I've noticed that these things are becoming popular,
And I thought why not make one for my Android head unit?
After doing some research in Computer Vision and hacking my car's android, I'm happy to announce that it works
You can see a live demo in my youtube channel - https://www.youtube.com/watch?v=dzpn0ROKkX8
The solution is software only - it uses complex computer vision algorithm (optimized the hell of it for embedded devices) to draw a top view of the surroundings of the car.
It translates rear camera view:

into top camera view (with memory of previous seen space - its a buch of mathematics that does that inside):
Hope soon to release the app

Existing solutions use 4 cameras with an extra unit that stitches them together or using odometry.
I'm aiming for a software-only solution, using only Android MCU and reverse cam that we already have.
Doing some research on my PC, I've managed to achieve some progress.
You can watch the video in my youtube channel
Managed to open reverse cam with OpenCamera app and even record a video.
For that killing SofiaUIServer process on my MCU was needed coz its responsible for turning on the camera as soon as you hit reverse.
That means that I can write a pure android app that does the bird view (hopefully performance won't be an issue).
Now it's only a matter of time (and will) until I finish that little project on Android.
What do you guys think, will there be a demand for such a thing?

I am interested in this project.
I have both rear and front cameras. The front camera can be opened only with F-CAM app which does not do recording. It would be nice to have both cameras showing on screen and recording. My system is mtcd based and I am not sure if your app would work.
Update:
I have a working demo in my car which can be seen in this video - https://www.youtube.com/watch?v=jlUI662VCA8

wow, very detail!
HI,
could this work on an Atoto head unit, would you mind to share the app?
Thanks
Frank
Wow, amazing work! Can't wait for the release.
Good luck!

You don't need working drivers for that video - it's Liverpool - they always play in slow motion anyway so no problems with camera lag

Nice
Interestingly that endgadget article has a post that this phone does not actually run Windows Mobile... but some sort of rip-off.
Other sites that sell the device don't state WM6 (or any version) on their features list.
Does M$ charge alot for putting WM on a device? If so that could be one reason for the low price.
Plus it only has a 30 day warranty, I believe the tilt has a 1 year(?)

Uses "some sort of Windows Mobile operating system". The real one is already a buggy mess, go figure that one...LOL
I bet it will perform better than the Kaiser, and I'm not kidding (sadly).
It will probably perform better than the Kaiser because it is using a basic OS that is more like a calculator than a Windows Mobile.
So, it probably boots up in 5 seconds, switches apps in a fraction.
But it also probably doesn't have TouchFlo, PIE, or many of the other features that make the Kaiser/Tilt nice.
It is like any of the other numerous phones out there on the market (like from Verizon) that have a slide out keyboard with a proprietary OS.
This of course is assuming the statements above about it not being WM6 are true. If it indeed runs WM6 then I am sure the performance will be equivalent to the Kaiser.
Please, vote for my idea if you like it on Google Product ideas.
Or if you are an Android developer you can "just make it"

As you know, since last week Youtube makes it easier to upload and view 3D videos. More info:
http://youtube-global.blogspot.com/2009/07/now-in-3d-join-experiment-with-us.html
"3D video/photo shooting app for Android. By using 2 Android devices the app should sync them by Bluetooth, so they can start, stop, pause simultaneously. After shooting the video this app should combine as red/green and share via Youtube/Picasa."
That isn't practical since you would need two devices.
I am sure that soon we will see phones with 2 cameras on the back that would be able to shoot directly in 3D, but until then I can't think of a more practical way for videos. Android should be the best environment for this.
For photos you are right, it is possible to do it with just a single camera.
nice idea, but highliy impracticle. 3D video shooting has been around for decades and it's still just a WOW-factro technology. Even with all the TVs that are going to be released with 3D capabilities, you still need to wear those goofy glasses in order to see things right.
Just because YouTube is catering to 3D video technology does not mean that we will see cellhpones with two cameras on them.
with this out
3d cameras on cell phones shouldn't be too far..

You don't need any kind of "special TV" to watch 3D images. The "goofy" glasses are available and are cheap enough (1.5-15$) to have them near your LCD TV or Monitor.
The world is moving much faster to the 3D technology. A recent example is Ice Age 3.
Back in year 2000, when I installed probably the first complete CarPC in Europe ( http://www.carstereo.com/installs/photo_gallery_album.cfm?home=yes&photoid=18833&galleryid=609 ) I heard very similar opinions that "it is not practical", and etc. Now it is something normal, available and you don't have to DIY.
When the TV came out, people called it "impractical" and a waste of time and that no one would sit on a chair to bother watching it.
When the PC came out, it was also called impractical and that nobody would want to use it.
When the G1 came out, I looked at it and thought to myself "damn that is one ugly phone, no one would ever want to use that." And my friends agreed with me.
Look at where we are now
Samsung released Video Call a 3G Video Call App for Mango WP7 Phones.
I couldn't find it in the Samsung Zone...
But it poped up in the Search when i clicked "more from SAMSUNG ELECTRONICS Co., Ltd." on the Details View from other Samsung Apps.
I can not test it right now, because I'm aboard for 2 weeks...
Maybe it can use also the Backcamera?? *hope*

