Definitions

  • the present invention can provide an information processing apparatus, an information processing method, and a program that can more accurately detect the state of a person on the bed by being configured as described above.
  • the distance image camera C captures a distance image with a pixel value as a distance value.
  • the distance image camera C may be of a type that measures the distance from the round-trip time when the infrared laser is projected onto the target, or may be of any type.
  • the distance image camera C has a function of photographing a distance image at a constant time interval or at a timing when a photographing instruction is received, and transmitting the distance image to the monitoring server 10 described later.
  • the person detection unit 13 (detection means) performs a process of detecting the person P in the distance image 21. At this time, the person detection unit 13 first detects an object present in the distance image 21, and detects a pair of the head P1 and the body part P2 of the person P from the object (step S2 in FIG. 6).
  • the person detection unit 13 may detect the pair of the head P1 and the body part P2 of the person P from the distance image 21 by any method.
  • the person detection unit 13 detects other parts such as a leg part and an arm part of the person P based on a separately provided standard
  • the part P also includes the head P1 and the torso part P2 of the same person P. May be associated with a pair. And based on these other site
  • the determination unit 14 detects, for example, the center positions of the head P1 and the torso part P2 on the distance image 21, the center position based on a predetermined reference, and the upper vertex position, and the center position and the center position are detected.
  • the position and the vertex position are used as the positions of the head P1 and the torso P2 of the person P.
  • the positions of the centers of gravity are used as the positions of the person's head P1 and torso P2.
  • the center of gravity position may be used as the position of the head P1 or the torso P2. Good.
  • the example in the upper right diagram and the lower right diagram in FIG. 4 shows a case where the person P stands on the bed B (standing position).
  • the pair of the head portion P1 and the torso portion P2 of the person P is stacked above the bed B, the position of the torso portion P2 is positioned higher than the height position of the bed B, and the position of the head portion P1 is It will be located higher.
  • the determination unit 14 has a positional relationship in which the pair of the head P1 and the torso part P2 that follow in the distance image 21 is stacked above the bed B, and the positions of the head P1 and the torso part P2 are the positions of the bed B, respectively. If the position is higher than the height position, the posture of the person P is determined to be standing.
  • the example in the upper right diagram and the lower right diagram in FIG. 5 shows a case where the person P leaves the bed B (gets out of bed).
  • the pair of the head P ⁇ b> 1 and the body part P ⁇ b> 2 of the person P is located away from the area of the bed B.
  • the determination unit 14 determines that the posture of the person P is out of bed. Judge that there is.
