Photogrammetry: Systems, Software and Services

Optical 3D coordinate measuring devices and measuring services

The contactless measurement technology of photogrammetry is the reference for high-precision and cost-effective measurement in 3D. Photogrammetry calculates high-precision 3D coordinates from two-dimensional camera images. It is used in quality assurance, deformation analysis and dynamic measurements. Typical applications include the measurement of welded constructions or castings as well as the dynamic analysis of complex kinematics and deformations. Our customers come from plant engineering, foundry, aerospace, engineering and a wide range of other industries. As a specialist in optical metrology, we offer you all the services you need in photogrammetry:
  • Sales of optical measuring systems for static applications
  • Sales of optical measuring systems for dynamic applications
  • Development of customized hardware and software solutions
  • Measurement services and evaluation of complex data
We provide you with the exact 3D coordinates of an object either statically or dynamically over unlimited periods of time.

Optical 3D coordinate measuring devices for static tasks

Adapted to the needs of our customers we offer different systems for static measurements. The following application areas are particularly suitable for the close-range photogrammetry:
  • Quality assurance for components up to 20m size
  • Referencing of scanners
  • Roundness and flatness testing
  • CAD comparison and actual/nominal comparison
  • Static deformation analysis
  • Surveying applications for the craft
The Linearis3D Photogrammetry System is portable and easy to use. The measurement process is almost 100% automated. System components are a specially configured camera, a scale, measuring markers, carrying case and accessories. It weighs about 10 kg, and the system is so robust that it can be used in almost all industrial environments. We offer two different editions with the features that you need. This allows a cost-effective entry into the company's own optical measurement technology by photogrammetry. Various hardware options such as higher resolution cameras, special feature adapters or longer scales for large objects make the system even more flexible. A big advantage of photogrammetry is that it can cope with different lighting conditions, fluctuating temperatures and vibrations, without sacrificing precision. The application of the system is very simple. First, the desired measurement points are marked with self-adhesive or magnetic markers. Then a few dozen to a few hundred pictures are taken in quick succession. The evaluation is fully automatic by the software. With the extensive analysis functions, the required data can be generated quickly.

Dynamic Photogrammetry

Photogrammetry is excellently suited for the acquisition and analysis of complex dynamic processes. For 3D image acquisition or 3D video recording, two or more cameras are used, which are adapted in their optical resolution and the frequency range to the respective task. The optimal orientation and calibration of the cameras is flexibly selectable. We offer two dynamic photogrammetry systems:
  • Stereo: Dynamic deformation measurement for objects up to 10 m size
  • Video: Measuring coordinates at high speed
The results can be evaluated live or collected over an arbitrarily long period of time. Thanks to modern hardware our dynamic photogrammetry system can also be operated completely wirelessly. All measuring systems can be expanded as required by any number of (special) cameras (for example, higher resolutions or recording speeds). Just ask for an offer.

Measuring services from orthophoto to deformation measurement

If you do not have to carry out regular 3D measurements, we will support you in the needs-based measurement procedure by photogrammetry and the evaluation of the data. Our photogrammetry services include general measurement services and custom solutions. This includes:
  • Deformation measurements of objects under mechanical stress or climate change tests
  • Data acquisition for reverse engineering
  • Quality assurance
The procedure is individually adapted by us to the task at hand. We advise you in detail which measured values are important, set up the system and provide you with the data you need. Just call or write us.

Individual 3D image processing systems with the Linearis3D SDK

Using the Linearis3D SDK you can make your measurement application easily more powerful. We offer a wide variety of algorithms from 2D image analysis to determining the intrinsic camera parameters to camera orientation and adapter detection. Our image evaluation algorithms can detect an ellipse center with an accuracy of 0.03 pixels or better! We offer various algorithms for camera calibration, which can be configured depending on your application. Our software makes it possible to orientate an arbitrary number of cameras relative to each other. We can control these cameras using our vendor-independent SDK, trigger them synchronously and evaluate the data. Of course, we also carry out studies on specific tasks.

Seminars and training for optical metrology

We have developed several integrated solutions for scanners, cameras and software products. Get an overview on how to use the spectrum of photogrammetry hardware and software. Explore how to make the analysis of your data more efficient. As part of our customer service we offer seminars and trainings on individual products and methods of photogrammetry.

Explore the possibilities

For many industries photogrammetric 3D measurement methods are part of their daily routine. The deformation measurement is a prime example how photogrammetry can lower costs and create insights that would not be possible with other technologies. But many companies and some scientific institutions might not yet have evaluated how much they can benefit from photogrammetry. From industry to medicine to skilled crafts and trades, there are countless opportunities where the new digital methods can deliver rewarding discoveries. Please contact us!
