rate of vision acquisition

I'm using a USB camera to complete my vision acqusition. However, it's rate floats between 9~10 frames/sec, which cannot satisfy my experiment with acquisition rate beyond 25 frames/sec. How do I solve this problem?

Hi,

First, I suggest you to open MAX and check your webcam settings. You should set the "Video Mode" to the good resolution and framerate.

 

Then in the status bar you should check the actual acquisition and display framerate. Save your settings and go back to LabVIEW.

Also never forget that if you use image processing, you may decrease the framerate due to the use of your CPU (for instance, your saving function to BMP may take time depending on your HDD speed and decrease your framerate)

 

Regards

Thank you ! In fact, I had set the mode before and found that made no sense. In addition, even if I only applied the vision acquisition express without any other functions, the acquisition rate remain 10fps even lower. What has happened.
