Paper Abstract
Nowadays, high-speed imaging offers high investigation possibilities for a wide variety of applications such as motion
study, manufacturing developments. Moreover, due to the electronic progresses, real-time processing can be
implemented in the high-speed acquisition systems. Important information can be extracted in real-time from the image
and then be used for on-line controls. Therefore we have developed a high-speed smart camera with high-speed CMOS
sensor, typically 500 fps with a 1.3 Mega-pixels resolution. Different specific processing have been implemented inside
an embedded FPGA according to the high-speed data-flow. The processing are mainly dedicated to feature extraction
such as edge detection, or image analysis, and finally markers extraction and profilometry. In any case, the data
processing allows to reduce the large data flow (6.55 Gbps) and to propose a transfer on a simple serial output link as
USB 2.0. This paper presents the high-speed smart camera and focuses two processing implementations: the marker
extraction and the related profilometry measurement. In the marker extraction mode, the center of mass is determined for
each marker by a combination of image filtering. Only the position of the center is transferred via the USB 2.0 link. For
profilometry measurements, a simplify algorithm has been implemented at low-cost in term of hardware resources. The
positions of the markers or the different object's profiles can be determined in real-time at 500 fps with full resolution
image. A higher image rate can be reached with a lower resolution (i.e. 500 000 profiles for a single row image).
