An authentication system () is provided with: an acquiring means () for acquiring a face image of a target () passing a gate (); a face authentication means () for performing a face authentication, in which it is determined that whether or not the target is a registered target, by collating information obtained from the face image of the target with information about faces of a plurality of registered targets; and a determining means () for determining whether or not the target can pass through the gate on the basis of a number of times of successful authentication when the face authentication is performed a plurality of times. According to such the authentication system, it is possible to properly determine that whether or not a target can pass a gate.

Authentication system, authentication apparatus, authentication method and computer program

A gate device is provided which prevents unauthenticated users from passing. The gate device is provided with an acquisition unit, an authentication request unit, a determination unit and a gate control unit. The acquisition unit acquires biological information of a person to be authenticated who is in an authentication area. The authentication request unit transmits to a server device an authentication request that contains the acquired biological information. The determination unit detects a person approaching the local gate device by using a sensor for detecting approaching persons, and determines whether or not the approaching person and the person to be authenticated are the same person. If authentication by the server device is successful and the approaching person and the authenticated person are the same person, then the gate control unit controls the gate to allow passage of the authenticated person.

A picking apparatus in an embodiment includes: a gripper, an arm, a detector, and a control unit. The gripper picks and grips an object to be conveyed. The arm moves the gripper and causes the gripper to convey the object to be conveyed. The detector is attached to the arm and senses a force applied to the gripper. The control unit controls an operation of the gripper and the arm. The control unit includes a calculator and a subtractor. The calculator calculates a gravitational force and an inertial force applied to the gripper when the gripper grips and moves the object to be conveyed using an arithmetic expression including a coefficient determined in accordance with a mass of the object to be conveyed. The subtractor subtracts the gravitational force and the inertial force calculated by the calculator from a force applied to the gripper sensed by the detector.
