2 Planning in existing Plants In revamp and expansion projects for existing plants, an accurate measurement is an important basis for all further design work. Today, the laserscan can replace elaborate manual measuring procedures which use measuring tape and folding rule. This measurement technology can capture highly complex plants with millimeter precision within a very short time. Anlagenplanung Particular advantages for brownfield projects: - avoidance of frequent on-site remeasuring - optimal use of available resources - piping prefabrication with very high fit accuracy - reduced occurrence of errors by collision avoidance - cost-effective project realization - reduced periods of down time

3 Measurement Technology The laser scanner works with a laser beam which is reflected from the object to the scanner. The distance is measured with millimeter precision by means of the phase difference between the emitted and received beam. A rotating mirror reflects the laser beam in the vertical direction and the rotation angle is registered simultaneously with the distance measurement. During the scanning the body of the laser scanner is horizontally rotated through an angle of 360. The horizontal angle is also simultaneously registered with the distance measurement. The distance, as well as the vertical and the horizontal angle result in a polar coordinate (δ, α, β), which is converted into a Cartesian coordinate (x, y, z). At each measurement point, the degree of reflectivity (from highly reflective to dull) and the color value (RGB) are additionally determined. laser mirror distance measurement vertical deflection horizontal rotation Modern laser scanners like the Focus3D from the manufacturer Faro are characterized by: - compact dimensions (240x200x100mm) - low weight (<5 kg) - high precision (±2mm per measuring point ) - extremely high velocity (up to 976,000 points/sec.)

Measuring Procedure The area to be scanned is covered by several scans which are independently performed. Each individual scan creates a point cloud with approx. 40 million measurement points.

4 Measuring Procedure The area to be scanned is covered by several scans which are independently performed. Each individual scan creates a point cloud with approx. 40 million measurement points. Prior to the scan, reference points in the scan are defined by placing indicators (small spheres or stickers) in the area to be scanned. All surfaces in the visible field as well as the marked reference points will be captured in the scan. The predetermined reference points are visible in multiple scans so that the scans can be linked (registered) to each other using the reference points to compute a coordinate transformation. Permanently marked reference points on site can be used later as a construction aid. Additionally, subsequent measurements can easily be made within the same coordinate system without any problems A tachymetric measurement of the reference points allows a tension-free registration. The precision of the registration over different platforms is in the millimeter range. It is also possible to create a reference to a local building coordinate system (georeference) with the help of the tachymetric measurement.

It is also possible to perform distance measurements and to determine 3-D coordinates in the point cloud using the viewer.

5 Preparation of the Point Cloud Data After checking, the individual scans are registered to each other. The registration results in a huge point cloud database with several billion points. This database can be displayed with special 3-D viewers. It is also possible to perform distance measurements and to determine 3-D coordinates in the point cloud using the viewer. Panorama Views These photorealistic views can be displayed and rotated through an angle of 360. Additionally, it is possible to zoom in and out, measure real-world distances, and query real-world coordinates. Furthermore, graphic and text mark-ups can be generated which can be easily transmitted to other project engineers.

6 The Point Cloud within the CAD Model The point cloud can be transferred directly to the CAD model which serves as an outline or as a pattern for further design work. The designer has the ability work on the model within the existing plant.. Scale views, transverse cuts and floor plans can be created rapidly without any further processing.

processed to simple surfaces and solids.

7 Generation of Solids The point clouds are cleaned up and filtered. The reduced data are analyzed by our internally developed program and fully automatically processed to simple surfaces and solids. The generated obstructions can be imported subsequently to your favorite CAD System. Subsequently the relevant elements are manually processed to obtain a final 3D model.
