Hi everybody !!
I trying to get the xVel and yVel using opticalFlow, but I get an error on this line on my loop (first iteration) :
float xVel = cvGetReal2D( opticalFlow.vel_x, pY, pX);
pY and pX are on the range of my camera input (i have checked the values …)
but i get this error :
process returned -1073741819
The error must be caused by “opticalFlow.vel_x”, how can i trace it on my loop ?
any ideas ???
Thanks you so much !
