A device may obtain raw heartbeat data associated with a plurality of wavelength channels. The device may generate, based on a feature vector transformation, a plurality of feature vectors, each corresponding to a respective one of the plurality of wavelength channels. The device may identify a set of selected feature vectors, from the plurality of feature vectors, based on a plurality of squares of correlation coefficients, each associated with a respective pair of the plurality of feature vectors. The device may generate, based on a principal component analysis, an average feature vector of the set of selected feature vectors. The device may determine initial heartbeat cycle data based on the average feature vector. The device may correct heartbeat cycle gaps in the initial heartbeat cycle data in order to determine final heartbeat cycle data.本申請公開了自主式全光譜生物測定監測。一種設備可以獲得與多個波長通道相關聯的原始心跳資料。該設備可以基於特徵向量變換來產生多個特徵向量，每個特徵向量對應於多個波長通道中的相應一個波長通道。該設備可以基於多個相關係數平方從多個特徵向量中識別一組選定特徵向量，每個相關係數平方與多個特徵向量中的相應對相關聯。該設備可以基於主成分分析來產生該一組選定特徵向量的平均特徵向量。該設備可以基於平均特徵向量來確定初始心跳循環資料。該設備可以校正在初始心跳循環資料中的心跳循環間隙，以便確定最終心跳循環資料。
