Today’s area scan cameras are able to provide lots of images at a high resolution. However, much of these data are not needed for further image processing. To reduce the data volume, this work can be done inside the camera. As an example, take three intelligent cameras set up to observe fast movements in sports, with the sportsman marked with white spots at important places like arms, elbows, hands or head.
Three cameras from different angles identify the white spots by image processing, and only transmit the spot coordinates to a central host computer. With the coordinates from the three cameras, a 3D model can be calculated by the host computer. Typically, the amount of data would be so great, that the data stream and the volume would be too large for a single computer. By reduction down to only the necessary coordinate data, the transmission and calculation of a 3D model is possible.
Even the reduction to 180 images at VGA resolution needs high processing power. This is provided by Basler’s eXcite, that has a fast camera and processing power comparable to a Pentium III at 800 MHz within small dimensions of 150mm x 55mm x 60mm. The eXcite houses these two high performance components in a very small package while maintaining 100 percent compatibility with standard PCs. With its compact size and versatile interface – including USB, Gigabit Ethernet, and digital I/O connections – the eXcite is well suited for a wide range of industrial purposes in a variety of contexts. Basler’s eXcite is a flexible, high-performance platform designed to handle the most demanding vision applications.
