Get vehicle speed of detected object

Hello,
is there a simple possibility to get the speed of a detected vehicle by using VisionWorks functinons. I’ve looked up the documentations of “VisionWorks - Structure from Motion” and “VisionWorks - Object Tracker Reference”, it only says that there is a possibility to do that (“An interface for getting information on ID, location, speed, and status of the tracked object”) but not how to. For testing I would like to use the function in a Sample App and write the current speed to a log-file.

Hope you can give me some support, thank you!

Excuse me but I am still searching for a solution approach. Is there nobody who can give me some support?

Thanks!

Hello daicatho,

Could you please let me know the references above came from in NV documentation of VisionWorks?
I couldn’t find the references in NV documentation of VisionWorks. Thanks.

Hello,
I found it in the “NVIDIA_VisionWorks_Tracking_Reference/nvvwx_trk_docs/classObjectTracker_1_1TrackedObject.html” documentation for ObjectTracker::TrackedObject’s and it is named “An interface for getting information on ID, location, speed, and status of the tracked object.”

Hello daicatho,

Could you please check the doc version?
I couldn’t find your mentioned link in the VisionWorks doc.

Below are VisionWorks(version 1.6) links.

Hallo Steve,
it is not to find in the “normal” VisionWorks documentation. It is available in the “Structure from Motion” (Version: DRAFT 0.88 Release) and “Object Tracker Referenc” (Version: DRAFT 0.84 Release) documentation.
