Ask for the frame rate for Leap Motion Controller!

[diamondvu]

Dear all,

I am trying to use Leap Motion to read raw Images. But I see that the frame rate is very slow. For example, when I read a raw image I assigned and printed a time stamp to window console like this:

while (true)
{
Leap::ImageList images = controller.images();
time_t timestamp_lm = time(0);
cout << "timestamp leap motion: " << timestamp_lm << endl;
.....
}

However, the timestamp is printed in screen with low rate as the video below:

I guess that the frame rate is around 20-30 Hz. So do you know to increase frame rate for Leap Motion? and How to increase the frame rate?

Thank you so much for your help!

Best Regards.

That's incredibly slow. Is it that slow if you run a demo? What are your system specs?

Dear AlexColgan,

I just read raw images from Leap Motion, and print time stamp. I haven't processed any thing.
I don't know why it is very slow?
Do you know to increase frame rate for Leap Motion? and how to increase the frame rate?

Please help me!

Many thanks,

[AlexColgan]

Is it that slow if you run a demo? What are your system specs?

[diamondvu]

what do you mean " system specs" ?
Yes, I am running the demo to read raw images form Leap Motion cameras. But I see that the frequency to read Image of Leap motion is very slow about 20-30hz as you can see the video. Do you know why the frame rate to read image is very slow? and how to increase the frame rate?

Processor, graphics card, operating system.

You need to try another demo, such as the VR Visualizer, which can be found by right-clicking the taskbar icon.

Hi Alex Colgan,

I am running in the system with Window 10 - 64 bit, processor: Intel Core i7-6700 CPU @ 3.40GHz, Ram 16 GB, graphics Card: 6 GB.

I tried by using VR Visualizer and it shown as the photo below. The data frame rate about 110 Hz. However, do you know when I tried the application that just read raw image and print a massage to screen then the rate is very slow?

[diamondvu]

And do you know how to know exactly the data frame rate on the application? Do we have an API to show it?

[AlexColgan]

The application that is reading raw images is not pulling frames at a sufficiently high rate. This means that the problem is not with the sensor, but with the Visual Studio project.
