Re: Setting and understanding framerates V120

Hey Lamar, I have some observations and insight for you looking over your code. #1: In your while(1) loop, you will want to yield the thread to avoid the potential for wasted CPU. I would recommend a Sleep(1); or even a Sleep(0); at the end of your loop. #2: MJPEG mode is sending 120 VGA resolution ...

Re: Computer performance affected with SDK

This will not reduce CPU usage is not fully supported yet. When it's officially supported, it will likely only be utilized on some camera types.

Re: Setting and understanding framerates V120

Hey Lamar, Your code looks good. I don't see anything there that is suspect. This suggests the problem is somewhere else in your code, dependencies, or project setup. If you have a simple project feel free to zip it up and send it to support and I will take a look. As a test I suggest you open up on...

Re: Setting and understanding framerates V120

Hey Lamar, I think we all agree having the SetFrameRate() call map directly to FPS is the best way to do it. Our Ethernet camera devices all work in this fashion as well as the Flex 13 camera and they can be set to any value between 30FPS and the camera's maximum frame rate. However some of our USB ...

Re: Crash on Rasterize - how to fix?

Hey Lamar, The Frame::Rasterize function populates the buffer that you provide. It does this for speed so that you're not in a situation where Frame::Rasterize populates it's own buffer and then you're in situation where you need to do the expensive step of copying it where you need it. Now, the one...

Re: Visual Studio 2012 - getting up and running

Hey Lamar, Here is some information for you regarding the Camera SDK. First off, I think you missed one preprocessor that is important. In addition to CAMERALIBRARY_IMPORTS, you also want CORE_IMPORTS. This should get rid of the warnings you are seeing regarding Core::cUID. Secondly, the S and D suf...

Re: Computer performance affected with SDK

Hey maikelnai, I think you've demonstrated the while it's possible for Intel Atom based machines to utilize the Camera SDK, it's also very under-powered for this type of application. I don't have many suggestions for you if you're required to use this as your platform. Perhaps among the few options ...

Re: Computer performance affected with SDK

Hey maikelnai, Thanks for sending this over. When I compile & run this unmodified for either Debug or Release with my cameras in an attempt at a worst case scene (trying for hundreds of objects per camera) my CPU utilization barely tops 1% but most of the time it's listed at 0% (see attached). I thi...

Re: Computer performance affected with SDK

Hi maikelnai, This CPU utilization is unusually high. The Camera SDK is designed to be a very light layer and utilize the absolute minimum CPU in every possible configuration. If you create a synchronizer, attach your cameras, and do nothing else, you should expect that the Camera SDK will hum along...

Re: Object Labeling in the Camera SDK

I wanted to post a follow-up to this ticket regarding 2D labeling. The Camera SDK includes one useful module for 2D labeling: cModulePreLabel. This is the module you want for labeling 2D markers. It's the best offering from the Camera SDK. The way this module works is that it will track the trajecto...
