ABSTRACT:
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.
