Embodiment 1

[0019] A video detection and comparison system, comprising:

[0020] (1) a data collection module, used to collect target video data and three-dimensional data in the target video object; said data collection module collects target video data including video content captured and uploaded by a user terminal and video data migrated from an existing database; said The 3D data in the target video object includes the 3D data obtained by the user through automatic stitching based on the point cloud or the 3D data directly obtained by the 3D scanning device; it mainly refers to the user's outdoor shooting video and the 3D data collected by himself are transmitted to the data center through the terminal. Acquisition module, the video information accurately records the time and geographical location of the user when shooting;

[0021] (2) Video fingerprint synthesis module, used to extract the DC image information of the target video data, and then pass Harris detection to obtain image...

Abstract

The invention belongs to the technical field of video comparison, and particularly relates to a video detection and comparison system, which comprises (1) a data acquisition module; (2) a video fingerprint synthesis module; (3) a first verification module; and (4) a verification module II. According to the invention, feature extraction is carried out on each key frame in the target video; the extracted image features of each key frame are directly taken as a target video fingerprint; satellite three-dimensional data and a user actual three-dimensional data reconstruction picture are introducedto construct a video scene live-action model to obtain a reconstructed video key frame; and the similarity between the target video and the reference video is determined through mutual verification of the obtained reconstructed video key frame and the key frame number distance data of the verification module I. The outdoor video comparison accuracy is further improved, repeated comparison of videos is reduced through comparison, and time is saved.

Description

technical field [0001] The invention relates to the technical field of video comparison, in particular to an environmental condition detection system. Background technique [0002] With the increase of short video platforms, video data is growing exponentially, and the mass of location shooting videos is also growing rapidly. How to manage these location video data management has become a very critical link. In particular, video detection technology is used to measure the similarity between two videos, so as to realize video management services such as video deduplication and piracy detection. [0003] At present, the commonly used video detection technology is to measure whether the two videos are similar by comparing the distance of the video fingerprints of the two videos; and the video fingerprint is specifically obtained by extracting the key frame features of the video key frames, and then through the dimensionality reduction algorithm. Dimensionality reduction is per...
