I am trying to do image processing on my arm board. But, I found that the performance of image processing is very poor. The processing time is about 3s in 1 frame. So, how to improve the performance of the processing? I don't know what the problems cause the bad performance. May be program, hardware or software. Does anybody use arm board to do image processing? I attached to a Qt code.
hey I am also trying to do the same thing. Can u tell me which webcam are u using?
Hi! Did you managed to have opencv working on ARM ? I compiled it but it always abort with illegal instruction. Thanks
Can this work at all? Illegal instruction sounds like floating point. The factory default kernel has no floating point emulation, the ARM CPU no CoProcessor inside and on the board ist no CoProcessor. At least, compile your own kernel with floating point emulation activated. So can it run. The performance is a other question. skip
Hi Jason. I am new to openCV and ARM9 mini2440. I want to connect my usb web cam to board for image processing. would you please help me? WinCE 6 is installed on my board. should I install linux ? Regards
I come across ¨segmentation fault¨. Not even connecting to the webcam! I am using mini6410 board with Qtopia. Any body has suggestion for me please?
I've worked with OpenCV. I'm not sure what kind of image processing your trying to do, but when i made my images grayscale before being processed they were processed a lot faster. Hope that helps!
