假设我有一个std::vector<Point>,其中Point是struct Point { double x; double y;},我想将这样的向量划分为组(桶),其中同一桶中的所有点彼此具有相同的欧几里得范数我决定使用std::map和自定义排序操作符来完成这样的任务:{ bool operator()(Point const& A, Point const&false : std::t ...

If you want a vector of points, then make a vector of points. 1 2 3 4 5 structpoint_2d{doublex[2]; }; vector<point_2d> datum_; Oct 13, 2011 at 2:38am Kase(12) Ne555, I don't quite understand your answer yet. If I have the vector of points like you wrote, is push_back...

std::vector<DOUBLEPOINT> 我正在使用贝塞尔曲线进行应用,结果会实时显示。我将贝塞尔点转换成一堆短线。我在上面的向量中存储了小行的坐标。这是我的问题:当我的向量大小超过缓存行时,事情变得非常缓慢。我想知道是否有更多的 std::vector<DOUBLEPOINT>
要打印std::vector<cv::KeyPoint>中的每个元素,你可以使用C++的迭代器来遍历vector并逐个打印每个元素。cv::KeyPoint是一个包含特征检测和描述符提取的类,其包含的信息如尺度、角度、响应、octave和x,y坐标等。 以下是一个如何打印std::vector<cv::KeyPoint>中元素的示例: ...
