Using Lightburn under Linux (Ubuntu 1804):
Ok, so Camera Lens Calibration went great! I then moved in to Camera Alignment and that’s when things broke down. Looking at the Debug Log:
QMetaObject::connectSlotsByName: No matching signal for on_image_doubleClicked(QPointF&) isFisheye: false reading camera matrix 2508.5 0 0 0 2517.28 0 1623.54 1217.95 1 reading lens distortion matrix -0.0290124 0.0387347 -0.000149726 0.00170397 -0.0496154 (AppRun:22874): GStreamer-CRITICAL **: 21:16:43.336: gst_element_link_pads_full: assertion 'GST_IS_ELEMENT (src)' failed (AppRun:22874): GStreamer-CRITICAL **: 21:16:43.336: gst_object_unref: assertion 'object != NULL' failed Setting res: 3264 x 2448 CameraBin error: "GStreamer error: negotiation problem." CameraBin error: "Internal data stream error." CameraBin error: "Internal data stream error."
So LB is able to interact with the camera enough to do the lens calibration, so it feels more like a LB error than a gstreamer error.
Edit: Seems to be the same problem as given in Camera calibration in Linux thread.
Thanks in advance for any assistance you can lend!
