Problems solved by technology

However, this device still needs to tie the straps to the legs of the infant, which is somewhat restrictive. Moreover, as long as the infant turns the leg, the alarm will sound regardless of whether the quilt is kicked, and the false alarm rate is high.

Embodiment Construction

[0025] see figure 1 , is an embodiment of the sleeping posture recognition method of the present invention.

[0026] To make the description clearer, the space to be measured and the measurement space are defined: when there is no object to be measured in the space to be measured, it is called the space to be measured; when there is an object to be measured in the space to be measured, it is called the measurement space.

[0027] In the present embodiment, baby is used as the object to be cared for, and the sleeping position recognition method includes the following steps:

[0028] S100: The bone information collection unit obtains the joint point information of each joint of the baby, please refer to 2. This step is specifically:

[0029] S101: The depth-of-field data acquisition module acquires image depth-of-field data in the measurement space.

[0030] In this embodiment, a somatosensory (kinect) device may be used to acquire image depth data of the measurement space.

Abstract

The embodiment of the invention provides a sleeping posture identification method and a sleeping posture identification device. The sleeping posture identification method comprises the following steps of acquiring the joint information of each joint of a nursed object in a measurement space; and judging whether the sleeping posture of the nursed object is abnormal or not according to the acquired joint information, and giving an alarm if the sleeping posture of the nursed object is abnormal. According to the sleeping posture identification method and the sleeping posture identification device, the joint information of the nursed object is used for judging whether the sleeping posture of the nursed object is abnormal or not in a sleeping posture identification process, so that the abnormal sleeping posture judgment accuracy is high, the false alarm probability is lower, and the time and the energy of a caregiver are saved; and moreover, the sleeping posture identification device is not required to contact with the nursed object, so that constraints to the nursed object are avoided.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a sleeping posture recognition method and device for automatically recognizing human sleeping postures. Background technique [0002] Due to dishonest sleep, infants and young children often have abnormal sleep phenomena such as kicking quilts, uncovering their stomachs, covering their faces with clothes, and sleeping on their stomachs. Choking problem. Therefore, some caregivers will use baby anti-kick quilts for infants, but this anti-kick quilt will restrain the physical activities of infants and young children, which not only makes infants feel uncomfortable, but also is not conducive to the development of infants and young children. In the prior art, a baby is kicked to be reminded, and the vibration sensor is tied to the baby's leg through a strap. When the baby's leg turns, the vibration sensor senses the vibration and transmits the signal to the alarm through the wire. The alarm n...
