    摘要: An optical tactile sensor and an image information integrating method capable of measuring large area force vector distribution are provided. The optical tactile sensor comprises a tactile section comprising a transparent elastic body (1) and a plurality of markers (3, 4) provided therein, and a plurality of imaging devices (6, 6) for obtaining a marker image by photographing the behavior of the markers when an object (5) contacts the tactile face (2) of the transparent elastic body (1). The method comprises a step of obtaining a partial image by photographing the partial regions A, B, C and D of the transparent resilient body (1) using the plurality of imaging devices (6, 6) such that each imaging device (6) has an overlapped photograph region (11), and a step of integrating the partial images obtained by each imaging device (6) such that the identical markers in the overlapped photograph region match.

    摘要: The invention relates to a technique for reducing computation time for force vector calculation. A force vector reconstruction method that uses an optical tactile sensor, comprises a step for obtaining a marker image by taking an image of behavior of colored markers when an object contacts a contact surface of an elastic body, a step of obtaining information relating to the marker behavior from the marker image, the information being more than the number of force vectors to be obtained, and a step of obtaining force vectors as outputs by inputting information relating to the obtained marker behavior to a transfer function. The step of obtaining force vectors comprises calculating force vectors using only information relating to behavior of markers neighboring region A1 of a position A where it is desired to obtain force vectors.
