Re: Camera placement

<t>Hi<br/> One technique I've developed is to do a ball park placement of the cameras, to get the coverage I'm looking for.<br/> Then I'll place a marker in each corner of the anticipated floor space. Then I'll put one in the centre of the floor. Finally I'll use a tripod and extend it to the height...

Re: get_Tracking

<t>Hi<br/> <br/> Found the problem, it appears you still need to do a free/reset on the frame. It still takes a couple of seconds before tracking starts once the clip is repositioned. I had moved the free /reset up to after I've retrieved the vector data. This seemed to improve camera performance.<b...

get_Tracking

<t>Hi,<br/> Just trying to add a little robustness to my app by checking for a valid Vector using inpvector3->get_Tracking( &myPval).<br/> Works great when startup with vector clip in view of Camera When the clip is removed from the field of view it causes myPval.bool to get set to False. And th...

Re: Modified win32 sample hangs

Hi,

I found with the new build of the SDK specifying a timeout value other than zero crashes the program.

Modified win32 sample hangs

<t>Hi,<br/> <br/> I've modified the win32 sample to report the vector clip data. After aprox. 10000 frames it hangs on the getframe().<br/> If at 9000 frames I stop then start the camera it continues on. Any ideas as to what's going on?<br/> I'm using NPVECTOR3 to get the vector data and also set th...

Re: OptiTrack sample videos and BVH files

<t>Hi,<br/> <br/> I'm impressed. Was there a problem with the head tracking?<br/> Or was the performer just watching himself/herself on the screen?<br/> Are the videos a real time playback of raw data or corrected?<br/> What types of tools will be available for post processing of capture data?<br/> ...

C120 cameras

<t>We have noted a significant image distortion in the optitrack C120 cameras (wider field of view). Do the vector routines take this into account when calclating the position of the vector clip?<br/> If not is it possible to apply a lens correction to the frame prior to calculating the vector?<br/>...

Re: Bad Support on C120 Drivers Installation

<t>You may have a USB 1 vs USB 2 problem. Have not used these cameras on USB 1 but our 4 cameras work fine from both desktops and laptops (Dell optiplex and Precision desktops and Dell M70 laptops.) All running win XP SP2. <br/> Make sure you let windows do its install thing after you install the SD...

Roll Pitch and Yaw

I was doing some testing with the new SDK and discovered the corrections I had put in to account for the Vector clip plane's rool pitch and yaw were no longer required.
Is this correct? How are you now reporting the vector clip orientation?

Thanks
Niall
