Abstract:
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.
