Embodiment 1

[0058] This embodiment provides a physiological signal remote monitoring system based on multi-modal imaging technology, based on multi-modal imaging technology, including thermal imaging device, visible light imaging device, near-infrared imaging device, laser biological speckle imaging device and hyperspectral imaging device. In order to make the system more compact, small and portable, the first four are placed in the integrated imaging module 9 of the system, and the hyperspectral imaging device is placed separately in a hyperspectral imaging module 11 due to its relatively large equipment. The specific layout is as follows figure 1 shown.

[0059] 1) Thermal imaging device: a far-infrared camera 1 is used, a thermal imaging image is obtained by the far-infrared camera 1 , and the thermal imaging device is placed in an integrated imaging module 9 . Thermal imaging images can be used to extract physiological signal data of heart rate, body surface temperature, respiration...

Embodiment 2

[0089] This embodiment provides an application example of the physiological signal remote monitoring system based on the multimodal imaging technology provided in Embodiment 1.

[0090] like Figure 4 As shown, a sleep monitoring system is provided, and the physiological signal remote monitoring system based on multimodal imaging technology provided in Embodiment 1 is used to perform remote monitoring of physiological signals during sleep.

[0091] In this embodiment, the physiological signal remote monitoring system 13 based on the multimodal imaging technology provided in Embodiment 1 (hereinafter referred to as the multimodal imaging system, the layout diagram is as follows figure 1 shown) is fixed on the ceiling 14 of the room. The working process of the sleep monitoring system is:

[0092] The subject 15 to be tested lies on a bed 16 and is in a sleeping state. The RGB camera 3 in the multi-modal imaging system (13) first obtains an image, and then calculates the compl...

Embodiment 3

[0095] This embodiment gives an application example of another physiological signal remote monitoring system based on multimodal imaging technology provided in Embodiment 1.

[0096] like Figure 5 As shown, this embodiment provides a disease screening system, which uses the physiological signal remote monitoring system based on multi-modal imaging technology provided in Embodiment 1 to collect physiological signals to determine health status.

[0097] Taking the real-time screening and status monitoring of sick pigs in pig farms as an example, the health status of the pigs 19 to be tested in the fence 18 is judged according to the physiological signals remotely obtained by the multi-modal imaging system 13, so as to improve epidemic prevention and control in a timely manner. Economic efficiency and the benefit of the final consumer.

[0098] The actual execution steps of the disease screening system provided in this embodiment are similar to those in Embodiment 2, and will n...

Abstract

The invention provides a physiological signal remote monitoring system based on multimodal imaging technique and application thereof; the physiological signal remote monitoring system comprises an integrated imaging module, a hyperspectral imaging module and a control terminal; the hyperspectral imaging module is disposed above the integrated imaging module, and the integrated imaging module and the hyperspectral imaging module are respectively in communication connection with the control terminal. The physiological signal remote monitoring system integrating the 5 imaging modes of hyperspectral mode, visible light mode, near-infrared mode, far-infrared mode and laser bio-speckle mode can provide high-precision extraction and analysis for physiological signals; meanwhile, the physiological signal remote monitoring system allows coordinated data acquisition among multimodal devices and coordinated processing and analysis among data, such that the different application needs such as sleep monitoring and diseased pig screening are met.

Description

technical field [0001] The invention relates to the technical field of imaging and image processing, in particular to a high-precision remote monitoring system for physiological signals based on multi-modal imaging technology and its application. Background technique [0002] Physiological signals are a group of functional indicators that measure the real-time physiological conditions of living organisms and their operating states. The physiological signal index group mainly includes heart rate, respiration rate, temperature and blood oxygen content, etc., and its value is greatly affected by the age, gender, weight, exercise situation and physical state of the living body. Therefore, the monitoring of physiological signals has been widely used in medicine. In addition, newer studies have shown that physiological signals can be used as one of the apparent reflection indicators of mental state, so it has also received great attention in the field of psychology. [0003] Mos...
