When from the operational scene of the instrument operational recognition device

摘要

PROBLEM TO BE SOLVED: To recognize a tool used by a person with high accuracy from a movement scene wherein the person manually operates various tools, under a situation of presence of occlusion and discontinuity.;SOLUTION: An image input part 11 inputs a frame of the movement scene wherein the person operates the various tools, and an image storage part 12 stores the inputted frame. A velocity estimation part 13 estimates a velocity vector from the operation scene, and a symbol time series generation part 14 generates a symbol time series by a symbol conversion table 141 from the estimated velocity vector. A learning part 15 calculates an HMM model parameter by use of the generated symbol time series and performs learning. A recognition part 16 identifies the performed tool operation about the newly inputted movement scene by use of a learning result by the learning part 15 on the basis of the velocity vector estimated by the velocity estimation part 13, and an output part 17 outputs an identification result by the recognition part 16.;COPYRIGHT: (C)2005,JPO&NCIPI
