摘要： Provided are a human recognition apparatus and a human recognition method identifying a user based on a walking pattern. The human recognition apparatus includes a detecting unit detecting a vibration according to a user's walking, and outputting an electric signal, a pattern calculating unit acquiring a walker's walking pattern from the electric signal, and a user determining unit comparing the walking pattern with a previously measured reference data by user and identifying the user based on the comparison result. The human recognition apparatus and the human recognition method are robust against peripheral noise and can increase an acceptance rate through a simple structure and procedure by using the waling pattern, which is one-dimensional time information requiring no vast data throughput, as the user identification data.

摘要： The present invention relates to a mobile system and a moving method of the mobile system. According to the present invention, a natural period is measured from a vibration component signal generated by a force due to acceleration/deceleration of wheels, and the mobile system moves by applying an acceleration profile containing an acceleration period or a deceleration period based on the natural period. Therefore, the acceleration profile based on the natural period is applied such that vibration that is visible to a user is not generated during acceleration and deceleration of the mobile system. As a result, quality of the mobile system is improved.

摘要： Provided is a person detecting apparatus and method in an intelligent mobile robot. The person detecting apparatus includes a camera, an observation system status input unit, an encoding unit, a decoding unit, and a person detection unit. The camera is mounted on a robot to output image information. The observation system status input unit determines whether the robot or the camera is in motion.

The decoding unit decodes the bit stream, extracts a block mode value of each macro block, and stores the same in a two-dimensional array. The person detection unit outputs detection information about a moving person using the determination information provided from the observation system status input unit and the block-mode two-dimensional array provided from the decoding unit.
