Projekt przejściowy do projektu Magisterskiego. Android, LibGDX, OpenCV, Camera, SurfaceView, stitching, panorama, sphere, gyroscope

About this panorama application:

This application is a study project

Features:

• 2D/3D user interface
• ability to taking photos and stitchung them to panorama
• ability to view pictures in gallery

This android project uses:

• OpenCV library
• LibGDX library
• ButterKnife

How to use app:

• The pictures will be taken ONLY when you are pointing in a centre of every rectangle AND if you dont shake camera too mach

• High quality: highest your divice provide (dont stitch more than 4 pictures)
• Low quality: pictures in HD (around 720p)
• Lowest quality: lowest provided by device (fast for testing)

Required:

• opencv-3.3.1-android-sdk
• android-ndk-r15c 64bit

How to change camera angle

Hi i wanted to change the focal length of the camera to capture 12 images instead of 8. I'm not able to do this can u please help me where should i modify the code

TEMPLATE_Android.mk is missing a entry

Hi,
the file Panorama360/android/src/main/jni/TEMPLATE_Android.mk is missing an entry which includes the opencv library.
The line
LOCAL_LDLIBS += -llog -L$(SYSROOT)/usr/lib
should read
LOCAL_LDLIBS += -llog -L$(SYSROOT)/usr/lib -lopencv
at least that's when it compiled for me.

Thanks for sharing your work.

if i change from lanscape to potrait in MainActivity then green dot for capture photo not able to focus("empty.png") how can i achieve potrait mode ? what changes require in sense of code?

Hi I'm capturing horizontal images only and when image stitching is completed 1 image frame getting misplaced please help

how to get OpenCV-android-sdk

OPENCVROOT:= C:\Users\Adam\Desktop\acodexm\Android\Study\OpenCV-android-sdk

Doc: suggest adding these steps for Android Studio

Here are some steps I needed to perform in getting the app to compile in Android Studio; not all of them are obvious; documenting them might save others some time.

1. Download old Android ndk r15c
2. Add to local.properties: ndk.dir=c:\\android\\sdk\\ndk\\android-ndk-r15c
3. Desktop module build.gradle, line 32 change ".classesDir" to ".classesDirs"
4. Download OpenCV 3.3.1 https://github.com/opencv/opencv/archive/3.3.1.zip and extract it into the top directory of the project
5. Copy android/src/main/jni/TEMPLATE_Android.mk to Android.mk
6. In Android.mk set OPENCVROOT var to the OpenCV SDK 3.3.1 downloaded above (e.g. C:/Projects/Android/Panorama360/OpenCV-android-sdk)
