Definitions

  • the information processing apparatus 1 detects the part of the human body that has come into contact with the ball and the position on the ball that the part of the human body has come into contact with (S13). For example, the information processing apparatus 1 detects a position on the ball such that the inside of the right foot (inside of the right foot) comes into contact with the right side surface of the ball.
  • the "part of the human body” is a part defined by a line segment connecting two adjacent joints.
  • the part represented by the line segment connecting the heel and the big toe can be defined as the inside of the foot.
  • the first detection unit 102 detects the center position and radius of the ball in the image by analyzing the image.
  • the first detection unit 102 uses, for example, a conventional technique capable of outputting coordinate data indicating a rectangular box 10 (including a square) indicating a position in which a ball is shown in an image, thereby performing the coordinate data. To get. Further, the first detection unit 102 may set the center of the rectangular box 10 (the average value of the coordinates of the four vertices of the rectangular box 10) as the center position of the ball. Further, the ball radius may be a value obtained by halving the average value of the vertical length and the horizontal length of the rectangular box 10.
  • FIG. 5 is a diagram for explaining an example of processing for detecting the position of each part of the human body shown in the image.
  • the processing procedure in step S11 of FIG. 2 will be described with reference to FIG.
  • the first detection unit 102 detects the position of each skeleton of the human body by analyzing the image.
  • the first detection unit 102 detects the position of each skeleton of the human body by using the conventional technique capable of outputting the position of the skeleton of the human body shown in the input image. May be good.
  • the left-right direction is defined based on the state in which the user to be detected faces the front, but the present invention is not limited to this. The left and right may be reversed.
  • step S108 the second detection unit 103 determines that the user has touched the left side of the ball at the portion X.
  • step S110 the second detection unit 103 determines that the user has touched the lower side of the ball at the portion X.
  • the evaluation unit 104 sets the timing at which each ball touch is performed within a predetermined time range (for example, plus or minus 0.7 seconds, etc.). ), And if the specific part in contact with the ball and the position on the ball in contact with the specific part match, the score may be added (for example, +1).
  • the predetermined time range is set to 0.7 seconds.
  • the user makes the third ball touch 0.35 seconds after the second ball touch.
  • the timing is within a predetermined time range.
  • the specific portion in contact with the ball and the position on the ball in contact with the specific portion match with the model and the user's action. Therefore, the evaluation unit 104 adds 1 to the score.
  • the information processing apparatus 1 identifies and analyzes the center position of the ball, the radius of the ball, and the position of each part of the user's foot by recognizing the moving image as an image for each frame. , Which part of the user's foot touched which position on the ball was detected. This enables the information processing device 1 to detect the position where the user touches the ball and the portion of the foot that touches the ball.
