Compass rose orientation

[h3ifri]

Hi Max!

I think the compass rose is off by 90°, the png points to west and not to north. It can be fixed by either rotate the png by -90° or in code:

@@ -851,3 +851,3 @@ public class Visualizer3D extends JFrame {
             dZ = -Math.atan2(m1.getElement(1, 0), m1.getElement(0, 0)) + Math.toRadians(90.0);
-            affTrans.setToRotation(dZ, halfW, halfW);
+            affTrans.setToRotation(dZ + Math.toRadians(-90.0), halfW, halfW);
             drawg2d.setTransform(affTrans);

Cheers,

Hi Heiko,

Are you saying it's off 90° in the actual HUD? I know the png image is rotated, that's so it doesn't need to be rotated in the code for every draw. The HUD has always looked correct to me...

Hi Max,

the heading indicator in the SIM did not match the heading in QGC. Rotating the rose by -90° fixed it for me. I assume that after an UKF reset, the ground camera should point north?

Heiko, this is not what you see after a reset (or at startup)?

I've never seen what you describe... do the AQ mag inclination/declination settings match what the sim is reporting (besides the inclination being reversed)? It should be shown at the top of the report window.

Hm, thats weird again... ;) This is how it looks for me (without my changes):

Yep, they match.

Actually I now notice the same thing in Angel's screenshot from the other issue thread. The AQ HUD and the map view show correct heading, but the sim HUD is 90° off. What the heck...? Weird is right!

Well this turned out to be pretty mundane.... I had committed the wrong image, of course. Funny no one mentioned it before, including everyone trying the PX4 version. :)

I assume this fixes it?

Thanks again Heiko!
