SIFT和SURF检测器为什么会崩溃?
using namespace std;
using namespace cv;
int main(int argc, char *argv[])
{
Mat image = imread("TestImage.jpg");
// Create smart pointer for SIFT feature detector.
Ptr<FeatureDetector> featureDetector = FeatureDetector::create("SIFT");
vector<KeyPoint> keypoints;
// Detect the keypoints
featureDetector->detect(image, keypoints); // here crash
// ...
}
错误是
Segmentation fault (core dumped)
。我使用OpenCV 2.4.8,gcc 4.9和Ubuntu。如果我使用其他类型的功能,它将正常运行。我想念什么? 最佳答案
您是否尝试致电 initModule_nonfree()
?
#include <opencv2/nonfree/nonfree.hpp>
using namespace std;
using namespace cv;
int main(int argc, char *argv[])
{
initModule_nonfree();
Mat image = imread("TestImage.jpg");
// Create smart pointer for SIFT feature detector.
Ptr<FeatureDetector> featureDetector = FeatureDetector::create("SIFT");
vector<KeyPoint> keypoints;
// Detect the keypoints
featureDetector->detect(image, keypoints); // here crash
// ...
}
另外,您也没有检查指针FeatureDetector,该指针可能为空(因为尚未调用initModule)。
