Dot and Cross Products of Vectors and Matrices

  • Dot and Cross Products of Vectors and Matrices
  • Matrix dot product: is the multiplication of the corresponding elements of the matrix
  • Matrix cross product: Matrix multiplication is the Mth row of matrix A multiplied by the Nth column of matrix B. Each element is multiplied and summed as the values of the Mth row and column.


Geometric Description of Camera Imaging

  • Why is it common to see the image plane in front of the camera's optical center: Generally, in order to simplify the model, we uniformly symmetric the imaging plane to the front of the optical center of the camera, so that the imaging plane and three-dimensional space points are placed on the same side of the camera coordinate system, which is called virtual image.
