Gesture recognition device and control method for the same
First Claim
1. A gesture recognition device configured to detect a gesture from an acquired image and generate a command issued to a control target instrument according to the gesture, the gesture recognition device being controlled by a processing unit or control target instrument to operate as:
- an image acquisition unit configured to acquire an image;
a gesture acquisition unit configured to detect a target region performing a gesture from the acquired image and acquire the gesture based on motion or a shape of the detected target region;
a face detection unit configured to detect a face comprised in the acquired image;
a correlation unit configured to correlate the detected target region with the detected face using a human body model representing a shape of a human body;
a personal identification unit configured to identify a user corresponding to the detected face;
a command generation unit configured to generate a command issued to the control target instrument based on the identified user and the acquired gesture; and
a gesture storage unit configured to store personal setting data, a set of a gesture and a command issued to the control target instrument being correlated with each user in the personal setting data;
wherein;
the command generation unit is configured to generate the command issued to the control target instrument based on the personal setting data;
the correlation unit is configured to calculate a range where the target region is estimated to exist for each detected face using a coordinate of the detected face and the human body model and correlate the target region and the face with each other when the target region exists in the calculated range; and
the personal identification unit is configured to identify the user through acquiring a user identifier corresponding to the face correlated with the target region by comparing feature amount of the correlated face with the personal setting data.
