// 运行程序: Ctrl + F5 或调试 >“开始执行(不调试)”菜单
// 调试程序: F5 或调试 >“开始调试”菜单
// 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
2 unity 调用dll
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.Runtime.InteropServices; //111111111111111111111111
public class OpenCamera : MonoBehaviour {
[DllImport("OpencvTest")]
static extern int addnum();
[DllImport("OpencvTest")]
static extern void opencaera();
int c = 0;
// Use this for initialization
void Start () {
// showing ();
c = addnum();
print (c);
//print(addnum());
opencaera();
}
// Update is called once per frame
void Update () {
}
}
运行结果
opencv里面控制键盘的输入在这儿也可以
