Camera Mirror

[BobW55]

My image shows a correct North (top) and South (bottom) Orientation, but the east west is reverse. West is on the right side of the image and should be on the left.
If I use the flip Vertical, it corrects the N, E, S W orientation but the image is mirrored.
Is there a setting to correct this?

[EricClaeys]

@Alex-developer Alex, I know you were (or did?) reverse the compass images.

@BobW55, when did you do your "git clone" ?

[BobW55]

Towards the end of January this year

[EricClaeys]

@BobW55 Please grab the newest release. Alex changed reversed the images 5 days ago. When looking up, facing south, east is on the left.

[BobW55]

Do a new git clone?

[BobW55]

My North (Up) and South (Down ) are correct.
East and West are reversed. WIll update in the AM.

[EricClaeys]

Yes, a new "git clone --branch dev ..."

[BobW55]

So I dont screw it up.
cd
git clone --recursive https://github.com/thomasjacquin/allsky.git

[EricClaeys]

For the dev version you need to add --branch dev.
Ditto for the zAllsky Website.

Eric

[BobW55]

git clone --branch dev https://github.com/thomasjacquin/allsky.git

fatal: destination path 'allsky' already exists and is not an empty directory.

Do I need to delete something first?

[BobW55]

Never mind... figured it out.

[BobW55]

keep getting this error

Using 'dev' branch.

*** ERROR:

You need to install and set one before Allsky installation can run.

It will take a moment for the locale(s) to be installed.

When that is completed, rerun the Allsky installation.

I have run all the options for local

[EricClaeys]

@BobW55 I fixed this. You can either do a new git clone, or grab the install.sh script.

[BobW55]

[BobW55]

Ok is running the install now. But DID NOT detect my older version that was renamed allsky.OLD as prompted in the instructions.
Glad I wrote down all my settings.

[EricClaeys]

@BobW55 The prior version of Allsky needs to be named allsky-OLD with a minus sign, not a period. The installation script should have brought up a window that started with No prior version of Allsky found` and mentioned the correct name to use. You then had the option to rename the prior version to the correct one.

Did that not happen? If not, so you remember exactly how you ran the installation? And it was after downloading the "dev" branch, correct?

[BobW55]

Yes I renamed it .OLD
When I changed it to -OLD things ran.
Everything running but image is still incorrect.

[BobW55]

I regret to inform you the image is still messed up
West is on the Right East is on the left. The image is NOT mirrored
If I flip the image Horizontal (should have been vertical) the image is now correct but mirrored.

[EricClaeys]

@BobW55,
Bob, the compass images assume north is up in your captured image, and south is down. In that case, when looking South, East is on the left, so the compass image is correct.
The camera handles flipping, so it's done BEFORE the overlay is added.
In your images, is South at the bottom or top?

@Alex-developer,
Alex, do you think we need to distribute separate compass images for people that have South up?

[BobW55]

Its East and West that are wrong

[BobW55]

Un flipped.... North is at the Top, South at the bottom East is on the Left and West on the Right.
Flipped Horizontal, North is at the top, South at the bottom, East is at the right, West at the left but the imaged is mirrored.

[BobW55]

Even the compass image is flipped when Horizontal is selected.

[BobW55]

Un flipped.... North is at the Top, South at the bottom East is on the Left and West on the Right.
Flipped Horizontal, North is at the top, South at the bottom, East is at the right, West at the left but the imaged is mirrored.

[EricClaeys]

Instead of rotating and flipping, you can also just turn the camera...

I assume from where the Sun is in the picture below at South is at the bottom, so the compass is correct?

[BobW55]

No the comapass is incorrect. East is on the right side of the picture West is on the left. But objects are mirrored
On the bottom left is a telephone pole with a transformer on it. The transformer sould be on the left side of the pole not the right.

[EricClaeys]

have you tried not flipping but rotating the image? Or some combination of the two?
I assume the two poles around the 9:00 position should be to the right of the telephone pole?

[BobW55]

The camera is properly rotated
The two antennas you see are reversed but the tower they are on are on the west side of my house. there is also a small anemometer just at the bottom of the darker antenna, it should be on the right side of the tower.
I can post some normal pictures from my phone taken from the vantage point of the allsky then you will be able to see the issue.
I guess is depends on point of view.
if I lay on my back with my feet pointing north. Things on my right would be East, and on my left West. Straight ahead North and I waould have to tilt my head back to see South.
The opposite if I point my Feet south

[BobW55]

This is shot with my cell phone at the same location as the all sky camera looking West

[BobW55]

Maybe this will help. I understand that it may just be that East and West will be reversed.
Pic #1 no flip. Pic #2 Flip Horizontal Pic #3 Flip Vertical Pic #4 flip BOTH

[pablo-blake]

Hi Bob,

Are you indicating there is an issue with pic#1 ? I think it looks OK.
If your standing outside facing South and you look up at zenith, East is to your left and West to your right.

Are you describing some other issue with pic#1 ?

[BobW55]

But Im not facing South, I am facing North. East is to my right and West is to my left.
If I flip the image like Pic# 3 I can turn the camera and have the correct orientation. but now the imaged is mirrored.
I think I just have to give in to the fact that everything is set up for a view facing south not north

[EricClaeys]

@BobW55, a camera that faces straight up only faces up, not north or south. The only thing you can really change is which direction north appears in the image, and that's done by rotating the camera or the image.

My observatory camera is rotated so north is at the bottom of the image and west is on the left, only because that's what I see when I walk out my door, so it feels "natural" to me.

The current compass images will be wrong for me, and you too (?), so I will ask @Alex-developer to create an additional set.

Eric

[BobW55]

It is all good. A normal person views North as up on a map and most photos unless otherwise marked. When I look at an all sky image, I know the closer to the center of the image, the closer to Zenith. But I also expect North to be toward the top of the image, South at the Bottom, West on the Left And East on the right. Tried my camera on 4 different programs and they all use North Top, South Bottom East LEFT and West RIGHT.
So the compass roses in the overlay are CORRECT.
I just need my brain tweeked...LOL

[EricClaeys]

@BobW55 I definitely agree people expect North to be up and West to be on the left. Allsky doesn't impose anything regarding directions. I think part of the difficulty is that when holding a "normal" camera, you expect "up" in the image to be the top of the camera, and that's true as you tilt the camera up, but when pointing directly overhead, there is no "up", just "down". Now add in a 180-degree view pointing straight up and my head hurts thinking about it.

[BobW55]

I think that was my problem...... Over thinking it.
Could use a YELLOW compass rose though.

[bikeDiavm]

Based on your description, it sounds like you need to rotate the image by 180 degrees in order to correct the east-west orientation. Flipping the image vertically will correct the N, E, S, W orientation, but as you mentioned, it will also mirror the image.

Most image editing software should have a rotate tool that will allow you to rotate the image by a specific number of degrees. You can use this tool to rotate your image by 180 degrees, which should correct the east-west orientation without mirroring the image.

If you're not sure how to use the rotate tool in your particular image editing software, I would recommend checking the software's documentation or doing a quick search online for a tutorial specific to your software.
