Experience the Double Rate GigE camera series from D1312 Rauscher has an internal FPGA additional modulator, which reduces the image data in real time by a factor of approximately 2. With this particular data reduction, the signal / noise ratio of the images obtained at the same time, the frame rate is increased while maintaining the same resolution.
This achieves the DR1-D1312 CMOS camera at a speed of 135 frames / s at full resolution of 1.4 megapixel (equivalent 200 MB / s data volume) over a GigE link. Double the rate technology is compatible with 100% GenICam and GigE Vision.
CMOS cameras have gained acceptance due to its very high frame rates in the field of high-speed image acquisition and analysis. So far, high-speed CMOS cameras as compact camera heads with internal image storage or as a remote camera heads with Full Camera Link interface and frame grabbers are implemented with large memory requirements.
For applications including motion analysis as issues of bionics, sports medicine, biomechanics, and for the analysis of process disturbances such as the breaking of tools, disruptions in handling systems and packaging machinery frame rates are required, which are now covered more and more of high speed CMOS standard cameras for industrial image processing. Preference should be used for transmission distances and the resulting flexibility industrial cameras with standard GigE interface and twice as fast recording systems cameras with GigE interface and link aggregation in conjunction with recorder systems.
For the applications described Photonfocus has developed the double-rate (DR) camera technology that is built entirely on the default implementation of the GigE interface and the standard software protocols GenICam and GigE Vision, but nearly double the bandwidth provides. Thus standard tools and standard libraries of machine vision for the realization of high-speed imaging systems are used. The construction of multi-camera systems can be implemented easily, since the GigE standard is not left as the point to point connection of the link aggregation.
Thus, the disadvantages of systems that are based on cameras with Link Aggregation, from the outset to be avoided. It will be provided to the user selectable frame rates of over 577 fps @ VGA resolution and fps @ 204 960 x 960 pixels available. The major applications for sound barriers 500 fps at VGA resolution and 200 fps at megapixel resolution to be broken. Thus Photonfocus is again the leader in fast transmission systems. The double-rate (DR) camera technology is 25% faster than conventional Camera Link Base cameras and 100% faster than standard GigE cameras.
Another advantage of the modulation technique is used, the true format storage of the image data. The storage requirements for image sequences is almost halved, which together with the faithful storage format allows fast searches in the sequences.
Often in image analysis systems NIR markers are used during image acquisition. This is particularly the high quantum efficiency of the employed in the DR1-D1312-200-G2-8 A1312 NIR sensor of interest. For applications that operate in the NIR, the optimized for NIR sensor A1312IE be used in the cameras.
