VIDEO ANALYSIS APPARATUS, MONITORING SYSTEM, AND VIDEO ANALYSIS METHOD
First Claim
1. A video analysis apparatus comprising:
- an identification unit that identifies whether each divided group includes a difference frame with a data size of a predetermined threshold value or more, the group being configured from video data which is encoded video data received from an imaging device captured a monitored base and is divided in units of groups each including a plurality of frames in a chronological order;
a decoding unit that performs a decoding process on the plurality of frames of the group identified by the identification unit to include the difference frame with the data size of the predetermined threshold value or more; and
a detection unit that performs image analysis on the decoded each frame to detect a moving object.

13. A monitoring system for monitoring a monitored base, comprising:
-
a management server that receives decoded video data from an imaging device captured the monitored base, and divides and manages the received video data in units of groups each including a plurality of frames in a chronological order; an identification server that identifies whether each divided group includes a difference frame with a data size of a predetermined threshold value or more, the group being configured from the divided video data; an analysis server that performs a decoding process on the plurality of frames of the group identified by the identification server to include the difference frame with the data size of the predetermined threshold value or more and performs image analysis on the decoded each frame to detect a moving object; and a monitoring terminal including a display unit that displays information representing that a moving object has been detected according to an instruction from the management server when the analysis server has detected the moving object. - View Dependent Claims (14, 15, 16, 17, 18)
