1. A computer-implemented method for three-dimensional object reconstruction using an array of tactile sensors, said method comprising: receiving sensory data from the array of tactile sensors with respect to contact with an object of arbitrary shape in a reference coordinate system; processing the sensory data using a neural network to estimate a coordinate for each contact point between the array of tactile sensors and the object; reconstructing a three-dimensional morphology of the object based on the sensory data processed using the neural network; and outputting the three-dimensional morphology of the object.
