所以我检查了我的指针,我真的不确定这里出了什么问题。我通过引用修改它们的函数传递2个向量向量。这是功能:
bool imageToTips( Mat& img,
vector<vector<int> > & fingertips,
vector<vector<Point> > & hand,
double epsilon,
double theta){
//code
}
这就是所谓的:
Mat depth = _depth;
Mat image = depth.clone();
Mat decon = depth.clone();
vector<vector<int> > fingertips();
vector<vector<Point> > hands();
double epsilon = 50;
double theta = 30;
if (fs::imageToTips(decon, fingertips, hands, epsilon, theta))
{
drawContours(image, hands, -1, Scalar(255,0,0,0));
imshow("KinectFingerProcessing", image);
//more code
}
错误:
/FingerLocator2/main.cpp:47: error: invalid initialization of non-const reference of type 'std::vector<std::vector<int, std::allocator<int> >, std::allocator<std::vector<int, std::allocator<int> > > >&' from a temporary of type 'std::vector<std::vector<int, std::allocator<int> >, std::allocator<std::vector<int, std::allocator<int> > > > (*)()'

我已经尝试制作矢量指针但它没有用。我想我在某个地方使用临时变量或什么......这里有什么问题?
答案 0 :(得分:6)
您不需要()
默认构造变量,否则您将定义一个函数。
vector<vector<int> > fingertips;
vector<vector<Point> > hands;
// ^ loose the ()s
答案 1 :(得分:2)
您应该像这样初始化矢量,而不是'()':
vector<vector<int> > fingertips;
vector<vector<Point> > hands;
