Provided are an image learning device (11) and an image learning method capable of learning distance estimation by using sparse actual distance data as ground truth data in distance estimation for an observation image (40).
An image learning device that acquires at least one observation image (40) obtained by imaging an observation target with an image sensor, calculates, for the observation image (40), an estimated distance to the observation target for each of a plurality of locations within an imaging range of the image sensor by using a distance estimation parameter, and updates the distance estimation parameter based on a difference between an actual distance obtained by measuring a distance to the observation target and the estimated distance for at least one location within the imaging range, and the like are used.
