Abstract

There is provided an information processing apparatus, comprising: an obtaining unit which obtains video data captured by an image capturing apparatus disposed in a monitored space, location information regarding a location of a moving object in the monitored space, and existence information regarding a capturing period of the moving object in the video data; and a display processing unit which processes a display of a trajectory of the moving object in the monitored space based on the location information, the display processing unit processing a display of the trajectory so that the portion of the trajectory that corresponds to the capturing period is distinguishable from the other portions of the trajectory, based on the existence information.

Claims

1. An information processing apparatus, comprising:

an obtaining unit which obtains video data captured by an image capturing apparatus disposed in a monitored space, location information regarding a location of a moving object in the monitored space, and existence information regarding a capturing period of the moving object in the video data; and

a display processing unit which processes a display of a trajectory of the moving object in the monitored space based on the location information, the display processing unit processing a display of the trajectory so that the portion of the trajectory that corresponds to the capturing period is distinguishable from the other portions of the trajectory, based on the existence information.

2. The information processing apparatus according to claim 1, further comprising:

a moving object selection unit which selects a moving object,

wherein the display processing unit processes a display of only the trajectory of the moving object selected by the moving object selection unit.

3. The information processing apparatus according to claim 1, further comprising:

a first selection unit which selects a capturing period in the trajectory,

wherein the display processing unit reproduces a portion of the video data that corresponds to the capturing period selected by the first selection unit.

4. The information processing apparatus according to claim 3, wherein the display processing unit processes a display of a pointer indicating a location of the moving object in the trajectory at the time at which the video data is captured.

5. The information processing apparatus according to claim 4, further comprising:

a pointer movement unit which moves the pointer along the trajectory,

wherein the display processing unit reproduces a portion of the video data captured at the time at which the moving object was present in a location in the monitored space that corresponds to a location indicated by the pointer moved by the pointer movement unit.

6. The information processing apparatus according to claim 1, wherein the display processing unit processes a display of the trajectory so that the image capturing apparatus which captured the capturing period can be identified.

7. The information processing apparatus according to claim 1, wherein:

the display processing unit processes a display of a capturing period of the moving object on a time axis, based on the existence information, and

the display processing unit reproduces a portion of the video data that corresponds to the capturing period selected in the time axis.

8. The information processing apparatus according to claim 7, wherein the display processing unit processes a display of the capturing period on the time axis so that moving objects can be distinguished from one another and so that the image capturing apparatus which captured the capturing period can be identified.

9. The information processing apparatus according to claim 3, further comprising:

an extraction unit which extracts a representative video frame at a predetermined interval from a portion of the video data that corresponds to the capturing period selected by the first selection unit,

wherein the display processing unit processes a display of an image based on the representative video frame in association with a location of the moving object in the trajectory at the time when the representative video frame is captured.

10. The information processing apparatus according to claim 9, wherein

the display processing unit processes a display of an outgoing line connecting the image based on the representative video frame to the location of the moving object in the trajectory at the time when the representative video frame is captured, and

the display processing unit processes a display of the images based on the representative video frame so as not to overlap with one another.

11. An information processing method, comprising the steps of:

obtaining video data captured by an image capturing apparatus disposed in a monitored space, location information regarding a location of a moving object in the monitored space, and existence information regarding a capturing period of the moving object in the video data; and

displaying a trajectory of the moving object in the monitored space based on the location information, and displaying the trajectory so that the portion of the trajectory that corresponds to the capturing period is distinguishable from the other portions of the trajectory, based on the existence information.

12. The information processing method according to claim 11, further comprising the steps of:

selecting a capturing period in the trajectory; and

reproducing a portion of the video data that corresponds to the capturing period selected in the step of selecting.

13. A computer-readable storage medium storing a computer program causing a computer to perform an information processing method comprising the steps of:

obtaining video data captured by an image capturing apparatus disposed in a monitored space, location information regarding a location of a moving object in the monitored space, and existence information regarding a capturing period of the moving object in the video data; and

displaying a trajectory of the moving object in the monitored space based on the location information, and displaying the trajectory so that the portion of the trajectory that corresponds to the capturing period is distinguishable from the other portions of the trajectory, based on the existence information.
