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 () and a plurality of markers () provided therein, and a plurality of imaging devices () for obtaining a marker image by photographing the behavior of the markers when an object () contacts the tactile face () of the transparent elastic body (). 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 () using the plurality of imaging devices () such that each imaging device () has an overlapped photograph region (), and a step of integrating the partial images obtained by each imaging device () such that the identical markers in the overlapped photograph region match.
