of an occluded subsurface infrastructure. An image is taken by a camera with an image sensor and image reference information comprising a camera position and a camera orientation. From three dimensional information of a subsurface infrastructure, a two dimensional projection on the image sensor is made by using the reference information. A projection position of an anchor element of the subsurface infrastructure being visible on the at least one image is compared with an image position of the anchor element. A difference between the image position and the projection position is compensated for matching and overlaying the two dimensional projection derived from the three dimensional information of the subsurface infrastructure with the at least one image and thereby providing an improved augmented view.

Abstract

A large-scale capital project simulator has a project modeler configured to model the project as a virtual model having cable trays directing cables across the large-scale capital project. The simulator also has a cable router to lay out cables across the virtual model of the large-scale capital project. Each cable has a laid-out cable length. The simulator also has a routing manager to determine optimized routes of the cables across the virtual model. In this case, each cable has an optimized cable length along at least one of the optimized routes. The routing manager formulates an effectiveness ratio for each cable, where each effectiveness ratio uses the laid-out cable length and the optimized cable length. A filter determines whether any of the effectiveness ratios exceeds a prescribed deviation amount. A model controller transforms the virtual model to identify cable(s) exceeding the prescribed deviation amount.

The system has a remapping unit configured to remap a user command for moving two links with respect to each other about a corresponding joint to a rotatory tool degree of freedom. The system then coordinates output signals, such that as a function of the remapped user command the tool is rotated within the associated rotatory tool degree of freedom, without the need that an operator coordinates underlying joint movements.

Abstract

A method of manufacturing a plurality of parts receives cutting instructions to produce a part based on a nominal model of the part. The method then drives a machine tool with the cutting instruction to produce a given part, and subsequently measures the given part with a coordinate measuring machine by measuring at least one particular feature of the given part. After measuring the given part, the method calculates an error of the given part by determining an initial deviation between the cutting instructions and the nominal model, the initial deviation being a function of the measured at least one particular feature of the given part and a corresponding at least one particular feature of the nominal model. The cutting instructions are then adjusted based on the error map to obtain updated cutting instructions, where the updated cutting instructions have a reduced deviation from the initial deviation with regard to the nominal model. The method then uses the updated cutting instructions to produce another part having a reduced error deviation from the nominal model.
