Hello, I have a ZWO ASI 183MM camera, the protocol for acquiring the data is by calling a function repeatedly over a loop. But the problem is that the FPS is quite low in my case. I have attached the data acquisition part for it, I believe that can be improved by utilizing a Circular Buffer. Can anyone suggest me, how can I implement it in my case.
The Code:
long lBuffSize= height*width;
unsigned char *pBuffer= (unsigned char *) malloc(lBuffSize) ;
double *imBuffer= (double *) malloc(lBuffSize*8) ;
ASIStartVideoCapture(cameranumber);
Timer();
int q=0 ;
while(1)
{
exposurestatus=ASIGetVideoData(cameranumber, pBuffer, lBuffSize, exposure*2+500);
value=0;
if(exposurestatus==0)
{
ConvertArrayType (pBuffer, VAL_UNSIGNED_CHAR, imBuffer, VAL_DOUBLE, lBuffSize);
MaxMin1D (imBuffer, height*width, &maxvalue , &maxvalloc ,&minvalue , &minvalloc);
for (int i=29; i>=0; i--)
{
colors[i].dataValue.valDouble = (double)(value);
value = value + ((maxvalue - minvalue) / 29.0);
}
PlotIntensity (panelHandle_2, VIDEOPANEL_GRAPH, imBuffer, width, height, VAL_DOUBLE, colors, 0xffffff, 30, 0, 0);
}
