Interesting, it looks like it's an issue coming from the Anchor manager rather than the camera it self. The Error in the anchors might be causing a frame hang which then causes the camera image to miss a frame as well. Do you get the Anchor localization issues when the camera get pose function is di…

Oh I'm not using spaces. Not intentionally, anyway. It was too problematic. False positives, etc. The information I'm looking for here is really just the difference between the virtual and physical cameras pose. EG If the virtual camera is centered on the left eye display and slightly converged tow…

Do you mind sharing the Argyle.Risa.AnchorTech.ML2.ML2RPManager:GetLocalizationInfo() function? It may be calling MLAnchors:GetLocalizationInfo() which could result in the error code. The error then could be delaying the GetFramePose function from the camera causing the Camera function to fail.

I can share that function when I'm at my dev computer. It does seem to call that even though it shouldn't because I've cut off the use of Spaces. Must be left over from when I was trying to implement that tech. For clarification, if I'm not using Magic Leap Spaces, should I even be using MLCVCamera…

Yes the MLCVCamera.GetFramePose function is the correct one to use to get the post of the camera given a timestamp. The pose is relative to the origin, which is where the headset began tracking head pose. Since the frames are slightly delayed, using that function makes sure that they pose from the …

I’ve already accounted for delay. Does it also account for physical offset of the camera?

Yes, the Camera is calibrated at the factory so it will provide the most accurate pose. I strongly recommend continuing to use the GetFramePose call . If you were able to locate the previous MLAnchors:GetLocalizationInfo() logic and you are still having problems obtaining the CVCamera Pose please le…

Additionally, do you remind providing the OS and SDK version?

Update: I was able to start getting the pose by reducing the frequency of query. If I save out resultExtras.VCamTimestamp each time I capture an image, then when I want to do CV on a particular image, I do MLCVCamera.GetFramePose(_lastCaptureTimestamp, out Matrix4x4 cameraTransform) to get the pos…

I have that solution to the pose problem and it's working well. But as I attempt to close up this effort and move forward, I'm having possibly related issues with capture itself. I started a new thread for it:
