1. A method for determining picture switching, comprising:
issuing tracking tasks for a target object to designated multiple monitoring devices;
receiving detection events reported by the monitoring devices, wherein the detection events are event information reported by the monitoring devices based on presence statuses of the target object in acquired video pictures, and when the presence statuses of the target object in acquired video pictures are different, the detection events reported by the monitoring devices are different, and event types of the detection events comprise a non-end tracking event and an end tracking event;
determining to perform cross-device tracking picture switching when a received detection event satisfies a preset condition for an object crossing an acquisition area; wherein, the object crossing the acquisition area means that the target object enters or leaves the acquisition area of one of the multiple monitoring devices.
