Hello !
我在使用 imgproc.hpp 文件中的cornerSubPix 方法时遇到问题。
我不明白缺少哪个库或者有什么错误。
我在 OS X 10.10.3 上使用 Qt 5.4.1，并使用 OpenCV 3.0.0 C++ 库。
这是我的代码：
#include <opencv2/opencv.hpp>
#include <opencv2/core/types.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc.hpp>
#include <opencv2/features2d/features2d.hpp>
#include <vector>
#include <stdio.h>
#include "cameraparams.h"
#include <iostream>
[...]
vector< vector <Point2f> > left_2D_points, right_2D_points;
for( int i=0;i<left_images.size();i++){
Mat left_image = left_images[i];
Mat rig
ht_image = right_images[i];
std::vector<cv::Point2f> left_im_points,right_im_points;
bool found_left = findChessboardCorners(left_image,Size(width,height),left_im_points,CALIB_CB_ADAPTIVE_THRESH + CALIB_CB_NORMALIZE_IMAGE+ CALIB_CB_FAST_CHECK);
bool found_right = findChessboardCorners(right_image,Size(width,height),right_im_points,CALIB_CB_ADAPTIVE_THRESH + CALIB_CB_NORMALIZE_IMAGE+ CALIB_CB_FAST_CHECK);
if( found_left && found_right){
Size winSize = Size( 7, 7 );
Size zeroZone = Size( -1, -1 );
TermCriteria criteria = TermCriteria( TermCriteria::EPS + TermCriteria::MAX_ITER, 40, 0.001 );
cv::cornerSubPix(left_image,left_im_points,winSize,zeroZone,criteria);
}
}
这是我的 *.pro 文件：
INCLUDEPATH += /usr/local/include/ \
/usr/local/include/pcl-1.7/ \
/usr/local/include/eigen3/ \
/usr/local/include/vtk-6.2/
LIBS += -L/usr/local/lib \
-lopencv_core \
-lopencv_imgcodecs \
-lopencv_highgui \
-lopencv_imgproc \
-lopencv_objdetect \
-lopencv_calib3d \
-lopencv_features2d \
-lopencv_flann \
-lopencv_ml \
-lopencv_photo \
-lopencv_shape \
-lopencv_stitching \
-lopencv_superres \
-lopencv_ts \
-lopencv_video \
-lopencv_videoio \
-lopencv_videostab
所以我想更精确地检测棋盘上的角点。但是当我编译时出现此错误：
Undefined symbols for architecture x86_64:
"cv::_InputArray::getMatVector(std::vector<cv::Mat, std::allocator<cv::Mat> >&) const", referenced from:
vtable for cv::_InputOutputArray in calibrator.o
"cv::_InputArray::getUMatVector(std::vector<cv::UMat, std::allocator<cv::UMat> >&) const", referenced from:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我几天来一直在寻找答案，但我已经被屏蔽了。
预先感谢大家的任何线索！
