opencv将图片转为HSV时总是报错

Question

if(m_pVideoInfo->m_pCapture){
IplImage* frame,*src_image=NULL;
frame = cvQueryFrame(m_pVideoInfo->m_pCapture);
if(frame)
{
cvCopy(frame,m_pVideoInfo->m_pFrameImage);
int i, bin_w, c;
if(!m_pVideoInfo->m_pFrameImage)
{
m_pVideoInfo->m_pFrameImage = cvCreateImage( cvGetSize(frame), 8, 3 );//
m_pVideoInfo->m_pFrameImage->origin = frame->origin;
hsv = cvCreateImage( cvGetSize(frame), 8, 3 );
hue = cvCreateImage( cvGetSize(frame), 8, 1 );
mask = cvCreateImage( cvGetSize(frame), 8, 1 );//分配掩膜图像空间
backproject = cvCreateImage( cvGetSize(frame), 8, 1 );//分配反向投影图空间，大小一样，单通道
hist = cvCreateHist( 1, &hdims, CV_HIST_ARRAY, &hranges, 1 ); //分配建立直方图空间

      histimg = cvCreateImage( cvSize(320,200), 8, 3 );//分配用于画直方图的空间
     cvZero( histimg );//背景为黑色
    }
    cvCopy( frame, m_pVideoInfo->m_pFrameImage, 0 );
    cvCvtColor( m_pVideoInfo->m_pFrameImage, hsv, CV_BGR2HSV ); // 把图像从RGB表色系转为HSV表色系

这是MFC程序中的一部分，capture指针打开了一个视频文件

但是每次打开视频的时候都会报错，只要把最后一段代码注释了就没问题了

 #include <math.h>
#include "highgui.h"
#include "cv.h"
#include "time.h"
#include <iostream>


int main()
{
    IplImage* image = cvLoadImage("test.png");  
    IplImage* hsv = cvCreateImage( cvGetSize(image), 8, 3 );
    cvCvtColor(image,hsv,CV_BGR2HSV);

    cvNamedWindow("saturate_SV",CV_WINDOW_AUTOSIZE);  
    cvShowImage("saturate_SV",hsv);  
    cvWaitKey(0);  
    cvReleaseImage(&hsv);  
    cvDestroyWindow("saturate_SV");  
    return 0;
}
