在project1.exe 0x52f9e470未处理的异常：0xC000001D：非法指令

Question

我想在C++中使用opencv检测对象，但我得到一个错误： 在project1.exe中0x52f9e470未处理的异常：0xC000001D：非法指令。

使用Windows 7 32位，OpenCV的2.4.3，视觉工作室（C++）2010年和我的代码是：

#include <opencv\cv.h> 
    #include <opencv\highgui.h> 
    #include <stdio.h> 
    #include <stdlib.h> 
    #include <string.h> 
    #include <assert.h> 
    #include <math.h> 
    #include <float.h> 
    #include <limits.h> 
    #include <time.h> 
    #include <ctype.h> 


     // Create a string that contains the exact cascade name 
    // Contains the trained classifer for detecting hand 
    const char *cascade_name="D:/31dec12/hand.xml"; 

    //The function detects the hand from input frame and draws a rectangle around the   detected portion of the frame 
    void detect_and_draw(IplImage* img) 
    { 

    // Create memory for calculations 
    static CvMemStorage* storage = 0; 

    // Create a new Haar classifier 
    static CvHaarClassifierCascade* cascade = 0; 

    // Sets the scale with which the rectangle is drawn with 
    int scale = 1; 

    // Create two points to represent the hand locations 
    CvPoint pt1, pt2; 

    // Looping variable 
    int i; 

    // Load the HaarClassifierCascade 
    cascade = (CvHaarClassifierCascade*)cvLoad(cascade_name, 0, 0, 0); 

    // Check whether the cascade has loaded successfully. Else report and error and  quit 
    if(!cascade) 
    { 
     fprintf(stderr, "ERROR: Could not load classifier cascade\n"); 
    return; 
    } 

    // Allocate the memory storage 
    storage = cvCreateMemStorage(0); 

    // Create a new named window with title: result 
    cvNamedWindow("result", 1); 

    // Clear the memory storage which was used before 
    cvClearMemStorage(storage); 

    // Find whether the cascade is loaded, to find the hands. If yes, then: 
    if(cascade) 
    { 

     // There can be more than one hand in an image. So create a growable sequence of hands. 
     // Detect the objects and store them in the sequence 
     CvSeq* hands = cvHaarDetectObjects(img, cascade, storage, 
             1.1, 2, CV_HAAR_DO_CANNY_PRUNING, 
             cvSize(40, 40)); 

     // Loop the number of hands found. 
     for(i = 0; i < (hands ? hands->total : 0); i++) 
     { 
     // Create a new rectangle for drawing the hand 
     CvRect* r = (CvRect*)cvGetSeqElem(hands, i); 

      // Find the dimensions of the hand,and scale it if necessary 
      pt1.x = r->x*scale; 
     pt2.x = (r->x+r->width)*scale; 
     pt1.y = r->y*scale; 
     pt2.y = (r->y+r->height)*scale; 

     // Draw the rectangle in the input image 
     cvRectangle(img, pt1, pt2, CV_RGB(230,20,232), 3, 8, 0); 
     } 
    } 

    // Show the image in the window named "result" 
     cvShowImage("result", img); 


    } 


    // A Simple Camera Capture Framework 
    int main() 
    { 

    // Gets the input video stream from camera 
    CvCapture* capture = cvCaptureFromCAM(CV_CAP_ANY); 

    // Checks if the input stream is obtained 
    if(!capture) 
    { 
    fprintf(stderr, "ERROR: capture is NULL \n"); 
    getchar(); 
    return -1; 
    } 

    // Show the image captured from the camera in the window and repeat 
while(1) 
    { 

    // Get one frame 
    IplImage* frame = cvQueryFrame(capture); 

    // Cecks if a frame is obtained 
    if(!frame) 
    { 
    fprintf(stderr, "ERROR: frame is null...\n"); 
    getchar(); 
    break; 
    } 

    // Flips the frame into mirror image 
    cvFlip(frame,frame,1); 

    // Call the function to detect and draw the hand positions 
    detect_and_draw(frame); 

    //If ESC key pressed, Key=0x10001B under OpenCV 0.9.7(linux version), 
    //remove higher bits using AND operator 
    if((cvWaitKey(10) & 255) == 27) 
    break; 
    } 

    // Release the capture device housekeeping 
    cvReleaseCapture(&capture); 

    return 0; 
    } 

Answer 1

你用什么样的CPU？上次我发生错误：0xC000001D：非法指令与代码中使用的SSE指令相关。一些新的SSE指令未在AMD处理器上实现，例如，所以你可以通过在没有SSE支持的情况下重建opencv来解决这个问题。

Answer 2

我使用CV ::垫（...）

同样的异常抛出在 size_t esz = CV_ELEM_SIZE(_type), esz1 = CV_ELEM_SIZE1(_type);

没有那么知道为什么，但来自精确的改变Visual C++项目浮点模式后，当也有这个问题要快，解决问题。
