specific Embodiment approach 1
[0029] Specific implementation mode one: the following combination figure 1 and image 3 Describe this embodiment, the long-distance face collection method described in this embodiment, the face collection equipment involved in this method includes PC 1, binocular camera 2, two-degree-of-freedom rotating platform 3 and telephoto camera 4, long-distance The focal camera 4 is arranged on the two-degree-of-freedom rotating platform 3, and it is characterized in that, described long-distance face collection method comprises the following steps:
[0030] Step 1, the binocular camera 2 collects the target face to determine the three-dimensional coordinates of the target face, and feeds back to the PC 1;
[0031] Step 2, PC 1 adjusts the two-degree-of-freedom rotating platform 3 according to the three-dimensional coordinate output command of the target face, so that the two-degree-of-freedom rotating platform 3 drives the telephoto camera 4 to align with the direction of the target ...
specific Embodiment approach 2
[0049] Specific implementation mode two: this implementation mode further explains implementation mode one, adopts to track target face based on condensation algorithm in step five, and the process of updating the two-dimensional pixel coordinates of target face in video is:
[0050] Step 51. Select N particles in the target face area in the current frame image of the video information to construct a particle swarm at the k-1th moment { s k - 1 ( n ) , π k - 1 ( n ) , n = 1,2 · · · N } ,
[0051] Wherein, N is a positive integer, and N=200~2000, is the coordinates of the nth parti...
specific Embodiment approach 3
[0070] Specific implementation mode three: this implementation mode further explains implementation mode two, and N=300.
