Rollei


 

RolleiMetric CDW is the digital photogrammetric software package from Rollei Fototechnic.

High performance combined with simplicity of use and user-oriented functions set standards for photogrammetric multi-image evaluation.

 

Applications

Acquisition of as-built data in plant construction.

Traffic accident documentation, forensic science.

Engineering, architecture and archaeology.

Medicine and specialist applications.

 

Project management

All measuring tasks are project-oriented in the RolleiMetric CDW.

RolleiMetric CDW accepts image data from both digital and analogue photographic systems.

In the user-friendly editor, calibration data for a number of different cameras may be input and used within the same project. Also, the same camera may be used in a number of different projects.

The use of a template in configuring a project allows recurring measurements (e.g. torsion tests) to be worked on quickly and efficiently.

 

Image management

RolleiMetric CDW contains a project-oriented image management system.

RolleiMetric CDW displays thumbnail overviews at a user-specified resolution. During the analysis of a project, the image data is constantly refreshed on the screen. The computation and accuracy results are also shown on the screen related to an interactive graphical adjustment of the camera locations.

 

Image evaluation

The design of the measuring functions within RolleiMetric CDW facilitates image initialization, point measurement and acquisition of the object geometry.

RolleiMetric CDW provides automatic réseau cross measurement and image orientation from analogue metric recording systems. Additionally, semi-automatic measurement of signalised (retro-reflective/coded targets) points and automatic error tracking are both included in CDW.

Three-dimensional object acquisition allows the evaluation results to be displayed in the current photogrammetric image by super-imposition methods. Epipolar geometry is also integrated and super imposed on the image to assist the user in data collection.

 

Calculation

RolleiMetric CDW incorporates both the widely accepted NAWE_OPT multi-image orientation software and the RolleiMetric bundle adjustment software PROMPT with the integrated facility for simultaneous calibration of analogue and digital systems.

Advanced computing techniques provide a rigid analysis of the measurement data. For inexperienced photogrammetry users, the comprehensive automatic calculation of extensive and complex image bundles is easy to use.


CAD interface

CAD drawings are produced within RolleiMetric CDW, therefore no additional CAD-system is required. Using the CAD evaluation module in CDW, both 3D and 2D evaluation may be accomplished.

CDW delivers data in most popular CAD formats.

As a standard feature, RolleiMetric CDW permits data export as either a 2D or 3D DXF, in user defined planes or rotations.

Data transfer to Intergraph’s Visual Database is also standard.

 

RolleiMetric CDW versions

RolleiMetric CDW is available in the following versions:

Plus 750: Calculation of a maximum of 750 unknowns in the bundle adjustment

Extended: Calculation of unlimited image bundles.

All versions run on a Pentium PC under Windows 32 Bit operating systems.
