Description

Object determination method and device, storage medium and electronic device Technical Field The embodiment of the invention relates to the technical field of video monitoring, in particular to a method and a device for determining an object, a storage medium and an electronic device. Background Video monitoring technology has been widely used in many fields, for example, it can be used to monitor vehicles, personnel or alert areas, and video or image resources obtained by monitoring can be used to determine whether a vehicle is a problem vehicle causing an accident, or can be used to determine whether a child is a missing or a walking child reported by a parent, that is, can be used to determine whether a target object is an object of a specified type, and in the following description, it is determined whether a child is a walking child, and most towns currently have larger-scale video monitoring coverage, but the child is missing or is left endangered by the walking event. After the child is walked, the typical crutch seller will transfer the child to a different place at the fastest speed. If transferred successfully, it is difficult to find it out from the sea at the very large area. In the related technology, the photo of the missing child and related identity information are uploaded to a remote management center, the mobile client displays the photo of the missing child to a user in real time, the user can shoot a clue photo of the child suspected to be missing or being taken by the user through the mobile client, the photo is uploaded to the remote management center for matching, and after the matching is successful, the matching result is uploaded to a management system of a related department. As can be seen, the solution in the related art requires the user to actively upload the photograph of the suspected missing or the children being walked, and the management system is passive when determining whether a certain child is the children being walked, that is, passive when determining whether a certain object is an object of the target specified type, and cannot autonomously analyze whether the certain object is the object of the target specified type, so that the method for determining whether the object is the object of the specified type in the related art has a problem of low efficiency. For the problem of low determination efficiency of the object of the specified type existing in the related art, no effective solution has been proposed at present. Disclosure of Invention The embodiment of the invention provides a method and a device for determining an object, a storage medium and an electronic device, which are used for at least solving the problem that the determining efficiency of an object of a specified type in the related technology is low. According to one embodiment of the invention, an object determining method is provided, and the method comprises the steps of performing object detection on a current image frame to obtain a current detection result, determining whether a target file of a first object is included in a target platform or not under the condition that the current detection result comprises first information of the first object detected in the current image frame, wherein the first object is an object of a preset age range, the target file is a file obtained by performing file aggregation operation on information of the first object within a preset time period in the past, a first information set of the first object acquired within the preset time period is stored in the target file, and storing the first information into the target file under the condition that the target file is included in the target platform to obtain an updated file, wherein the updated file comprises a second information set of the first object, the second information set comprises the first information set and the first information, and whether the first object is a specified type of object is determined according to the updated file. In one exemplary embodiment, the determining whether the first object is an object of a specified type according to the updated archive includes determining a first duration of occurrence of the first object in a target area according to the updated archive, wherein the first information set is information of the first object obtained by object detection on a set of image frames, the set of image frames are image frames obtained by shooting the target area by a target image capturing device before the current image frame, and determining whether the first object is an object of a specified type if the first duration is greater than or equal to a predetermined duration threshold. In an exemplary embodiment, the determining the first time length when the first object appears in the target area according to the updated archive includes determining a difference between a first time and a second time as the first time length, where the first time is a shooting time of the
