Information processing device, information processing method, and information processing system

An information processing system, comprising:

• a computer including a memory and a processor configured to
• obtain first point group information that represents three-dimensional positional information, by using image data captured by a camera;
• output second point group information obtained by reducing noise of the first point group information, by using one or more filters;
• obtain third point group information that represents the three-dimensional positional information obtained by a position sensor;
• and
• train a filter coefficient estimation model by using test data for learning that includes the image data and training data based on the third point group information, so as to output filter coefficients of the one or more filters with which a difference between the second point group information and the training data is less than or equal to a threshold value.

An information processing method executed by a computer including a memory and a processor, the information processing method comprising:

• obtaining first point group information that represents three-dimensional positional information, by using image data captured by a first camera;
• outputting second point group information obtained by reducing noise of the first point group information, by using one or more filters;
• and
• setting filter coefficients of the one or more filters, by using (i) a filter coefficient estimation model trained in advance by using (a) test data for learning that includes image data captured by a second camera and (b) training data based on third point group information that represents three-dimensional positional information obtained by a position sensor, and (ii) observation data that includes the image data captured by the first camera.
