  • Publication number: 20230368408
    Abstract: A position estimator outputs, by inputting information obtained from the frame images into a trained model, positional information of a plurality of parts of a human body from the trained model. A determination processor outputs information on erroneous detection by the position estimator. The position estimator outputs a first position group in response to an input of an obtained first frame image, the first frame image being obtained by the receiver and outputs a second position group in response to an input of an obtained second frame image different from the first frame image, the second frame image being obtained by the receiver. The determination processor outputs the information on erroneous detection by the position estimator based on a degree of difference between the first position group and the second position group and a degree of matching between the first frame image and the second frame image.
