SDK, Opencv and Visual C++

Hello,

I own a ASI178MC camera, drivers installed ( directshow dirver had some issues on win10 x64 but i think it works ), got it working fine on SharpCap, Firecapture. I also got a background as a VB.net+SQL programmer so i'm pretty lame on 'real' programming, libraries, C++, dependencies, etc.

I've managed to use OpenCV (opencv_ffmpeg310.dll) on some basic object tracking C++ programs using my webcam. I need much higher FPS so i want to use 178MC instead of the webcam in the existing working program.

I'm not really sure what system variables are needed, what dependencies to add in Linker/Input/Additional D, or if some ASI dll's must be registerd/copied somewhere. What to include in the C source file #include <ASICamera.h>?

I presume that there are a few simple,logical steps, so please guide me to solve this.

Thank you.

What I did so far:

Enviroment variable PATH C:\ASI SDK\lib\x86

Project properties - Linker - Input - Additional Dependencies asicamera.lib

Source.cpp #include <ASICamera.h>

Error: Severity Code Description Project File Line Suppression State Error LNK1104 cannot open file 'ASICamera.lib

Hi, you can refer to the demo project contained in the SDK package.

cannot open file 'ASICamera.lib : it's because the linker can't find the library, you should edit Additional Library path and add the path of ASICamera.lib or add the path in Additional Dependencies for asicamera.lib, say C:\ASI SDK\lib\x86\ASICamera.lib

Hello Yang,

Thank you, the demo project runs fine, but in black and white.

How can i switch from b&w to full color? And the other issue: is there a way to bypass the 60 FPS limit?

I've also tried : IMG_RAW8 IMG_RGB24

setImageFormat(width, height, 1, IMG_RAW16)

Tried different IPL_DEPTH

pRgb = cvCreateImage(cvSize(getWidth(), getHeight()), IPL_DEPTH_16U, 1);

getImageData((BYTE*)pRgb->imageData, pRgb->imageSize, 20);

Thank you.

>How can i switch from b&w to full color?

setImageFormat(width, height, 1, IMG_RGB24)

pRgb = cvCreateImage(cvSize(getWidth(), getHeight()), IPL_DEPTH_8U, 3);

getImageData((BYTE*)pRgb->imageData, getWidth()*getHeight()*3, 20);

>And the other issue: is there a way to bypass the 60 FPS limit?

what do you mean, the max FPS of camera?

Thank you, i've got colors now. :)

In the output window of the demo program i get maximum 65 FPS (and loads of dropped frames), even with 5ms exposure setValue(CONTROL_EXPOSURE, 5 * 1000, false); Might be some OpenCV limitaton. Can't figure it out yet...

On SharpCap i got over 470 FPS.

mari

char c = cvWaitKey(1); // This causes the low frame rate ~65 FPS

switch (c)

{

case 27:

goto END;

}

If anyone interested this is a workaround for ~220 FPS:

Mat origImage, threshedImage;

cvNamedWindow("orig");

//..............................

int frameCounter = 0;

while (1)

{

origImage = cvarrToMat(pRgb);

if (++frameCounter % 10 == 0) {

imshow("orig", origImage);

waitKey(1);

}
