No-Camera OpenCV

Sample application that shows OpenCV running on both a physical device RICOH THETA V and an Android Video Device. You can develop a plug-in on the emulator and then have it run on a physical device camera with only minor modifications.

Based on original work by roohii_3 with modifications by https://github.com/iamagod (kasper on theta360.guide)

Important Note on App Permissions

You must enable storage permissions in the settings. If you have using a physical device RICOH THETA, you can use Vysor to go into Settings and enable storage permissions.

Usage in emulator

• Use your mouse to press Shutter button. It will load an image into /sdcard/DCIM/100RICOH/
• Use your mouse to press the Process button. It will display an image processed with OpenCV to the emulator screen.

Using real camera

• Press the shutter button to take a picture
• After 4 seconds, press the Wi-Fi button to process the picture

You can see the processed image in Vysor. This demo does not save the processed image to disk.

The no-camera-template shows how to save the processed file to disk.

Build

• JRE 1.8.0
• Android Studio 3.3.2
• Gradle 4.10.1
• OpenCV 3.4.5
• in gradle.build (app) specify sourceCompatibility and targetCompatibility as 1.8 due to use of lambda

In Android.mk set your include path.

To see the Android.mk file, go to the "Project Files" view of Android Studio. The default view is "Android". You need to access Project Files from the drop-down menu.

Edit the path in the screenshot below to match the path of your local OpenCV source code (which is part of this repo).
