OpenCV android c++ full resolution camera frame capture

asked 2013-12-11 21:30:38 -0500

I use smartphone camera for object detection. And I use JavaCameraView for frame capture.

Now I can find and detect some objects that I need on Preview using native c++ and Opencv;

TASK: 1. I need make automaticaly full resolution photo in case, if object found on screen; 2. Than convert big photo to Mat object, to make some operations with it, using opencv and native c++.

Ask for your help with some Algorithm to find out solutions that let to do this? Thank you.

What device you are using? and what resolution do you need? Is 720p is good enough? From my experience, I know that galaxy s4 can use full HD resolution(1920x1080) in camera recording mode and just show camera mode but in galaxy s3 the full HD resolution is only in recording mode, so if you want to perform image processing on 1080p on galaxy s3 you need first to record video and then decode the video.
