1. A data extraction device that extracts an image for transmission from images obtained by capturing surroundings outside a vehicle with an imaging device mounted on the vehicle, each time the vehicle travels an extraction distance, the data extraction device comprising:
processing circuitry configured to
acquire an image obtained by capturing the surroundings outside the vehicle;
determine, as an object to be analyzed, an image captured at a position advanced by the extraction distance from a position at which a previously extracted image has been captured, and calculate an obstruction distance which indicates an actual distance from an imaging start position of the image having been determined as the object to be analyzed to a position of an obstruction included in the determined image;
output the calculated obstruction distance as a next extraction distance for obtaining a next image by capturing surroundings outside the vehicle with the imaging device mounted on the vehicle; and
extract the image that has been determined as the object to be analyzed.
