摘要： According to an embodiment, a transformation matrix deriving device includes a first trajectory generator, a second trajectory generator, a trajectory matcher, and a deriver. The first trajectory generator is configured to generate a first trajectory of a moving object, detected from a video, in a first coordinate system. The second trajectory generator is configured to generate a second trajectory of a moving object in a second coordinate system, from time-series data of positional information. The trajectory matcher is configured to associate the first trajectory with the second trajectory to be a motion trajectory of the same moving object based on a similarity between the first trajectory and the second trajectory. The deriver is configured to derive a transformation matrix that transforms the second coordinate system into the first coordinate system by using the first trajectory and the second trajectory associated with each other.

摘要： A recognition device includes an acquisition unit and a processor. The acquisition unit acquires first and second informations. The first information relates to a first signal corresponding to a state of a first portion of a body performing an action. The first signal is generated by a first element mounted to the first portion. The second information relates to a second signal corresponding to a state of a second portion. The second signal is generated by a second element mounted to the second portion. A relative positional relationship between the first portion and the second portion changes according to the action. The processor calculates a first feature based on the first information and a second feature based on the second information. The processor recognizes a type of the action based on a change of the first feature and a change of the second feature.
