每次我想使用 Generate3DProfile 函数时,条件是生成应该从当前索引开始,我在内存位置 0x0024EFD4 出现 cv::Exception 错误,直到 if(!imgused[i]) continue; . 但是当我对整个序列进行生成时没有错误,这是代码的重要部分:
void TPictureWindow::Generate3DProfile()
{
char buffer[MAX_PATH];
int value, newHeight, newWidth, refYpos = 0;
IplImage* transformB = cvCreateImage(cvSize(m_imgSequence[0]->width, NumImages), IPL_DEPTH_8U, 1);
IplImage* transformG = cvCreateImage(cvSize(m_imgSequence[0]->width, NumImages), IPL_DEPTH_8U, 1);
IplImage* transformR = cvCreateImage(cvSize(m_imgSequence[0]->width, NumImages), IPL_DEPTH_8U, 1);
cvZero(transformB);
cvZero(transformG);
cvZero(transformR);
for(int i = 0; i < NumImages; i++)
{
if(!imgused[i]) continue;
for(int j = 0; j < edge[i][0]->total; j++)
{
MessageBox("hallo", "", MB_OK);
CvPoint* pt1 = CV_GET_SEQ_ELEM(CvPoint, edge[i][0], j);
CvPoint* pt2 = CV_GET_SEQ_ELEM(CvPoint, edge[i][1], j);
value = (pt1->y-pt2->y)*1000*scaling;
//sprintf_s(buff3,"%d", value);
//MessageBox(buff3, "", MB_OK);
if(value < 0) value = 0;
transformB->imageData[i*transformB->widthStep+pt1->x] = value%256;
transformG->imageData[i*transformG->widthStep+pt1->x] = value/256;
}
}
IplImage* final = cvCreateImage(cvSize(m_imgSequence[0]->width, NumImages), IPL_DEPTH_8U, 3);
cvMerge(transformB, transformG, transformR, NULL, final);
cvFlip(final,final);
if(isFirst){
cvSaveImage(outFileName, final);
isFirst = false;
}else{
//sprintf_s(buffer, "%s%04d%s", TempFileName, prevIndex, ".tif");
IplImage* tempPrev = cvLoadImage(outFileName,CV_LOAD_IMAGE_COLOR);//name ändern
if(imgIndex/100 == prevIndex/100){
newHeight = tempPrev->height >= final->height*(imgIndex%100+1)?tempPrev->height : tempPrev->height+final->height;
newWidth = tempPrev->width;
newYpos = (imgIndex/100)%2 > 0 ? newYpos-final->height : newYpos+final->height;
if(newYpos < 0){
newYpos = 0;
refYpos = final->height;//fall dass es unten noch weitere blöcke gibt
}
}else{
newHeight = tempPrev->height;
newWidth = tempPrev->width+final->width;
newXpos += final->width;
}
IplImage* temp2 = cvCreateImage(cvSize(newWidth, newHeight), IPL_DEPTH_8U, 3);
cvZero(temp2);
cvSetImageROI(temp2, cvRect(0,refYpos, tempPrev->width, tempPrev->height));
cvCopy(tempPrev, temp2);
cvSetImageROI(temp2,cvRect(newXpos, newYpos, final->width, final->height));
cvCopy(final, temp2);
cvResetImageROI(temp2);
cvSaveImage(outFileName, temp2);
}
//sprintf_s(buffer, "%s%04d%s", TempFileName, imgIndex, ".tif");
PostMessage(READY_WITH, IMG_3D_PROFILE, 0);
}
更新部分:
哦,好吧,我发现应该是 1 或 0 的 imgused 的值确实是 69,这很奇怪。在我的代码的其他部分,这种使用方式是有效的。这里的声明部分:class TPictureWindow :
public TWindow
{
private:
bool isBorders, isDoWhiteLine, isLoaded, isMultiple, useRoi4all, canBuild, isFirst;
char TempFileName[MAX_PATH], outFileName[MAX_PATH];
unsigned int NumImages, ImgWidth, ImgHeight;
int refracidx, lini, actualPicIndex, newindex, imgIndex, abort, prevIndex, newXpos, newYpos;
bool imgused[MAX_IMAGES];
double scaling, deltaX, deltaY;
