我正在为Android开发一个计算机视觉应用程序.这项工作涉及尽可能快地获取相机帧,所以我试图使用"android_native_app_glue"和"libnative_camera"直接在c ++中构建一个Android应用程序来获取相机帧.这似乎是不相容的.

我测试了2个选项.

1. 我尝试在Android NDK示例"NativeActivity"上使用OpenCV,只需进行一些必要的更改(将示例转换为c ++,修改android.mk和application.mk并包括使用名称空间和包含)它会出现以下错误:

sharedLibrary:libnative-activity.so C:/Development/android-opencv-wsp/samples/native-activity/obj/local/armeabi-v7a/objs/native-activity/main.o:在函数~Mat': C:\Development\android-opencv-wsp\samples\native-activity/../../OpenCV-2.3.1/share/OpenCV/../../include/opencv2/core/mat.hpp:297: undefined reference tocv :: fastFree中(void*)' 等等

1. 我尝试导入必要的库以在OpenCV2.3.1教程3示例上进行本机活动.我只是修改了Android.mk并添加了:

LOCAL_STATIC_LIBRARIES:= android_native_app_glue

立即,当我添加此行时,我收到以下错误:SharedLibrary:libnative_sample.so C:/ Development/android-opencv -wsp/samples/tutorial-3-native/obj/local/armeabi-v7a/objs/native_sample/jni_part.o:在函数~Mat': C:\Development\android-opencv-wsp\samples\tutorial-3-native/../../OpenCV-2.3.1/share/OpenCV/../../include/opencv2/core/mat.hpp:297: undefined reference tocv :: fastFree(void*)'等等......

请问,是否有人使用openCV2.3.1和libnative_camera测试纯粹的原生活动以获取相机帧？

提前致谢.
