Computer system, method, and program

A method comprising:

• performing fusion of first frame data and second frame data, the first frame data being generated at a first interval by a first sensor through space sensing, the second frame data including a plurality of pieces of subframe data each generated at an interval shorter than the first interval by a second sensor through the space sensing, the second frame data as a whole being generated at a second interval longer than the first interval;
• generating an optical flow between a reference time for at least one subframe data included in the second frame data and a reference time for the first frame data on a basis of a result of the space sensing by a third sensor of which temporal resolution is higher than that of the first sensor and that of the second sensor;
• and
• compensating a position of a sensing result included in the second frame data on a basis of the optical flow,
• wherein performing the fusion includes fusing the first frame data with the second frame data in which the position of the sensing result is compensated.

A non-transitory computer-readable medium storing computer-readable instructions that, when executed by a computer, cause the computer to perform operations comprising:

• performing fusion of first frame data and second frame data, the first frame data being generated at a first interval by a first sensor through space sensing, the second frame data including a plurality of pieces of subframe data each generated at an interval shorter than the first interval by a second sensor through the space sensing, the second frame data as a whole being generated at a second interval longer than the first interval;

• and
• compensating a position of a sensing result included in the second frame data on a basis of the optical flow,
