Extract control points from the projected silhouette of a mesh

see drummond2002real Sec 2.1, Step b

ยงParameters

  • num: number of control points
  • len: search radius (used to restrict the ROI)
  • pts3d: the 3D points of the mesh
  • rvec: rotation between mesh and camera
  • tvec: translation between mesh and camera
  • K: camera intrinsic
  • imsize: size of the video frame
  • tris: triangle face connectivity
  • ctl2d: the 2D locations of the control points
  • ctl3d: matching 3D points of the mesh
