[英]Change OpenCV image format to matlab format, debug assertion __acrt_first_block == header
我试图将OpenCV图像（类型为cv :: Mat）转换为matlab样式格式，因为这是程序的其余部分所要求的。 我使用以下代码来做到这一点：
inline double* ConvertCVImageToMATLABImage(Mat &CvImage)
{
std::vector<cv::Mat> ColorChannels; // B, G, R channels
cv::split(CvImage, ColorChannels);
// remember to tranpose first because MATLAB is col-major!!!
cv::transpose(ColorChannels[0], ColorChannels[0]);
cv::transpose(ColorChannels[1], ColorChannels[1]);
cv::transpose(ColorChannels[2], ColorChannels[2]);
double *MatlabImage = new double[CvImage.rows*CvImage.cols * 3];
int CounterCompleteImage = 0;
int CounterEachColorChannel = 0;
for (CounterEachColorChannel = 0; CounterEachColorChannel<CvImage.rows*CvImage.cols; ++CounterEachColorChannel, ++CounterCompleteImage)
{
MatlabImage[CounterCompleteImage] = static_cast<double>(ColorChannels[2].data[CounterEachColorChannel]);
}
for (CounterEachColorChannel = 0; CounterEachColorChannel<CvImage.rows*CvImage.cols; ++CounterEachColorChannel, ++CounterCompleteImage)
{
MatlabImage[CounterCompleteImage] = static_cast<double>(ColorChannels[1].data[CounterEachColorChannel]);
}
for (CounterEachColorChannel = 0; CounterEachColorChannel<CvImage.rows*CvImage.cols; ++CounterEachColorChannel, ++CounterCompleteImage)
{
MatlabImage[CounterCompleteImage] = static_cast<double>(ColorChannels[0].data[CounterEachColorChannel]);
}
return MatlabImage;
}
它与调试断言崩溃：
__acrt_first_block == header
在最后一行（返回MatlabImage）。 追溯断言的来源，它似乎与解除分配矢量ColorChannels有关。 我尝试了多种方法，即使用.clear，使用交换技巧，或者解除分配向量中的每个项目，但断言仍然存在。
如果嵌入到C ++程序的主函数中，这段代码可以很好地工作，在专用函数中就不会这样。
我简化了main函数，它将上面的代码调用到最低限度：
void main(void)
{
cv::Mat CvImage = imread("E:\\VOC2012\\VOCdevkit\\VOC2012\\JPEGImages\\2008_000027.jpg", CV_LOAD_IMAGE_COLOR); // Read the file
double* Image = ConvertCVImageToMATLABImage(CvImage);
}
问题依然存在：
我正在使用Visual Studio 2015.它在发布模式下运行良好但在调试模式下抛出调试断言（显然），特别是它指向debug_heap.cpp，第980行。
谢谢Pat
配置opencv并关闭“BUILD_WITH_STATIC_CRT”，默认情况下为on。 当我从一个单独的线程调用detectMultiScale时，我得到了相同的断言失败，并且调用函数返回，直到我重新编译打开该标志的opencv。
使用Visual Studio 2015构建的代码，我得到你的调试断言__acrt_first_block == header 。
下面的代码没有给出断言，我只是更改了std::vector<cv::Mat> ColorChannels; to cv::Mat ColorChannels[3]; 。
我认为我的解决方案快速而且肮脏，也许iedoc提供的解决方案更好（我没有测试它）。
#include "opencv2/core/core.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/highgui/highgui.hpp"
inline double* ConvertCVImageToMATLABImage(cv::Mat &CvImage)
{
cv::Mat ColorChannels[3]; // B, G, R channels
cv::split(CvImage, ColorChannels);
// remember to tranpose first because MATLAB is col-major!!!
cv::transpose(ColorChannels[0], ColorChannels[0]);
cv::transpose(ColorChannels[1], ColorChannels[1]);
cv::transpose(ColorChannels[2], ColorChannels[2]);
double *MatlabImage = new double[CvImage.rows*CvImage.cols * 3];
int CounterCompleteImage = 0;
int CounterEachColorChannel = 0;
for (CounterEachColorChannel = 0; CounterEachColorChannel<CvImage.rows*CvImage.cols; ++CounterEachColorChannel, ++CounterCompleteImage)
{
MatlabImage[CounterCompleteImage] = static_cast<double>(ColorChannels[2].data[CounterEachColorChannel]);
}
for (CounterEachColorChannel = 0; CounterEachColorChannel<CvImage.rows*CvImage.cols; ++CounterEachColorChannel, ++CounterCompleteImage)
{
MatlabImage[CounterCompleteImage] = static_cast<double>(ColorChannels[1].data[CounterEachColorChannel]);
}
for (CounterEachColorChannel = 0; CounterEachColorChannel<CvImage.rows*CvImage.cols; ++CounterEachColorChannel, ++CounterCompleteImage)
{
MatlabImage[CounterCompleteImage] = static_cast<double>(ColorChannels[0].data[CounterEachColorChannel]);
}
return MatlabImage;
}
#include <iostream>
int main(int,char**)
{
std::cout << cv::getBuildInformation();
cv::Mat CvImage = cv::imread("c:\\img\\2008_000027.jpg", CV_LOAD_IMAGE_COLOR); // Read the file
double* Image = ConvertCVImageToMATLABImage(CvImage);
return 0;
}
