Abstract

The invention relates to a method and system for determining the motion trajectory of a characteristic object in a distributed and parallel mode. The method includes the steps that based on a distributed framework, a massive amount of video acquired by video acquisition devices installed in different geographical positions are analyzed in parallel so as to recognize the characteristic target with the trajectory to be determined; based on time stamps in recognized video frames containing the characteristic target and the information of positions where the video acquisition devices for acquiring the corresponding video frames are located, the times when the characteristic target occurs in the geographical positions for acquisition are recognized in parallel, and the characteristic target is correlated with the occurrence times of the characteristic target and the geographical positions where the characteristic target occurs; based on the correlation between the occurrence times of the characteristic target and the geographical positions where the characteristic target occurs obtained through statistics, the geographical positions where the characteristic target occurs are sequentially connected according to the sequence of the occurrence times of the same characteristic target, and thus the motion trajectory of the same characteristic target is formed. Through the method and system for determining the motion trajectory of a characteristic object in the distributed and parallel mode, a complete motion trajectory of a characteristic target can be automatically formed.

Description

technical field [0001] The present disclosure relates to the field of cloud computing, and in particular, to a method and system for determining the trajectory of a characteristic target in parallel in a distributed manner. Background technique [0002] At present, all kinds of public monitoring systems have produced a large amount of video surveillance videos. How to quickly query the designated target in the massive video surveillance videos, and quickly understand the complete activity track of the target object, so far, the existing technology has not provided A perfect solution. [0003] When a user needs to obtain the activity of a certain target in 2,000Tbit video surveillance video, the current common solution is to analyze and return thousands of analysis result records or pictures to the user. The user is faced with these large-scale records or pictures, I can only look at so many "result data oceans" and sigh. Contents of the invention [0004] The present dis...
