Abstract
An information processing device of the present invention includes: an image processing means that extracts a feature value of an object within a captured image obtained by capturing a pre-passing region of a gate, and stores matching information relating to matching of the object based on the feature value; a distance estimating means that estimates a distance from the gate to the object within the captured image; and a matching means that executes matching determination based on the estimated distance and the stored matching information of the object that the distance has been estimated.
Claims12
An information processing method performed by a computer and comprising:
- storing, in a first storage unit, a feature amount of a previously registered object;
- extracting respectively a feature amount of face regions of all persons appearing in an image capturing an area in front of a gate;
- tracking each person in a subsequent image;
- storing in a second storage unit, the extracted feature amount in association with the tracked each person;
- estimating a distance from the gate to each person;
- performing a matching process between the feature amount stored in the second storage unit and the feature amount stored in the first storage unit for any tracked person for which the estimated distance from the gate is within a predetermined distance;
- and
- opening the gate when the matching process indicates success for any tracked person for whom the estimated distance from the gate is within the predetermined distance.
An information processing device comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to execute the instructions to:
- store, in a first storage unit, a feature amount of a previously registered object;
- extract respectively a feature amount of face regions of all persons appearing in an image capturing an area in front of a gate;
- track each person in a subsequent image;
- store in a second storage unit, the extracted feature in association with the tracked each person;
- estimate a distance from the gate to each person;
- performing a matching process between the feature amount stored in the second storage unit and the feature amount stored in the first storage unit for any tracked person for which the estimated distance from the gate is within a predetermined distance;
- and
- open the gate when the matching process indicates success for any tracked person for whom the estimated distance from the gate is within the predetermined distance.
A non-transitory computer-readable medium storing a program comprising instructions for causing a computer to execute processing to:
- store, in a first storage unit, a feature amount of a previously registered object;
- extract respectively a feature amount of face regions of all persons appearing in an image capturing an area in front of a gate;
- track each person in a subsequent image;
- store in a second storage unit, the extracted feature in association with the tracked each person;
- estimate a distance from the gate to each person;
- performing a matching process between the feature amount stored in the second storage unit and the feature amount stored in the first storage unit for any tracked person for which the estimated distance from the gate is within a predetermined distance;
- and
- open the gate when the matching process indicates success for any tracked person for whom the estimated distance from the gate is within the predetermined distance.
