Abstract
The present application discloses active/inactive state detection methods, where the method is performed by a monitoring and detecting system, and includes the following: monitoring a distance between an object and a target object within a distance detection range; when the distance between the object and the target object satisfies a first predetermined condition, sending a first instruction to an image acquisition system corresponding to the distance detection range, so as to activate the image acquisition system to obtain an image in an image acquisition area of the image acquisition system; and determining a state of the target object based on a recognition result obtained by performing object recognition on the image in the image acquisition area, where the state of the target object includes an active state and/or an inactive state. In the implementations of the present application, whether a predetermined object is active and/or inactive can be accurately determined, system power consumption can be effectively reduced, and application needs can be satisfied.
