Embodiment Construction

[0033] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0034] The invention provides a non-contact heartbeat detection method based on GPU acceleration, such as figure 1 shown, including the following steps:

[0035] S1. Using the GPU to sample and preprocess the chromaticity change value of the exposed skin of the subject.

[0036] This step specifically includes the following sub-steps:

[0037] S11. Continuously sampling the chromaticity change value of the same part of the exposed skin of the same subject. The exposed skin is not limited to the face, as long as it is the same part of the skin.

[0038] S12. Group each N (N is an integer) sampling values ​​into one group. If the number of samples is less than N, it will continue to cache until the number of samples exceeds N. In the embodiment of the present invention, in order to ensure that enough data is sampled, N is set to 64.

[0039] S13. Tak...

Abstract

The invention discloses a non-contact type heartbeat detection method based on GPU acceleration. The heartbeat rate is calculated based on the GPU acceleration, the parallel computing ability of a GPU can be made use of, based on a skin reflection signal collected by non-contact type acquisition, the heartbeat rate is efficiently calculated in real time, the method can be applied in GPU-integrated computer or a GPU-integrated mobile phone and other GPU-integrated devices, and since the burden of the CPU is reduced, the heartbeat rate can be efficiently calculated in real time.

Description

technical field [0001] The invention belongs to the technical field of machine intelligence, and in particular relates to the design of a non-contact heartbeat detection method based on GPU acceleration. Background technique [0002] Heart rate refers to the frequency at which the human heart beats, usually using the number of heartbeats per minute as the unit. Heartbeat is closely related to people's health and emotional state. It is reported that the heartbeat condition is closely related to many diseases, such as cardiovascular disease and heart disease. Abnormal heart rate is a high-risk factor for many cardiovascular diseases. By measuring it, the occurrence of many cardiovascular diseases can be predicted, so that Start diagnosis and treatment as soon as possible to obtain better curative effect. When people are excited, excited, smoking, drinking, drinking strong tea or coffee, or in pathological conditions such as infection, fever, shock, anemia, hypoxia, hyperthyr...
