なんとなく実験 with SIProp開発記

実機にインストールしましたが、
マーカーをうまく認識してくれません。
何か方法がありますか？

• moge

mogeさん

注意点は、2点あります。

１，マーカーがよく使われる「Hiro」でありません。
日本Androidの会っぽく「JAG」としてあります。

２，G2(HT-03AやGDDフォン)では、未テストです。すみません。
余裕が出来たときに見てみますが、確か動いていた気がします・・・

• noritsuna
• 2009年06月23日 20:30

うまく動きました。
向きがあるんですね。
印刷したマーカーだとうまくいかず、
ディスプレイのマーカーだとうまくいきました。

Hi ,

Could you please tell me if I can use the code on Android SDK version 1.
5 or on SDK version 2.0.

When i tried running the code you have shared on SDk version 1.5 the cod
e crashed on the first call to the core ART at arToolkit = new ARToolkitD
rawer(camePara, patt, mRenderer);

I have imported both the projects that you have shared and ran it on G1
phone.

Thanks for the help.

I try to run the last version. Why it is just a black screen when I run
the program on G1 or emulator successfully? Is the program for using the
camera in G1 or just for using a web camera? Looking forward to your repl
y! Thank you.

Thanks noritsuna! I have run it successfully! However, the speed is stil

Hi, noritsuna!
I am trying to get NyArtoolkitAndroid running on 64-bit Win7 in Eclipse 3.51. I downloaded ...-2.0.1-forSDKr3.zip, imported the 2 projects to Eclipse, but when building I get this: [2010-01-14 19:34:46 - NyARToolkitAndroid]warning: Ignoring InnerClasses attribute for an anonymous inner class that doesn't come with an associated EnclosingMethod attribute. (This class was probably produced by a broken compiler.)

[2010-01-14 19:35:12 - NyARToolkitAndroid]Conversion to Dalvik format failed: Unable to execute dex: null

I want to know which operating system and Eclipse version You use?

• Henri

Alright I made new workspace and imported the projects and NyARToolKitAndroidActivity started :), but how can I can only use my webcam. How can I send video to a socket. I have a http serving webcam and I got Tom Gibara's HttpCamera working couple of days ago with webcam7 httpcamera.

• Henri
• 2010年01月15日 04:19

Hi

looking forward to get this running. When I'm running from eclipse, it depends on the core-files. I can only run the core-setup = black screen...

• Jesper Johansen
• 2010年01月17日 06:05

I have downloaded NyARToolkitAndroid-2.0.1-forSDKr3.zip and trying to make it work with Google API (platform 2.1, API level 7, SDK version 4).

I made a new project fro the WebcamBroadcaster and changed the strings.xml to use the SocketCamera. I verified that the connection to the broadcast is made when running in the emulator, but I don't get the picture (only shows the Loading picture on emulator screen).

Is there anything I can do to make it work or I have to use Android SDK 3 and SDK platform 1.5?

Thank you, noritsuna for all your work.

• Harrys
• 2010年01月20日 10:31

Update: I have now been able to get the example running by converting the socket camera to http camera, so currently I download a 320x240 jpg with http that has a marker drawn on it and the code finds the marker and draws that blue 3d model on it :). I tried it with 640x320 sized image, but somewhy there is a very big allocation made and something crashes: 01-20 15:09:29.003: ERROR/AndroidRuntime(214): Uncaught handler: thread Thread-9 exiting due to uncaught exception
01-20 15:09:29.011: ERROR/AndroidRuntime(214): java.lang.OutOfMemoryError

Jesper I reccommend you to look at LogCat and see maybe u get some exception also.

• Henri
• 2010年01月20日 23:47

Hi, Henri & Harrys

Sorry, The reply became slow.

WebCamera program is WebcamBroadcaster/WebcamBroadcaster.class .

Please run WebcamBroadcaster/WebcamBroadcaster.class and write your PC's IP address in values/strings.xml server_addr.
(with Java Media Framework.)

