Abstract
A driving assistance apparatus has: an acquiring section that acquires an infrared image capturing an image capturing area including a driver's seat of a vehicle; a determining section that determines whether a flared highlight has occurred in the infrared image in a case where it is not possible to recognize the driver in the infrared image, on the basis of whether a pixel value of a pixel of a portion capturing an image of an area which is in the image capturing area in the infrared image and is hit by sunlight is equal to or greater than a predetermined value; and a setting section that makes waiting time longer than reference time, the waiting time being a time point at which a warning is given in a case where it is determined that the flared highlight has occurred in the infrared image.
Claims13
A driving assistance apparatus comprising:
- an acquiring section that acquires an infrared image captured while a first area including a driver's seat where a driver of a vehicle is seated is irradiated with an infrared ray;
- a determining section that determines whether or not a flared highlight has occurred in the infrared image in a case where it is not possible to recognize the driver in the infrared image, on a basis of whether or not a pixel value of a pixel of a determination portion capturing an image of a second area which is in the first area in the infrared image and is hit by sunlight is equal to or greater than a predetermined value;
- and
- a setting section that makes waiting time longer than reference time, the waiting time being time between a time point at which it has become not possible to recognize the driver in the infrared image and a time point at which a warning is given in a case where it is determined that the flared highlight has occurred in the infrared image.
A driving assistance method executed by a computer of a vehicle, the driving assistance method comprising:
- acquiring an infrared image captured while a first area including a driver's seat where a driver of the vehicle is seated is irradiated with an infrared ray;
- determining whether or not a flared highlight has occurred in the infrared image in a case where it is not possible to recognize the driver in the infrared image, on a basis of whether or not a pixel value of a pixel of a determination portion capturing an image of a second area which is in the first area in the infrared image and is hit by sunlight is equal to or greater than a predetermined value;
- and
- making waiting time longer than reference time, the waiting time being time between a time point at which it has become not possible to recognize the driver in the infrared image and a time point at which a warning is given in a case where it is determined that the flared highlight has occurred in the infrared image.
