Signal endpoint detection method, signal acquisition method and wearable device

The invention provides a signal endpoint detection method, a signal acquisition method, wearable equipment and a storage medium. The signal endpoint detection method comprises the following steps: acquiring a wrist movement signal of a user, wherein the wrist movement signal is a section of continuous signal generated when the wrist of the user moves; inputting the wrist motion signal into a pre-trained signal detection model to obtain a signal detection result, the signal detection result being a detection result for detecting whether each frame of signal in the wrist motion signal is a gesture signal; and determining an effective signal segment and a signal end point corresponding to the effective signal segment from the signal detection result based on a linear distance factor. Through the pre-trained signal detection model, the signal detection result can be quickly obtained, and the signal detection result is detected again through the linear distance factor, so that more accurate effective signal segmen
