The embodiment of the invention discloses a feature point detecting method and device, equipment and a storage medium. The method comprises the steps of obtaining periodical physiology signals of a testee, according to the physiology signals, determining the initial heart rate of the testee, and according to the initial heart rate, determining search parameters; based on a preset time sliding window detection strategy, detecting first limit valve points from the physiology signals, and if the first limit valve points are the neighbouring limit valve points in a search neighbouring region, determined by the first limit valve points and the search parameters, using the first limit valve points as second limit valve points; after the second limit valve points of a first preset number are obtained, according to the second limit valve points, calculating the target heart rate, and based on the target heart rate, determining the search parameter newly; and repeating the step for detecting the first limit valve points from the physiology signals based on the preset time sliding window detection strategy, until the physiology signal detection is complete, and according to the second limitvalve points, detecting feature points. According to the technical scheme of the embodiment of the invention, the effect of pinpoint detection of the feature point is achieved.
