Video analysis apparatus, monitoring system, and video analysis method
First Claim
1. A video analysis apparatus comprising:
- a memory that stores a program; and
a processor configured to run the program stored in the memory that is configured to cause the processor to;
determine a group including a difference frame having a data size equal to or larger than a predetermined threshold value among a plurality of groups for an encoded video data received from an imaging device capturing a monitored base, the group including a plurality of frames in a chronological order, the encoded video data being divided into the plurality of groups,perform a decoding process on the plurality of frames of the group determined to include the difference frame having the data size equal to or larger than the predetermined threshold value,perform a detecting process that detects a moving object by performing image analysis on the plurality of frames on which the decoding process has performed, anddetermine whether the group satisfies at least one of(a) including the difference frame having the data size equal to or larger than the predetermined threshold value,(b) an average value of the data size of the difference frame included in the group is equal to or larger than the predetermined threshold value, or(c) the difference frame having the data size equal to or larger than the predetermined threshold value and at least one other difference frame being continuous by a number that is equal to or larger than a predetermined number.

Abstract
A video analysis apparatus includes: 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.

12. A monitoring system for monitoring a monitored base, comprising:
-
a management server that receives encoded video data from an imaging device capturing a monitored base, and divides and manages the received video data in units of groups each including a plurality of frames in a chronological order, the encoded video data being divided into the plurality of groups; an identification server that determines a group including a difference frame having a data size equal to or larger than a predetermined threshold value among the plurality of groups for the encoded video data; an analysis server that performs a decoding process on the plurality of frames of the group determined to include the difference frame having the data size equal to or larger than the predetermined threshold value and performs image analysis on the decoded frames 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, wherein the identification server identifies whether the group satisfies at least one of (a) including the difference frame having the data size equal to or larger than the predetermined threshold value, (b) an average value of the data size of the difference frame included in the group is equal to or larger than the predetermined threshold value, or (c) the difference frame having the data size equal to or larger than the predetermined threshold value and at least one other difference frame being continuous by a number that is equal to or larger than a predetermined number. - View Dependent Claims (13, 14, 15, 16)

17. A video analysis method comprising:
-
determining a group including a difference frame having the data size equal to or larger than the predetermined threshold value among a plurality of groups for an encoded video data received from an imaging device capturing a monitored base, the group including a plurality of frames in a chronological order, the encoded video data being divided into the plurality of groups; performing a decoding process on the plurality of frames of the group determined to include the difference frame having the data size equal to or larger than the predetermined threshold value; detecting a moving object by performing image analysis on the plurality of frames on which the decoding process has performed; and identifying whether the group satisfies at least one of (a) including the difference frame having the data size equal to or larger than the predetermined threshold value, (b) an average value of the data size of the difference frame included in the group is equal to or larger than the predetermined threshold value, or (c) the difference frame having the data size equal to or larger than the predetermined threshold value and at least one other difference frame being continuous by a number that is equal to or larger than a predetermined number.
