Re: CameraSDK-TrackIR5, rotation order, axis, unit

That is correct. There are differences in our Euler assumptions that impact the result. It's good that you are not relying on Euler angles for your project as you are already clearly aware of the pitfalls associated with them. I would recommend creating two vectors and generate your own orientation ...

Re: Convert Quaternion to Angles between 0-360

Hi Raedle, I apologize that your question went unanswered. In regards to your question specifically regarding the conversion of quaternion to Euler angles, I'm a bit unclear with the question and what you're trying to do. It sounds like this is more of a general question regarding the topic conversi...

Re: CameraSDK-TrackIR5, rotation order, axis, unit

Hi hwang. Here are some answers: 1) Degrees 2) yaw, pitch, and roll values are created from a 3x3 orientation matrix and then converted to degrees. The conversion uses an implementation described in detail here: http://www.euclideanspace.com/maths/geometry/rotations/conversions/matrixToEuler 3) I be...

Re: 2 Cameras and GrayScaleMode

Hi Alexis, Unfortunately reliable raw grayscale on our cameras is very difficult. When the cameras are running at the full frame rate, even though the aggregate data rate is well below the maximum throughput of the USB channel, the camera's has no mechanism to throttle the data based on USB congesti...

Re: Object Labeling in the Camera SDK

Thorsten, Thanks for testing all of our modules! I've ticketed moduleactivelabel.h issue as well. This module is a powerful one for the Camera SDK. If you attach it to a camera, it will track objects and label each one with a fixed label until it goes out of view or becomes occluded. modulepoorlabel...

Re: Object Filtering in Camera SDK

Hi Thorsten, The only way to filter objects on the camera is by using hardware masking. All other filtering is currently done after the data has been sent over USB. So basically, everything in cModuleObjectFilter is just on the software side. I agree with you that setting the filter parameters and a...

Re: Centroid calculation

The Camera SDK uses 'center of mass' of the blob. I would recommend using a full sphere diffuser.

Re: Motive 3D reconstruction

The distortion model is provided in the Camera SDK as a helper for the user. The distortion model is not applied to data coming out of the camera automatically. Typically you would fetch each X & Y coordinate from each camera's frame as you iterate through the objects. The easiest way is to use ...

Re: Marker Info

Motive and it's user interface is right-handed and the data presented is all in right-handed coordinates. Some of our streamed formats stream out in left-handed coordinates currently but they will all be right-handed in the near future. A simple rule of thumb for converting between left & right ...

Re: Motive 3D reconstruction

The Camera SDK only exposes a general distortion model that matches the default lens sold with the camera. Unfortunately, there is currently no access to the distortion model calculated during manufacturing. In regards to the discrepancy, I believe it is a difference between where the origin of the ...
