First Claim
Patent Images
1. A gaze point detection device comprising:
- a processor; and
a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute,capturing an image of at least part of a scene around a vehicle;
detecting a direction of a line of sight of a person in the vehicle;
determining an intersection between a plane and a line of sight of the person in the vehicle, the plane being along a running direction of the vehicle and apart from the vehicle by a given distance; and
projecting the intersection onto the image and presenting a resultant projected point on the image as a gaze point gazed at by the person in the vehicle.