Front facing camera is a requirement. However, how to make video calls without a ffcam?
I used Video Call on my old HTC Blackstone a lot, most of the the time i switched to the rear camera (to show something) or disabled the front one..
At least you can see the receiving video... i admit there are big drawbacks for the
most, but the app would not be complete useless for people without front camera.
And you can install the app without front facing camera...

I'm not agree with you, what video you will receive if your party have a handset without ffcam too?
Actually, in general it means - it's time to update your Samsung phone
P.S. BTW, I've attached zipped xap; may be our whitehats will find something interesting inside (and possible, reflect to source code and make it works with backcam)
P.P.S. Good news: app is non-obfuscated and can be easy reflected to the source code. On the first sight, it has a lot interesting stuff inside

stand in front of a mirror.....
I have recently bought Samsung focus S but i am not able to get the Video call app from samsung marketplace. It says application not available for my device. This phone has front facing camera then why i am not able to install the video call app. Can anyone post the latest version XAP which can be installed by Tom XAP installer.
Thanks a lot.
I think it is because of Operator
It is disabled somewhere in registry.
---------- Post added at 05:34 PM ---------- Previous post was at 04:52 PM ----------
Who was able to install it, tell us please your Region+Language settings, your operator and branding
Why dont you just use skype which as I remember allows videocalls using your back camera?
The stock app on my S10e does not appear to have a white balance option for the front facing camera, and it doesn't automatically choose it correctly. GCam always creates superior results.
I can't imagine Samsung app devs would let their app be so terrible with selfies. Does anyone else have the same experience? Is there a feedback channel we can tell them?
Like I said on another thread why do you guys feel the need to have and use a front facing camera to take pics of yourself. I'm trying to understand is it a narsasiscic thing going on in this day and age or what?do people fancy themselves that much? not talking about you op or anyome here in particular so no disrespect intended. Just want to understand this need for front facing cameras. I love the s10 plus but the ugly 2 cameras on the front are stopping me from enjoying.and I'm not in love with myself to take selfies and admire my self all day.so the front camera ruins the phone for me a bit

People have always been taking pictures of others, and some have noticed that the cameraman has been missing for centuries.
Now we have a tool in our pockets to take a picture of everyone at once, in an instant. The S10 has a wider lens for even more people.
Every game night, I take a selfie with everyone using the GCam app in portrait mode. When I have a special moment with my wife, its easy to get a photo of us together. It's kind of ridiculous looking back at photos from years ago to know I was a participant, but no where to be seen, not a single photo of me interacting with others.
I took advantage of a sale at Office Depot for canvas prints, and made a collage of a year's worth of selfies:

A picture is worth a thousand words.
To illustrate the problem, below are two photos of my cat. The first was taken using the native Samsung camera app. The second using a port of Gcam.

Do you see the problem? Pictures taken with the Samsung camera app produce this "smudging" effect, making it look almost like a painting, or a cartoon.
This problem is very prevalent once you start using the camera a lot, taking lots of photos. Usually happens when the scene includes a lot of small details that need to be captured, like people's faces, or a textured intricate pattern.
Instead of accurately representing those details, the camera produces this smudged cartoony effect more often than not.
Since using the ported Gcam app on the same phone, same hardware, produces far superior results, it is reasonable to conclude that this is a Samsung software issue, and that the post-processing algorithm is not up to par.
My question being, is this a known issue? Is something being done about it? Is there a solution other than using 3rd party apps like the Gcam port used in my examples?
I'd much rather use the native camera app provided by Samsung, but as it stands currently it's just really not up to the challenge.
Will appreciate any feedback, thanks!

No.
P.S. What gcam port do you use exactly? Could you please link?
Do you see gcam improvement also in video comparing to stock camera app, filmic Pro and open camera?
Wow, that's so disappointing to hear!
One of the reasons I bought this phone was for the camera upgrade, thinking it would be decent.
Can't believe that it's this flawed for a device that came out in 2020.

I just used the one that was advertised on this forum: https://www.cyanogenmods.org/galaxy-a71-google-camera-apk-download/
Seems to work well for the most part. I mainly tested it with taking photos. Video quality seems to be about the same as the stock Samsung camera app, but I haven't tested it extensively to be fair.
I have noticed this smudging in other apps such as snapchat too, it's even worse there.
