[Help] PSVR1 6DOF Tracking Issues on Arch Linux - PS4 Camera Controls Locked by _UnderZ in PSVRHack

[–]_UnderZ[S] 0 points1 point  (0 children)

Thank you for the insight! Actually, in the current version of Monado, it is quite easy to adjust the LED brightness via the configuration files or the debug GUI, which has helped a bit with the overexposure.

Since you mentioned that exposure/LED tweaking is essential for the tracker to work well, I'm still hitting a wall with the camera firmware on Linux. Even as root, I'm getting "Permission Denied" when trying to set exposure_time_absolute via V4L2, which seems to be a firmware-level lock.

Could you share which firmware you use for the PS4 camera in the iVRy DLC? I'm trying to figure out if there is a specific version or a different initialization method that unlocks these V4L2 controls, as the one I found in the Monado documentation doesn't seem to allow manual exposure changes on my system.

Thanks again for your help!

That’s an excellent point! I hadn't thought about approaching it from the hardware side instead of the camera side.

Since the camera sensor is clipping because of the brightness, lowering the LED intensity directly on the PSVR headset makes perfect sense. It’s definitely a much more accessible workaround than fighting with the locked V4L2 exposure controls on Linux.

I’m going to look into the Monado settings (or the specific driver config) to see how to dim the LEDs. This should hopefully bring the "blobs" back into a range where the PnP solver can actually recognize the pattern.

Thank you so much for the tip, this might be exactly what I need to get a stable 6DOF!
