cvGetMat中无法识别或不支持的数组类型 [英] Unrecognized or unsupported array type in cvGetMat

问题描述

我在这里搜索了一下，但没有人似乎有同样的错误，我试图在树莓pi上创建一个颜色检测摄像机，我使用

https://github.com/robidouille/robidouille/tree/master/raspicam_cv

，但现在我有

  IplImage * image = raspiCamCvQueryFrame（capture）; 
 cv :: cvtColor（cv :: Mat（image），x，cv :: COLOR_BGR2HSV）; 
  

它会编译，但运行时会给出

函数cvGetMat中无法识别或不支持的数组类型

没有cv :: Mat（image）因为

从IplImage *类型的表达式初始化类型为cv :: InputArray的引用

解决方案

以下代码将显示窗口中的网络摄像头的提要，程序将终止当按下'q'时：（源）

  #includeopencv2 / highgui / highgui.hpp
 
 int main int argc，const char ** argv）{
 cv :: VideoCapture capture; 
 cv :: Mat image; 
 
 //除非你需要从多个设备获取图像，
 //使用'-1'将自动选择网络摄像头。 
 capture.open（-1）; 
 if（capture.isOpened（））{
 cv :: namedWindow（WebCam，cv :: WINDOW_AUTOSIZE）; 
 while（1）{
 capture.read（image）; 
 cv :: imshow（WebCam，image）; 
 int c = cv :: waitKey（10）; 
 if（（char）c =='q'）{
 break; 
} 
} 
} 
 
 capture.release（）; 
 
 return 0;我在Ubuntu 14.04上测试了这个代码，并编译成这样：    p> 
 
 
  $ clang ++ -o cvtest cvtest.cpp -lopencv_core -lopencv_highgui 
  
 
 
 
 
 
 
如果您想继续使用 IplImage 和C接口，那么我不能帮助你。
 
I searched around a bit on here but nobody seems to have the same error, I am trying to create a color detection camera on the raspberry pi, I used 

https://github.com/robidouille/robidouille/tree/master/raspicam_cv

for the tutorial and got it working, but now when I have
IplImage* image = raspiCamCvQueryFrame(capture);
cv::cvtColor(cv::Mat(image), x, cv::COLOR_BGR2HSV);
it will compile, but when run it gives

Unrecognized or unsupported array type in function cvGetMat

Without the cv::Mat(image) I can't compile because of

Invalid initialization of reference of type "cv::InputArray" from expression of type "IplImage*"
解决方案
As mentioned in the comments, it's better to use the new C++ interface.

The following code will show the feed from a webcam in a window, the program will terminate when 'q' is pressed: (source)
#include "opencv2/highgui/highgui.hpp"

int main(int argc, const char** argv) {
    cv::VideoCapture capture;
    cv::Mat image;

    // Unless you need to get images from multiple devices,
    // using '-1' will automatically select the webcam.
    capture.open(-1);
    if (capture.isOpened()) {
        cv::namedWindow("WebCam", cv::WINDOW_AUTOSIZE);
        while (1) {
            capture.read(image);
            cv::imshow("WebCam", image);
            int c = cv::waitKey(10);
            if ((char)c == 'q') {
                break;
            }
        }
    }

    capture.release();

    return 0;
}
I have tested this code on Ubuntu 14.04 and compiled it like this:
$ clang++ -o cvtest cvtest.cpp -lopencv_core -lopencv_highgui




If you desperately want to continue using IplImage and the C interface, then I can't help you.
