A 3D-object recognition device includes: a matching unit to compare a 3D-object in an image based on the image data with a 3D-shape model corresponding to the 3D-object to associate correlated feature points with each other by pattern matching; a model updating unit to update the 3D-shape model based on the feature points associated by the matching unit; a motion estimation unit to estimate motion of the 3D-object based on a history of the position and attitude of the 3D-shape model updated by the model updating unit to estimate a 3D-shape model at an arbitrary time in the future; and a validity determination unit to compare the feature points associated by the matching unit with the 3D-shape model estimated by the motion estimation unit and cause the model updating unit to update the 3D-shape model based on only the feature points determined to be valid.

Three-dimensional object recognition device and three-dimensional object recognition method

(A) One or both of an object and a robot are measured by measuring units to acquire sensor information. (B) The internal state of one or both of the object and the robot is predicted and updated by a state estimation unit on the basis of the sensor information. (C) The internal state is stored by a data storage unit. (D) The robot is controlled by a robot control unit. At (B), the internal state is updated by the state estimation unit at an arbitrary timing that is independent of the control cycle of the robot. At (D), a prediction value necessary for controlling the robot is calculated by the robot control unit at a control cycle on the basis of the latest internal state stored in the data storage unit.
