断言失败在未知函数中../../ocv/opencv/modules/imgproc/src/imgwarp.cpp

嘿，请有人帮我找到这个错误的解决方案：

断言在未知函数中失败../../ocv/opencv/modules/imgproc/src/imgwarp.cpp

我尝试编译此链接中存在的代码： http ： //ipwithopencv.googlecode.com/svn/trunk/ThinPlateSpline/ThinPlateSpline/

即时通讯使用2个类和主要：

这是我的主要代码：

#include "stdafx.h" #include  #include  #include  #include "CThinPlateSpline.h" #include "iostream" using namespace std; int _tmain(int argc, _TCHAR* argv[]) { // load a nice picture cv::Mat img = cv::imread("lena.jpg"); // generate some generic points // usually you would use a interest point detector such as SURF or SIFT std::vector iP, iiP; // push some points into the vector for the source image iP.push_back(cv::Point(50,50)); iP.push_back(cv::Point(400,50)); iP.push_back(cv::Point(50,400)); iP.push_back(cv::Point(400,400)); iP.push_back(cv::Point(256,256)); iP.push_back(cv::Point(150,256)); // push some point into the vector for the dst image iiP.push_back(cv::Point(70,70)); iiP.push_back(cv::Point(430,60)); iiP.push_back(cv::Point(60,410)); iiP.push_back(cv::Point(430,420)); iiP.push_back(cv::Point(220,280)); iiP.push_back(cv::Point(180,240)); // create thin plate spline object and put the vectors into the constructor CThinPlateSpline tps(iP,iiP); // warp the image to dst Mat dst; tps.warpImage(img,dst,0.01,INTER_CUBIC,BACK_WARP); // show images cv::imshow("original",img); cv::imshow("distorted",dst); //cv::waitKey(0); //Sleep(5); cv::waitKey(5000); return 0; } 

这是imagewarp方法：

 void CThinPlateSpline::warpImage(const Mat& src, Mat& dst, float lambda, const int interpolation,const TPS_INTERPOLATION tpsInter) { Size size = src.size(); dst = Mat(size,src.type()); // only compute the coefficients new if they weren't already computed // or there had been changes to the points if(tpsInter == BACK_WARP && !FLAG_COEFFS_BACK_WARP_SET) { computeSplineCoeffs(pSrc,pDst,lambda,tpsInter); } else if(tpsInter == FORWARD_WARP && !FLAG_COEFFS_FORWARD_WARP_SET) { computeSplineCoeffs(pSrc,pDst,lambda,tpsInter); } computeMaps(size,mapx,mapy); remap(src,dst,mapx,mapy,interpolation); } 

链接中还存在其他类也包括CthinPlateSpline.cpp和CthinPlateSpline.h …我真的需要帮助，抱歉我的英语不好

Answer 1

我可以使用OpenCV 2.4.7在我的Mac上运行这些

结果图像是扭曲的lena

我只是改变两个地方如下

首先，我将main.cpp中包含的文件更改为

 #include  #include "CThinPlateSpline.h" #include  #include  

并在CThinPlateSpline.cpp中包含文件成为

 #include  #include  #include "CThinPlateSpline.h" 

我只使用3个文件main.cpp，CThinPlateSpline.cpp和CThinPlateSpline.h

Answer 2

OpenCV中的“断言失败”通常发生在输入Mat的大小不正确时，例如零（空Mat）或小于函数的要求。

您是否介意在cv::Mat img = cv::imread("lena.jpg");之后检查img cv::Mat img = cv::imread("lena.jpg"); 通过img.empty（）或imshow显示img？
