Abstract: A blind spot in an observation area of a vehicle is estimated. Provided is a device for estimating a blind spot in an observation area of a vehicle that performs autonomous driving on the basis of data acquired by sensing the observation area. The blind spot estimation device includes an operation route generation unit that calculates an operation route of the vehicle, an observation area switching position calculation unit that calculates an observation area switching position at which the observation area is switched from a first observation area to a second observation area when the operation route intersects with a travel route of another moving body, an observation area calculation unit that calculates the second observation area, a scenario generation unit that generates a plurality of evaluation scenarios that are different in environmental condition for the operation route, a recognition determination unit that determines a success or failure of recognition of the other moving body in the second observation area by simulating a sensing of the second observation area by a sensor mounted to the vehicle according to the respective evaluation scenarios, and a risk map generation unit that aggregates results of the success or failure of recognition for the plurality of evaluation scenarios and generates a risk map indicating a blind spot in the second observation area superimposed on the second observation area.
