“…The upper left is the medium wave image, the upper right is the long wave image, the lower left is the image obtained by color transfer, and the lower right is the final fusion image with band difference enhancement processing. The source image is from the document [12] reported by Schreer O. et al It can be seen that the scenery such as ground, road and car located in the lower part of the image is relatively simple, and the band differences displayed are very easy to be observed. However, the scenery such as truck and building glass located in the middle of the image on the left is not easy to be found because of the complexity of the scene.…”

Dual-band MWIR/LWIR imaging technology has the advantages of the two bands, through complementary advantages, can improve the ability to adapt to complex environment, the recognition rate of different targets. In application, how to combine and enhance the information of the two bands and present better visual effects through image fusion is the key problem to effectively utilize the advantages of the two bands. Color fusion has become the main method of infrared image fusion because of the ability of human eye color vision to fully retain dual-band information. The false color fusion algorithm is helpful to improve the recognition accuracy, but the color distribution violating human visual habit will increase the reaction time. Natural color fusion can accord with human visual habits to the greatest extent but will weaken the infrared radiation characteristics and band differences. In this paper, an image fusion framework is proposed, which preserves and intensifies the band difference through the difference enhancement of false color, and achieves the color distribution close to the natural scene through color mapping. Simulation experiments are carried out for infrared medium and long wave images of different scenes. The results show that while preserving the spatial information of the two bands, the differences of the bands are enhanced and highlighted, and the color distribution of the fused image is close to the natural scene to a certain extent. It shows that the algorithm in this paper combines the advantages of the fusion of false color and natural color to some extent, and achieves the effect consistent with human visual habits as much as possible on the premise of enhancing the difference of band.

“…Thermosensorik established infrared cameras [13,14] and industrial NDT systems using digital technology and personal computer (PC)based equipment for real-time data acquisition and image processing without a DSP. This technology permits NUC calculations and image display in real-time at the full image rate of the camera being more cost-efficient than the common technology and more flexible in order to expand the systems for different applications.…”

This article presents strategies, implementations and applications of handling infrared FPA data streams at high data rates on most recent standard PCs. Those data streams require maximum data throughput of modern PCs. Real-time non-uniformity correction (gain and offset correction) of those high speed infrared FPA data streams will be discussed. The performance of PC based systems for Real-Time data Acquisition and data Hard Disk Storage (RT-AHDS) will be described in more detail. Some of the Thermosensorik systems for use in research and development, as well as in in-line testing systems in industry for various applications will be presented. This paper describes some of the demanding tasks for the PC based concept, as well as some major advantages.
