Abstract
A visual recognition determination device for determining whether a driver has visually recognized an object detected by an external sensor of a vehicle is configured to perform estimating a sight-line vector of the driver using a driver monitoring camera of the vehicle, estimating a sight-line conical area which widens in a conical shape away from an eye point of the driver with respect to the sight-line vector of the driver, and determining whether the driver has visually recognized the object based on overlap of the sight-line conical area with the object.
