摘要： The present invention discloses a posture estimation system including a range image camera for acquiring and outputting range image and an attitude estimation device connected via the network to the range image camera. The range image camera includes a range image sensor, a range image generator that extracts a region including foreground pixels from the input range image acquired from the range image sensor and generates a range image including the extracted area, a first posture estimator that estimates a first joint position from the range image, and a first communicator that transmits the range image and the estimated first joint position. The posture estimating device includes a second communicator that receives the range image from the range image camera and the first joint position, a range image receiver that receives the range image via the second communicator, a posture estimator that estimates recognizes a second joint position different from the first joint position based on the range image received by the range image receiving unit, and generates estimated posture information based on the first joint position and the second joint position, and an outputter that outputs the generated estimated attitude information, wherein the first communicator sends a range image used for extracting the second joint position to the network.

摘要： To accurately recognize observed objects.
An observed-object recognition system includes an observation region estimation portion, an existence region estimation portion, and an object recognition portion. The observation region estimation portion estimates an observation region that is relatively highly likely to be an observation point in at least one first-person image in a first-person video (a video based on the first-person perspective). Based on the observation region, the existence region estimation portion estimates an existence region that belongs to the first-person image and causes an observed object to exist. The object recognition portion recognizes an object in the estimated existence region of the first-person image.-

摘要： To be capable of efficiently transmitting appropriate information on the motion improvement to a person in motion. A motion evaluation system includes a sensor unit, an information processing device, and an information presentation device. The information processing device includes a communication device, a storage device, and an arithmetic device. The arithmetic device acquires motion data acquired by observing a user through the use of a sensor via the communication device, checks the motion data against information about the correctness of motions in the reference information, determines a state of motion of the user, specifies a motion in a state to be improved as an improvement, check the motion data after the motion corresponding to the improvement against information about busy levels of the user to specify a busy level of the user, and outputs, as improvement suggestion information about the improvement, information with different contents at each of multiple times to an information presentation device based on the improvement and a rule predetermined according to each situation of the busy level.
