Abstract
The present invention relates to a CPR posture monitoring model and system, the model being configured to: based on human skeleton point data extracted from CPR moves, at least compute arm-posture angle data and GC matching angle data related to the CPR moves, and determine whether the CPR moves are qualified by comparing arm-posture angle data and GC matching angle data to a CCP qualification threshold; wherein human skeleton point data are extracted from first move data collected by a first optical component and second move data collected by a second optical component simultaneously, wherein an included angle between collection directions of the two optical components ranges between 30 and 90 degrees. By constructing and applying a CPR posture monitoring model defined by data like GC matching angle, evaluation result has higher accuracy. Compared with the prior art where the equipment positions must be exactly the same as the equipment positions when the data are acquired for the AI algorithm to compute the CPR mistakes, the disclosed method does not require that the equipment positions must be exactly the same as the equipment positions when collecting the data and could tolerat…
