1).首先下载opencv for mac安装源文件,http://opencv.org/downloads.html,解压缩 2).安装brew:终端输入: ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)" 更新Homebrew,Terminal中输入:brew selfupdate 3).安装cmake:brew install cmake 4). 进入存放解压后的opencv文件夹,新建一个空的文件夹...

在这里,我们主要是调用OpenCV android SDK中的API来实现打开相机的功能。 一、知识准备: 1.了解Android工程如何运行在设备上 2.了解C/C++编译过程,能够读懂makefile 二、实现流程: 1.打开Eclipse,新建一个空白的Android工程: 项目名称为OpenCV_Test: 2.为新建工程引入OpenCV Library - 3.1.0库工程: ...
