Unity双目相机
天人合一peng 人气:01.vs中生成dll
对应的生成dll的cpp如下
#include<opencv2/opencv.hpp> #include "opencv2/core/core.hpp" #include "opencv2/imgproc/imgproc.hpp" using namespace cv; #define EXPORT_API __declspec(dllexport) VideoCapture my_camera; int width = 640; int height = 480; extern "C" bool EXPORT_API openCamera() { bool my_open = false; while (!my_camera.isOpened()) { std::cout << "Cannot open the camera!" << std::endl; my_camera.open(0);//一个接口能同时打开两个摄像头 } my_camera.set(CV_CAP_PROP_FRAME_WIDTH, width*2); my_camera.set(CV_CAP_PROP_FRAME_HEIGHT, height); if (my_camera.isOpened()) { my_open = true; } return my_open; } extern "C" void EXPORT_API recieveFrame(uchar* texturePtr) { Mat my_frameBGR; Mat my_frameRBG; my_camera >> my_frameBGR; if (my_frameBGR.data) { cvtColor(my_frameBGR, my_frameRBG, CV_BGR2RGB); memcpy(texturePtr, my_frameRBG.data, my_frameRBG.cols*my_frameRBG.rows*my_frameRBG.channels()*sizeof(uchar)); } } extern "C" void EXPORT_API closeCamera() { if (my_camera.isOpened()) { my_camera.release(); } }
2.unity中justatry脚本
using UnityEngine; using System.Collections; using System.Collections.Generic; using System; using System.Runtime.InteropServices;用 c++中 dll 文件需要引入 public class justatry : MonoBehaviour { [DllImport("_dectecting")] public static extern bool openCamera(); [DllImport("_dectecting")] public static extern bool recieveFrame(byte[] imageData); [DllImport("_dectecting")] public static extern bool closeCamera(); public bool IsOpen = false; public byte[] imageData; public Texture2D tex; public int Width = 640; public int Length = 480; // Use this for initialization void Start () { IsOpen = openCamera(); if(IsOpen) { imageData = new byte[Length * Width * 3*2]; tex = new Texture2D(Width*2, Length, TextureFormat.RGB24, false); } } // Update is called once per frame void Update () { if (IsOpen) { recieveFrame(imageData); tex.LoadRawTextureData(imageData); tex.Apply(); GetComponent<Renderer>().material.mainTexture = tex; } } void CloseCamera() { if (IsOpen) { closeCamera(); } } public void OnApplicatoinQuit() { closeCamera(); } } using System.Runtime.InteropServices;用 c++中 dll 文件需要引入 public class justatry : MonoBehaviour { [DllImport("_dectecting")] public static extern bool openCamera(); [DllImport("_dectecting")] public static extern bool recieveFrame(byte[] imageData); [DllImport("_dectecting")] public static extern bool closeCamera(); public bool IsOpen = false; public byte[] imageData; public Texture2D tex; public int Width = 640; public int Length = 480; // Use this for initialization void Start () { IsOpen = openCamera(); if(IsOpen) { imageData = new byte[Length * Width * 3*2]; tex = new Texture2D(Width*2, Length, TextureFormat.RGB24, false); } } // Update is called once per frame void Update () { if (IsOpen) { recieveFrame(imageData); tex.LoadRawTextureData(imageData); tex.Apply(); GetComponent<Renderer>().material.mainTexture = tex; } } void CloseCamera() { if (IsOpen) { closeCamera(); } } public void OnApplicatoinQuit() { closeCamera(); } }
注意,脚本要挂在plane上
3.在unity中调试
dll的输出目录是 unity项目工程名\Assets\Plugins
D:\Michael Wang\SC\2018\1\openDoublecamera\UnityTry\Assets\Plugins
4.在vs中调试
4.1 把unity的工程生成对应的exe
这是生成的unity exe对应的生成目录
对应的目录如
D:\Michael Wang\SC\2018\1\openDoublecamera\UnityTry\test.exe
4.2 在vs项目的属性中做如下设置
命令后用上面的路径,注意是放在命令里不是命令参数里
在对应的unity exe目录中找到 unity工程名_Data下Plugins的目录是
D:\Michael Wang\SC\2018\1\openDoublecamera\UnityTry\test_Data\Plugins
4.3 在VS工程的属性中的输出目录设置为上面的目录
做完以上设置就直接可以在VS下调试了。
5.注意vs和unity的平台x86/x64要对应
5.1 vs x86/x64
5.2 unity
如果按以上设置还是不对,提示找不到dll,则把dll的输出放在与Plugins或Assets文件夹同一级尝试。
如果你已经把dll放在这里了,还是显示找不到,则一定是你用vs生成dll的库没有在环境变量里,然后unity里面调用时找不到vs生成dll所依赖的一些库。可以把一些你知道的库直接放在vs生成的dll一起,全放在unity工程里,应该就好了。
