Human skin aging assessment method and device and medium

The invention discloses a human skin aging assessment method and device and a medium, and relates to the field of ultrasonic signal processing, and the method comprises the steps: employing Hilbert transform to demodulate a high-frequency skin radio frequency signal to obtain an initial skin envelope signal; screening the initial skin envelope signal based on a preset region of interest to obtain a to-be-used skin envelope signal; inputting the to-be-used skin envelope signal and the corresponding projection signal into a preset adaptive envelope statistical model to obtain related characteristic parameters; the preset adaptive envelope statistical model is determined based on a preset signal decomposition algorithm and an envelope statistical algorithm; and inputting the adaptive shape parameters into corresponding linear functions to obtain a first skin age, a second skin age and a third skin age, and then evaluating the skin aging condition of the to-be-tested person in combination with the actual age of t
