vs配置opencv环境 opencv绘制海康相机

首先我们打开vs
创建一个控制台应用





去上一层目录 然后选择×64 debug 讲海康相机以及opencv的dll文件复制进去

分别在opencv的这个目录下

以下是调用的代码

// 入门使用技巧: 
//   1. 使用解决方案资源管理器窗口添加/管理文件
//   2. 使用团队资源管理器窗口连接到源代码管理
//   3. 使用输出窗口查看生成输出和其他消息
//   4. 使用错误列表窗口查看错误
//   5. 转到“项目”>“添加新项”以创建新的代码文件，或转到“项目”>“添加现有项”以将现有代码文件添加到项目
//   6. 将来，若要再次打开此项目，请转到“文件”>“打开”>“项目”并选择 .sln 文件
