1. An optical tactile sensor comprising: a tactile section having a transparent elastic body and a plurality of markers provided therein; imaging means for obtaining a marker image by photographing behavior of markers when an object contacts the sensing surface of the transparent elastic body, wherein said imaging means comprises a plurality of imaging devices, and each of the plurality of imaging devices is provided such that each of the imaging regions which is captured using each of the respective imaging devices has an overlapped imaging region which partially overlaps; and said optical tactile sensor further comprising image integration means for integrating each of the marker images which are obtained using the plurality of imaging devices, wherein the image integration means integrates the imaging regions such that identical markers in the overlapped imaging regions are matched, to thereby form an integrated image.
