Abstract:
In this paper we describe practical implementation of FPGA based solution for converting signal from cameras with HD-SDI, analogue and camera link interfaces to common HDMI format. Main challenges like: frame rate equalization, image resolution adaptation and acts in case of camera connec- tion loss are described in details. As a practical example we gave details about system with HD-SDI visible light camera, HD MWIR camera and analogue SWIR camera. In order to achieve target visibility in different day/night and meteorological conditions a multi-sensor imaging system combines signals from visible light camera, short wave infrared (SWIR) camera and medium (MWIR) or long (LWIR) wave infrared camera. Usually cameras originate from different vendor, with different interfaces, resolutions and frame rate. In order to enable further processing like image stabilization, enhancement, target tracking and image fusion, formats from all cameras should be con- verted to the same format.