The parameter which adjusts the size of a Bitmap is

jp.android_group.artoolkit.ARToolkitDrawer
Line 72 :
options.inSampleSize = 4;

Bitmap is to 1/4.
Please adjusts this parameter or

jp.android_group.artoolkit.ARToolkitDrawer
Line 78 :
if(bitmap.getHeight() < 240) {

hi

i have a htc hero how i can get ur program to work on my phone

• robert
• 2010年01月21日 23:24

I thank you for the answers! But i still can't use WebCamBroadcaster. I think it's because I have windows 7 and JMF won't work on it. My capture device dont have RGBFormat, so I changed it to YUVFormat in WebcamBroadcaster, but then got another error: that said something like ".... jmvfw not in the library.path". I tried reinstalling JMF, but now it wont eaven detect my usb webcam. Im gonna try it on winXP virtual machine. Actually what I need is just drawing the 3D graphics on the video, I do not need marker detection. Do you know what would be the most simple way to do it?

• Henri
• 2010年01月22日 21:23

Hi, robert

Please try this APK.

Hi, Henri

> Actually what I need is just drawing the 3D graphics on the video, I do not need marker detection.

Sorry, I don't know.

• noritsuna
• 2010年01月22日 22:15

Well, it was a bit foolish of me to ask it that way :). I'll try to be more precise: I just want to draw a cube with OpenGL so that on the background there is the video from the camera. Like with marker detection, the cube is drawn on the video. I don't want to know the simplest way to do it. I want to know which class in NyARToolkitAndroid draws the OpenGL geometry on the bitmapped image?

• Henri
• 2010年01月22日 23:15

Hi, Henri

3D renderer is

jp.android_group.artoolkit.ARToolkitDrawer
&
jp.android_group.artoolkit.ModelRenderer

source files.

But this how to do is old version.
I am developing new version.(Android 2.x native version)

If you want it soon, please you google it.

• John
• 2010年02月26日 13:30

True John,

Probabily because of the camera calls written in Java may not be so optimal...Try NDK!

hi
I think I did all for test your source
->
1. installed the jmf and then copying jmvfw.dll to the jmf lib.
2. editing the xml to use the socket camera,
3. running the webcambroadcaster and it's working..

like someone above did

but I got black screen.....

In logcat
I got some error
ERROR/GLLogger(56): couldn't load library (Cannot find library)

ERROR/MemoryHeapBase(56): error opening /dev/pmem_gpu1: No such file or directory

ERROR/Camera(265)

How can I fix it ?

• sang
• 2010年03月03日 14:39

hi
I got small improvement in test.
after your activity open in emulator,
there are no errors in logcat.
also socket camera start well.
and I checked some message about
AR draw ...

but in emulator screen,
just only endless
"loading" message show
over and over

I am not sure this result I got is right
Should i add some code for camera
preview?

• sang
• 2010年03月04日 11:30

Hi,

I'm starting in programing Android, so I follow all tutorial instructions to run NyARToolkit in Android. But I've obtained some errors, and I don't know why. Let me explain what i'm doing:

- I downloaded Eclipse, Android SDK, ...
- I imported the last version of NyARToolkit for Android (NyARToolkitAndroid-1.0.1.20080522)
- And, without any change, I obtained two errors:
1.- "The project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object. Fix the build path then try building this project"
2.- "The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files"

Well, Why did I obtained errors? I didn't make any change. It supposed that must to run well ¿not?

Please, Can anyone help me?

Thx

Hi again. You were right, they answered me suggesting I would change 2 things in the original code:

in NyARToolkitAndroidActivity.java.

- private boolean mTranslucentBackground = true;
+ private boolean mTranslucentBackground = false;

in res/values/strings.xml.

- jp.androidgroup.nyartoolkit.hardware.HT03ACamera
+ jp.androidgroup.nyartoolkit.hardware.UVCCamera

I tried it and it runs very well now. Thanks for your advice.
