Question

我试图按照these instructions获取OpenCV来编译我的MAC MINI，但在第6步失败了：

../ opencv_cmake.sh模拟器../ OpenCV-2.1.0

我遇到了这些错误，我无法理解它。有线索吗？

OpenCV Install Prefix = /Users/haoest/Development/iphone_opencv_test/build_simulator/../opencv_simulator

Answer 2

您确实意识到Niwa有一个预编译版本（通过github链接或在他的网站http://niw.at/articles/2009/03/14/using-opencv-on-iphone/en上），您可以在其中打开Xcode opencv_test.proj文件。它包含一个示例项目，可以帮助您入门，您可以从那里开始构建。它适用于iPhone设备和模拟器。

Answer 3

OpenCV现在可用作iOS的框架。只需拖放到您的项目中即可。它也支持视频捕获。请参阅文章并获取示例项目here。
