我是新手使用HOG探测器在路上探测人类,我已经编写了代码并尝试运行它,但它总是出现错误:“hog.setSVMDetector(HOGDescriptor: :getDefaultPeopleDetector());”这一行,任何人都可以告诉我我的代码有什么问题吗?
#include < stdio.h>
#include < iostream>
#include < opencv2\opencv.hpp>
#include < opencv2/core/core.hpp>
#include < opencv2/highgui/highgui.hpp>

#include <opencv2/imgproc.hpp>

#include <peopledetect.cpp>
using namespace cv;
using namespace std;
int main(int argc, const char * argv[])
{
VideoCapture cap(0);
cap.set(CV_CAP_PROP_FRAME_WIDTH, 320);
cap.set(CV_CAP_PROP_FRAME_HEIGHT, 240);
if (!cap.isOpened())
return -1;
Mat img;
namedWindow("opencv", CV_WINDOW_AUTOSIZE);
HOGDescriptor hog;
hog.setSVMDetector(HOGDescriptor::getDefaultPeopleDetector());
while (true)
{
cap >> img;
if (img.empty())
continue;
vector<Rect> found, found_filtered;
hog.detectMultiScale(img, found, 0, Size(8, 8), Size(32, 32), 1.05, 2);
size_t i, j;
for (i = 0; i<found.size(); i++)
{
Rect r = found[i];
for (j = 0; j<found.size(); j++)
if (j != i && (r & found[j]) == r)
break;
if (j == found.size())
found_filtered.push_back(r);
}
for (i = 0; i<found_filtered.size(); i++)
{
Rect r = found_filtered[i];
r.x += cvRound(r.width*0.1);
r.width = cvRound(r.width*0.8);
r.y += cvRound(r.height*0.07);
r.height = cvRound(r.height*0.8);
rectangle(img, r.tl(), r.br(), Scalar(0, 255, 0), 3);
}
imshow("opencv", img);
waitKey(1);
}
return 0;
}
答案 0 :(得分:1)
通常,您不应该在C ++程序中包含.cpp文件。有.h和.hpp标题。
现在,对于您的特定问题,如果我们正在讨论相同的peopledetect.cpp,那么您所需的函数不是在那里定义的,而是在那里包含的标题中...您可能已经有了正确的标题(objdetect.hpp )所以只需删除#include <peopledetect.cpp>
