Problems solved by technology

[0003] However, there are more and more types of video cameras currently, and the product standards of each manufacturer are also different, which will lead to inconsistent capture time uploaded by the camera and multiple captures by the camera, which will make the availability of data worse.

Embodiment 1

[0058] In this embodiment, N front-end cameras are included, the time offset is 2S, the data is deduplicated within 30S, and the similarity is higher than 95%, it is considered to be the same data, and an example is given, such as figure 1 Shown:

[0059] First, when the capture camera is added to the system, a device record list will be added in the memory, which stores the normal device ID. After receiving the captured image after analysis, first judge the offset of the incoming data and the current Whether the time offset in the micro cloud server is within the acceptable range:

[0060] If it is within the acceptable range, judge whether the device ID is in the normal device list, if so, proceed to the next step, if not in the normal device list, add the device ID, and delete the data in the abnormal device list ;

[0061] If it is not within the threshold, then judge whether the device ID is in the abnormal device list, if it is in the abnormal device list, then proceed...

Abstract

The present invention provides a method, system, medium, and terminal for deduplication of characteristic data. The method includes: acquiring data to be processed of an access device, and judging the access time of the access device according to the access time and reference time of the data to be processed Device status, if it is determined to be a normal device, delete the overtime data based on the access time of the data to be processed; if it is determined to be an abnormal device, only delete the timeout data of the access device according to the device list; Compare the data characteristics of the data after deleting the timeout data, and complete the deduplication of the data; the present invention can greatly speed up the processing speed in the memory by storing the device and time in the form of a double-linked list; through the capture time and the offset of the server To determine whether the data is abnormal, and to ensure the stability of the system through the separate processing of abnormal equipment and normal equipment.

Description

technical field [0001] The present invention relates to the security field, in particular to a method, system, medium and terminal for deduplication of characteristic data. Background technique [0002] With the popularity of the Internet of Things, the application of smart devices is becoming more and more extensive, and smart monitoring devices such as smart cameras have become more and more common in daily life. In addition to real-time video recording, intelligent monitoring equipment can also capture pictures according to the scene. [0003] However, there are more and more types of video cameras currently, and the product standards of each manufacturer are also different, which will lead to inconsistent uploaded capture time of the camera and multiple captures by the camera, which will deteriorate the availability of data. Contents of the invention [0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a method, system,...
