Problem while installing on Android

[murtaza98]

Hey,
I tested this on my laptop using its webcam and it worked fine.

However, when I am installing it on my Android phone, I am getting some errors like this.
09-26 23:01:08.858 25404 25427 E Unity : DllNotFoundException: OpenCvSharpExtern 09-26 23:01:08.858 25404 25427 E Unity : at (wrapper managed-to-native) OpenCvSharp.NativeMethods.core_Mat_sizeof() 09-26 23:01:08.858 25404 25427 E Unity : at OpenCvSharp.NativeMethods.TryPInvoke () [0x0000e] in <1c4180998434408a87e8d3a3d5f215e6>:0 09-26 23:01:08.858 25404 25427 E Unity : Rethrow as OpenCvSharpException: OpenCvSharpExtern 09-26 23:01:08.858 25404 25427 E Unity : *** An exception has occurred because of P/Invoke. *** 09-26 23:01:08.858 25404 25427 E Unity : Please check the following: 09-26 23:01:08.858 25404 25427 E Unity : (1) OpenCV's DLL files exist in the same directory as the executable file. 09-26 23:01:08.858 25404 25427 E Unity : (2) Visual C++ Redistributable Package has been installed. 09-26 23:01:08.858 25404 25427 E Unity : (3) The target platform(x86/x64) of OpenCV's DLL files and OpenCvSharp is the same as your project's.

Any suggestions would be appreciated. Thank you in advance.

Hi,
The OpenCvSharp used in this project works only on Windows?

https://github.com/digital-standard/ThreeDPoseUnityForiOS
This code can be run on iOS using "OpenCV for Unity" (paid).
I haven't tried it on Android yet, but I think it will work on Android.

This is a video when running on iOS.

Hello. Thanks for the response.
I understand that OpenCvSharp and the OpenCV dll files used in this project are meant to be run on a Windows Platform.

BTW, if u won't mind, I would like to get your advice and suggestion on the project that I am developing.
Basically, I want to develop an application which uses pose-estimation and I want to render some 3d Models on that pose and all this needs to happen on an Android.
So, if u could give me some suggestion about the high level approach that i should follow, it would be really appreciated.

Android is not so detailed, so there isn't much advice.
If you use pose estimation using Unity, I think it's "OpenCV for Unity" or Unity's "Barracuda" or "TensorFlow".
(I think there are other things you can use.)

Barracuda
https://github.com/Unity-Technologies/ml-agents/blob/master/UnitySDK/Assets/ML-Agents/Plugins/Barracuda.Core/Barracuda.md

This video uses Barracuda.
It works fast on a PC but very slow on iOS.
I think it works on Android, but I don't know the speed.

I haven't used Unity + TensorFlow so I don't know.

Everything that uses my code needs to be changed.

How can I deploy it to an android phone?
