Real time hardware developed for image processing applications such as image enhancement, segmentation, image registration, pattern recognition etc, can not be thouroughly debugged and analyzed for its performance by using conventional test equipment. To cite an example, the hardware for image registration may be failing intermitently or the registration point may be drifting even when the scene and the sensor are static. There is no way of knowing whether the malfunction is due to input data or any noise glitches. Therefore, for evaluating real time image processing hardware, it is necessary to acquire image sequence data in real time and also capture the status of the tracker in real time. Test equipment like logic analyzer, microprozessor development system do not have the capability to acquire and store image sequences. General purpose data acquisition systems on the IBM PC compatible computer are not suitable as the data rate required is about 500 kbytes/sec. The design of an interface card for achieving this data rate using IEEE-488 (GPIB) interface is described. Results on the evaluation of image processing using this card are also presented.
