A rotation vector is aconvenient and most compact representationof a rotation matrix (since any rotation matrix has just 3 degrees of freedom). The representation is used in the global 3D geometry optimization procedures like calibrateCamera, stereoCalibrate, or solvePnP . 称旋转向量是旋转矩阵方便而且...

You are given annxn2D matrix representing an image. Rotate the image by 90 degrees (clockwise). Follow up: Could you do this in-place? 原地图像顺时针旋转90度。由于要求空间复杂度是常数,因此应该迭代旋转操作。 class Solution { public: void rotate(vector<vector<int> > &matrix) { int n = ...
在数学中,"rotate"可以用来描述向量或坐标系的旋转变换。 - To rotate a vector by 90 degrees counterclockwise, you can multiply it by a rotation matrix. (要逆时针旋转一个向量90度,你可以将它乘以一个旋转矩阵。) 这些是"rotate"的基本用法,但实际应用可能会根据上下文有所不同。©...

1、reverse第一个数组到最后一个数组 2、对右上角三角形区域,做matrix[i][j]与matrix[j][i]换值 若是反时钟方向,则是对左上角三角形区域做转换。 void rotate(vector<vector<int>>& matrix) { int n = matrix.size(); reverse(matrix.begin(), matrix.end()); ...
