TuView – data analysis tool

TuView is a program for visualising and analysing data obtained by the TS2 and TS3 tunnel scanners. It is specifically tailored to the needs of test engineers and its functionality has been — and still is — developed in close cooperation with our clients. Since many of the functions available today were inspired by suggestions from our users, the program is easy and intuitive to use, allowing engineers to focus completely on the task at hand.

TV_funktionstasten — Tunnel inspections with TuView: easy operation and clearly designed function keys

Changes at the client’s request

SPACETEC continues to develop and support TuView. In response to the needs of our clients, changes and adjustments may be made at short notice.

The concept behind TuView is to enable virtual tunnel inspection using the recorded data. The program includes function keys that allow the user to control the direction of travel, search for a specific point, zoom in or display an overview. It also offers a positioning scale and the option to adjust brightness and contrast for improved analysis of individual areas.

Support for all data channels

TuView is designed to support all three SPACETEC TS3 channels and takes advantage of the pixel-by-pixel synchronicity of the recordings. Anomalies in one channel can be identified with the support of the others.

Since 2018, RGB data from the SPACETEC TS4 have also been included in the display.

vierkanal5 — 4 synchronous data channels at a glance

TV_3d_clmap — Clearance profile map in 3D and as a development for both tracks

3d_zoom_v3_sehr_scharf — 3D zoom view for analysing surface damage

Analyses and clearance assessments

Record findings with markers and notes
Compare images from different years
Generate a clearance profile map to determine the position of constrictions relative to any specified clearance or target profile
Generate a clearance profile map with freely selectable colours and critical distances
Set theoretical profiles (clearance profiles or target profiles) as needed
Use dynamic clearance profiles
Simulate changes in track position
Generate minimum or maximum profiles
Calculate volumes (e.g. excavation volumes, filling volumes)

Exporting and printing

Export images as TIFF files or bitmaps
Select profiles and print or plot
Select profiles and export to DXF for CAD programs
Select profiles and read out/export the measured coordinates as XY values
Produce books of images using the print function (serial printing)
Use “print screen” function
