Classification: CPC G | IPC G

Claim 6:
7. A non-transitory computer-readable medium storing a moving body speed derivation program that causes at least one computer to execute a process, the process comprising:
acquiring moving image data including a plurality of time-series images captured from an imaging device installed in a first moving body;
recognizing a second moving body region included in the moving image data using a model to recognize a second moving body;
extracting a road region by applying semantic segmentation to the moving image data using a model to extract the road region;
deriving a reference point in the second moving body region in each image of the plurality of time-series images based on the road region and the second moving body region;
deriving a position of the second moving body in an actual space based on a distance between the imaging device and a feature point in the second moving body corresponding to the reference point and an absolute position of the first moving body acquired by using a global navigation satellite system; and
deriving a speed of the second moving body based on a change amount of the position of the second moving body in the actual space corresponding to the second moving body region included in the plurality of time-series images.
