Abstract

Position information on every moving object is acquired from a moving image of a monitoring area, and activity information during every unit time is acquired from the position information on every moving object. Conditions of an observation period of time are set according to a user input operation, the observation period of time is controlled in accordance with the conditions of the observation period of time, and the activity information during every unit time is aggregated during the observation period of time to acquire the activity information during the observation period of time. An activity map image is generated from the activity information during the observation period of time, and the activity map image and the moving image of the monitoring area are generated and output at every predetermined point in time.

First claim

What is claimed is:

1 . An activity situation analysis apparatus that observes an activity situation of a moving object in a monitoring area, generates an activity map image that results from visualizing the activity situation of the moving object based on a result of the observation, and displays the generated activity map image on a display device, the activity situation analysis apparatus comprising:
a processor; a memory in which an instruction is stored; a position information acquirer that detects the moving object from a moving image of the monitoring area and acquires position information on every moving object; an activity information acquirer that acquires activity information based on the position information on every moving object; an observation condition setter that sets conditions relating to an observation period of time for observing activity situation of the moving object according to a user input operation; an observation-period-of-time controller that controls the observation period of time in accordance with the conditions relating to the observation period of time that is set by the observation condition setter; an activity information aggregator that aggregates the activity information based on the observation period of time that is controlled by the observation-period-of-time controller, and acquires the activity information during the observation period of time; an activity map image generator that generates the activity map image based on the activity information during the observation period of time; and an output controller that generates a monitoring moving image including the activity map image and the moving image of the monitoring area at every predetermined point in time, and outputs the generated monitoring moving image to the display device, wherein the position information acquirer, the activity information acquirer, the observation condition setter, the observation-period-of-time controller, the activity information aggregator, the activity map image generator, and the output controller are configured to execute the instruction of the processor.

2 . The activity situation analysis apparatus of claim 1 ,
wherein the output controller generates the monitoring moving image that results from superimposing the activity map image onto the moving image of the monitoring area, and outputs the generated monitoring moving image.

3 . The activity situation analysis apparatus of claim 1 ,
wherein the observation-period-of-time controller controls the observation period of time in such a manner that, according to progress of a display point in time of the moving image of the monitoring area, the observation period of time moves following the display point in time.

4 . The activity situation analysis apparatus of claim 3 ,
wherein the observation-period-of-time controller controls the observation period of time in such a manner that, based on a setting length of the observation period of time that is set by the observation condition setter, a period of time that is by the setting length of the observation period of time earlier than the display point in time of the moving image of the monitoring area is the observation period of time.

5 . The activity situation analysis apparatus of claim 4 ,
wherein the observation-period-of-time controller controls the observation period of time in such a manner that a period of time from a display starting point in time to the display point in time is the observation period of time until an elapsed period of time from the display starting point in time of the moving image of the monitoring area to the display point in time reaches the setting length of the observation period of time.

6 . The activity situation analysis apparatus of claim 1 ,
wherein the observation-period-of-time controller controls the observation period of time in such a manner that, based on a setting range of the observation period of time, which is set by the observation condition setter, within the setting range of the observation period of time, a period of time from the display starting point in time of the moving image of the monitoring area, which is a starting point of the observation period of time, to a display point in time is the observation period of time.

7 . The activity situation analysis apparatus of claim 1 ,
wherein the observation condition setter sets a length of or a range of the observation period of time according to the user input operation that arbitrarily designates the length of or the range of the observation period of time as conditions of the observation period of time.

8 . The activity situation analysis apparatus of claim 1 ,
wherein the output controller generates the monitoring moving image including the activity map image and a current moving image of the monitoring area in real time, and outputs the generated monitoring moving image.

9 . The activity situation analysis apparatus of claim 1 further comprising:
a unit time setter that sets a unit time relating to the acquisition of the activity information according to a user input operation,
wherein the activity information acquirer acquires the activity information on every unit time based on the unit time that is set by the unit time setter.

10 . The activity situation analysis apparatus of claim 1 ,
wherein the activity information includes information relating to at least either of the number of stays that is the number of moving objects that stay in an observation area that is set to be within the monitoring area and a staying time that is a time for which the moving object stays within the observation area.

11 . An activity situation analysis system that observes an activity situation of a moving object in a monitoring area, generates an activity map image that results from visualizing the activity situation of the moving object based on a result of the observation, and displays the generated activity map image on a display device,
the activity situation analysis system comprising: a camera that captures a moving image of the monitoring area; and multiple information processing apparatuses, wherein any one of the multiple information processing apparatuses includes a processor, a memory in which an instruction is stored, a position information acquirer that detects the moving object from the moving image of the monitoring area and acquires position information on every moving object, an activity information acquirer that acquires activity information based on the position information on every moving object, an observation condition setter that sets conditions relating to an observation period of time for observing activity situation of the moving object according to a user input operation, an observation-period-of-time controller that controls the observation period of time in accordance with the conditions of the observation period of time that is set by the observation condition setter, an activity information aggregator that aggregates the activity information based on the observation period of time that is controlled by the observation-period-of-time controller, and acquires the activity information during the observation period of time, an activity map image generator that generates the activity map image based on the activity information during the observation period of time, and an output controller that generates a monitoring moving image including the activity map image and the moving image of the monitoring area at every predetermined point in time, and outputs the generated monitoring moving image to the display device, and wherein the position information acquirer, the activity information acquirer, th
