InfraTec together with the University of Stuttgart research new ways for compressing thermographic measurement dataInfraTec GmbH36, Dresden, Germany
The Intelligent Solution
When exchanging thoughts and ideas on the latest developments in thermal image and thermographic cameras, the discussions increasingly focus on the constantly growing data volumes. It is not without reason that events such as this year's Quantitative Infrared Thermography Conference (QIRT) include topics such as data reduction during image processing on the scientific agenda. InfraTec is following these discussions actively and contribute its own ideas on a regular basis. The latest discussions concern the compression of thermographic measurement data in real time.
Increasingly larger detector formats are leading to ever larger data volumes
Interfaces commonly used at present will quickly become a bottleneck here. For example, the GigE interface with a data rate of 1 Gbit/s noticeably limits the performance of thermographic cameras. Even a mass storage device integrated in cameras does not solve the problem. It deprives other components of valuable space, causes additional heat within the camera due to its power dissipation and only offers limited storage capacity. Moreover, the increase in the camera price is not insignificant.
Data compression in real time
Initial results show the direction in which the development can go. The team comprising scientists and practitioners has already been able to compress measurement data by up to 80 percent in comparison with the original size, without decisively losing image quality and measurement accuracy. There is still a long way to go here. The project will finally run until summer 2017. The collaborative work should then have progressed to such an extent that it will be possible to integrate the intelligent data compression into software solutions of InfraTec.
