Abstract
The illuminance estimation device is a device that estimates illuminance, which is the brightness around the vehicle. The illuminance estimation device acquires a forward image that is an image in front of the vehicle. The illuminance estimation device acquires the brightness of a road surface area, which is an area in which the road surface on which the vehicle travels, is shown in the forward image. The illuminance estimation device determines whether the vehicle will enter a structure into which the vehicle can enter, by analyzing the forward image. The illuminance estimation device obtains a value corresponding to the brightness of the road surface area as the illuminance when it is determined that the vehicle will enter the inside of the structure.
Claims5
An illuminance estimation device configured to estimate illuminance that is lightness around a vehicle, wherein the illuminance estimation device is configured to:
- acquire a forward image that is an image of an area ahead of the vehicle;
- acquire brightness of a road surface area that is an area where a road surface on which the vehicle travels is shown in the forward image;
- determine whether the vehicle is expected to enter a structure that the vehicle is allowed to enter by analyzing the forward image;
- and
- acquire a value corresponding to the brightness of the road surface area as the illuminance when determination is made that the vehicle is expected to enter the structure.
