This paper introduces an automatic non-contact monitoring method for measuring the respiratory rate of neonates using a structured light camera. The current monitoring bears several issues causing pressure marks, skin irritations and eczema. A structured light camera provides distance data. Our non-contact approach detects the thorax area automatically using a plane segmentation and calculates the respiratory rate from the movement of the thorax. Our method was tested and validated using the baby simulator SimBaby by Laerdal. We used different breathing rates corresponding to preterm neonates, mature neonates and babies aged up to nine months as well as two different breathing modes with differing breathing strokes. Furthermore, measurements were taken of two positions: the baby lying on its back and on its stomach.
本文介绍了一种使用结构光相机测量新生儿呼吸频率的自动非接触监测方法。目前的监测存在一些问题，会导致压痕、皮肤刺激和湿疹。结构光相机可提供距离数据。我们的非接触方法通过平面分割自动检测胸部区域，并根据胸部的运动计算呼吸频率。我们的方法使用Laerdal公司的婴儿模拟器SimBaby进行了测试和验证。我们使用了对应于早产儿、足月儿和九个月以下婴儿的不同呼吸频率，以及两种具有不同呼吸冲程的不同呼吸模式。此外，还在两个位置进行了测量：婴儿仰卧和俯卧。
