ビデオ信号出力をもつ圧力分布センサと触覚パターン処理

抄録

An imaging tactile sensor for the measurement of pressure distributions and a real-time tactile image processing system using the sensor are described.
The sensor has a 64×64 array of sensitive sites using pressure-conductive rubber and electrodes on PC board. The scanning circuit of the sensor realizes precise and high speed scanning, 16.7ms per one frame, using a FET at every site for switching. As the output of this sensor is a video signal, pressure distributions can be visualized by a monitor TV and can be recorded by a video tape recorder.
By connecting the sensor with a high speed image processor, tactile image processing has been realized. In this paper, showing some examples such as smoothing, contour, trace, and adaptation of tactile images, features of tactile image processing are definitely shown by comparing with visual image processing. This system is used as a developing system of tactile processing algorisms as well as for the measurement of pressure distributions of human body with beds or chairs in the field of human engineering.
In this paper, the structure of the sensor and the architacture of the system are described and experimantal results are shown.
