[0041] Configuration of behavior detection system

[0042] figure 1 is a block diagram showing the functional configuration of devices included in the behavior detection system according to the first embodiment. figure 1 The behavior detection system 1 shown is suitable for use in healthcare facilities. Using the images captured by the camera 20, the behavior detection system 1 provides a service for detecting motion related to the behavior of the user of the bed, such as patients and persons in need of care leaving the bed (eg, standing).

[0043] As part of such a behavior detection service, the behavior detection system 1 dynamically sets a line for determining leaving the bed based on the predicted head movement path when the user stands from a forward bending posture, and determines whether the head passes the line, the The forward bending posture is detected from images captured by the camera 20 .

[0044] Therefore, even if the line for determining leaving the bed is...

[0133] One embodiment has been described above in relation to the disclosed device. However, the present invention can be practiced in various other forms than the above-described embodiments. Other embodiments included in the present invention will be described below.

[0134] Waking up line setting

[0135] In the first embodiment described above, the behavior detection processing was described as being performed with the forward bending line always activated on the image. However, the forward bending line does not always need to be set to the on state. Then, a case will be described below in which a wake-up line for determining whether the patient is in a recumbent position or a sitting position is set, and if the head is within the wake-up line, the forward bending line is not activated.

[0136] Figure 17 is a diagram showing an example of a method for setting a wake-up line. Figure 17 The top of is shown four vertices P1 to P4 comprised by the bed surface of bed 3...

Abstract

A behavior detection apparatus detects a position of a head from an image; based on the position of the head, detects a motion of bending forward when a person to be detected sits up in a width direction of a bed in a bed area of the image and stands up from the sitting state; when a movement of the head is detected to be forward bending, sets, based on a movement path of the head, a stand-up detection line for determining bed leaving of the person between a lowest point of the forward bending and the position of the head when the person stands by the bed, the stand-up detection line being set in a position not overlapping with a forward bending detection line by which the motion of bending forward is detected; and detects a stand-up motion when the head passes the set stand-up detection line.

Description

technical field [0001] The embodiments discussed here relate to a behavior detection method and a behavior detection device. Background technique [0002] In a medical care facility, accidents such as trances and falls can occur when a patient leaves his / her bed without the caregiver noticing. In order to suppress the occurrence of such an accident, a technique for detecting motion (such as standing) associated with the patient getting out of the bed has been proposed. [0003] For example, a camera device for capturing the patient's head and the like is installed above the head side of the bed, such as directly above the headboard. The patient's departure from the bed or the like is detected based on whether or not the position of the head detected from the image captured by the camera exceeds a line set at both ends of the reference bed.
