Abstract

A fixing-state determination system includes a glove an operator wears. A photographing device is placed at a position of the glove that corresponds to a portion between a pair of fingers which grip a target object, and photographs a target image. A position-and-posture estimation unit estimates a position and posture of the target object. A range calculation unit calculates a fingertip movement range which is a movement range of a fingertip of the operator. A contact position calculation unit calculates a contact position of the fingertip on the target object on a basis of the position and posture of the target object and the fingertip movement range. A determination unit determines a fixing state of the target object on a basis of displacement of the target object and excitation force information of an excitation force at the contact position of the fingertip for the target object.

Dependent claims

A fixing-state determination system which comprises a glove an operator wears to grip a target object and which determines a fixing state of the target object, the fixing-state determination system comprising:

a photographing device placed at a position of the glove that corresponds to a portion between a pair of fingers which grip the target object, to photograph the target object gripped by the pair of fingers as a target image;
and
processing circuitry
to estimate a position and posture of the target object by using the target image,
to analyze movement of a fingertip of the operator by using the target image, and to calculate a fingertip movement range which is a movement range of a position of a fingertip of each finger of the operator,
to calculate a contact position of the fingertip on the target object on a basis of the position and posture of the target object and the fingertip movement range, and
to determine the fixing state of the target object on a basis of displacement of the target object and excitation force information which is information of an excitation force at the contact position of the fingertip for the target object.

A glove provided to a fixing-state determination system which comprises the glove an operator wears to grip a target object, and an information processing device to communicate with the glove, the fixing-state determination system determining a fixing state of the target object,

the glove comprising:
a photographing device placed at a position corresponding to a portion between a pair of fingers which grip the target object, to photograph the target object gripped by the pair of fingers as a target image;
and
a communication device to transmit to the information processing device the target image, the information processing device estimating a position and posture of the target object by using the target image;
calculating a fingertip movement range which is a movement range of a position of a fingertip of each finger of the operator by using the target image;
and calculating a contact position of the fingertip on the target object on a basis of the position and posture of the target object and the fingertip movement range.
