Human body target posture detection method and intelligent product control method

The invention relates to the field of human body posture detection, in particular to a human body target posture detection method and system and a control method of an intelligent product, and the method comprises the steps: transmitting a first detection signal through a first sensing assembly, and receiving a signal reflected by a human body target through a two-dimensional receiving sensing assembly, the signal processor processes the signal received by the two-dimensional receiving sensing assembly to obtain contour information of the human body target; a second sensing assembly is used for emitting a second detection signal, a two-dimensional receiving sensing assembly is used for receiving a signal reflected by the human body target, and a signal processor is used for processing the signal received by the two-dimensional receiving sensing assembly to obtain heart distance information and determining the position of the heart in the contour information according to the heart distance information; the sig
