OpenCv on moto droid

[maxi]

Im trying to use the pre built OpenCV packages on Android using the
Moto Droid. It compiles and loads without errors
However the camera seems to load up(it makes the clicking noise) but
without any display. The menu works but there is no display on the
screen apart from the top status bar and title bar. On killing the
application the Sorry dialog box appears with the not responding
message.
Any idea what seems to be wrong.
Should i try building the CV sources with the NDK?

Hi,

Could you provide us more details?

Particularly following details will be very helpful:
1) What sample are you trying? If it is one of samples provided with
package then we need only name of sample. If it is your own sample
then please shortly describe your scenario.
2) Exact CPU model of your device.
3) Android version number.
4) Output of `adb logcat` for running sample.

Thanks,
Andrey

None of the samples provided in the openCV 2.3.1 tar.bz seem to work

Model number: Droid
Android Version: 2.2.2
Kernal Version 2.6.32.9-g68eeef5 android-build@apa26 #1

This is the dump of the adb logcat

What do you think is wrong
Let me know if you require any more details

It seems that your camera returns image in yuv422i-yuyv format which
is not default for Android platform. Currently OpenCV supports only
yuv420i raw format.

Try to add following line
params.setPreviewFormat(ImageFormat.NV21);

before the line
mCamera.setParameters(params);

in SampleViewBase.java

It might fix samples with Android camera (tutorial-0-androidcamera and
tutorial-1-addopencv).
Please post a note if this fix works for you.

But this parameter for OpenCV native camera is not accessible. To work
with native camera you need to retrieve raw frame instead of rgba or
gray-scale and make format conversion yourself.

Hmm, I made the changes but it didnt work
Is there any other way to change the video format?

this is the logcat

Probably another constant will be helpful. Try to use
ImageFormat.YV12 and ImageFormat.NV16

Please also check whether gray preview works or not. It may happens
that only RGBA is broken.

If this also fails then custom YUV422 to RGBA converter seems to be
the only option.

Hi Akshay,

The bug in camera initialization was found.
See https://code.ros.org/trac/opencv/ticket/1244

To fix Java camera samples you need to add the following lines
try {
mCamera.setPreviewDisplay(null);
} catch (IOException e) {
Log.e(TAG, "mCamera.setPreviewDisplay fails: " + e);
}

before the line
mCamera.startPreview();

in SampleViewBase.java.

Fix for native camera probably will be included into beta2 release.

Hi Andrey,

I tried the code snippet below, Does not solve the problem
Nor does the exception get logged in adb logcat

I tried changing the formats, YUY2 and N21 run without any camera
display
the other formats cause an exception on launching

Hi Andrey

I added this line
mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

and insted of passing null i pass the holder in setPreviewDisplay

setPreviewDisplay(_holder);

It works for about 2-3 s before terminating with an error
I can provide the logcat if you want

Hi,

It's no good that previous fix does not work for you. After that fix
samples work on all Android 2.2.2 devices we have access to.
Please provide logcat output, it might be helpful.

Regarding your problem:
1) Camera is successfully opened and initialized, but doesn't start
previewing.
2) Image format returned by your camera is yuv420sp and it is the
expected format.
3) The code
mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
setPreviewDisplay(_holder);
puts camera to the 'overlay' mode. It is standard technique to
directly connect camera and surface. This mode is very performant
because it works without any involvement of JVM. But it has it's own
drawbacks that makes it unusable for many of OpenCV demos. The corner
case is that we want to modify image before showing it. So we have
implemented native camera wrapper which gives us the same speed as
overlay but allows to modify the image before visualization.

The only idea that I currently have about crash in overlay mode is a
PreviewCallback timeout. Please try to set camera resolution to the
lowest possible (176x144) value. Will it terminate in this case?

Now the logcat for the following bit of code
mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

try {
mCamera.setPreviewDisplay(_holder);

} catch (IOException e) {
Log.e(TAG, "mCamera.setPreviewDisplay fails: " + e);
}

mCamera.startPreview();
}


The camera preview does start but the application quits after a few
seconds

E/AndroidRuntime(15902): android.view.SurfaceHolder
$BadSurfaceTypeException: Surface type is SURFACE_TYPE_PUSH_BUFFERS

Have you tried other types of surface?

Another suggestion about first scenario (with null surface).
Please try to place setPreviewCallback after setPreviewDisplay (but
before startPreview). Will it work in this order?

I expect to see something like

D/Camera ( 5360): app passed NULL surface
W/CameraHal( 1030): No overlay set before start preview
D/CameraHal( 1030): deinitPvOverlay()
D/CameraHal( 1030): Trying to set overlay, but overlay is null!
D/TIOverlay( 1120): overlay_createOverlay:IN w=720 h=480 format=99

in the logcat output. But in your log CameraHal is quiet after "No
overlay set before start preview" message.

I'm having this same issue with my Droid X. Does anyone know if a
solution exists?

The problem is "non-trivial" ;-) due to device-dependence of OpenGL
versus Canvas for preview Callbacks... I suspect it might get added as
an option to use GL for preview. Problem stems from Motorola being
less entrenched outside of USA, this seems to be a bigger issue than
at first glance.

FWD from Andrey:

You have commented out the notify() call so processFrame is just never called.

Googled somewhere in the web:

Some smartphones don't care if they won't get a surface provided, e.g.
the Nexus One and the T-Mobile G1. On those you may start the preview
right away, without setting a preview surface. Nevertheless there are
Android smartphones that will not provide a video stream if no preview
surface was set. One of them is the Motorola Milestone. However you
may not provide the OpenGL surface as a preview surface to the camera.
This would cause conflicts, as both the camera and the OpenGL thread
would try to access this surface at the same time. Furthermore this
surface must be visible on the screen, otherwise the preview callback
will not be invoked, either.

The solution for this problem is to layer a OpenGL surface on top of
the preview surface. This way the preview surface is regarded to be
visible, even tough it is not. This method works on all Android
smartphones. The video stream is drawn on a surface that is not
visible to the user and additionally on a OpenGL texture.
Compatibility is more important, then avoiding this overhead. There is
no other way to circumvent this API design decision.

If this statement is correct then there is no efficient java solution
for Motorola phones. Probably we can overcome this problem for native
camera interface but this is not trivial and requires to dig deep into
Android sources.
