I am trying to design an eye-tracker in labVIEW using a webcam and I'm wondering if vision development module and imaq vision is sufficient for acquisition and processing of images in real-time.
Please go through the following article:
Mehrube Mehrubeoglu, Linh Manh Pham, Hung Thieu Le, Ramchander Muddu, Dongseok Ryu, Real-time eye tracking using a smart camera, AIPR '11 Proceedings of the 2011 IEEE Applied Imagery Pattern Recognition Workshop, 11-13 Oct. 2011, Pages 1-7, DOI: 10.1109/AIPR.2011.6176373
I hope you will get some help regarding your research problem.
i did real-time calculation in Matlab/Simulink. Labview and simulink are same program structure. I think You can get well results with high-performence computer. Because as labview program use microprocessor' s source. So if you assemble a high-performce PC you can.
Dear Prathiksha,
You need to determine, how critical the repeatability of the data processing cycles is. Even high performance PC may generate random latencies, as the system suddenly performs other activity. If the real time feature is critical, you may need a bit more sophisticated setup. You may find some insight into this issue here: http://bulletin.pan.pl/%2860-1%2983.pdf.
Good luck!
What kind of real time, do you mean ? In fact Labview and imaq vision can take a lot of time to process images. It depend of the processing you intend to do and the frame/s you want to use.
Yes. The two modules are sufficient to track the eye. Best of luck.
Repeatable performance requires the real-time modules from National Instruments:

What kind of acquisition system are you going to use (NI PCIe-1433 e.g.)? Which are the frame rate and the length of the sequence you want to save? These are the key points you should fix to precisely address your question. Best
