Gaze point detection device and gaze point detection method

摘要

A gaze point detection device includes 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 presenting a resultant projected point on the image as a gaze point.

1. A gaze point detection device comprising:
an image processor; and a memory which stores a plurality of instructions, which when executed by the image processor, cause the image processor to execute, an outside-of-vehicle image capturing unit to capture 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 based on an inside-of-vehicle image taken by an inside-of-vehicle image capturing unit; setting a line-of-sight projection plane in at least part of a region around the vehicle such that the plane is along the running direction of the vehicle and apart from the vehicle by the distance where there is a possibility that there is an object gazed at by the person in the vehicle; determining an intersection between the plane and a line of sight of the person in the vehicle; projecting the intersection onto the outside-of-vehicle image and presenting a resultant projected point on the outside-of-vehicle image as a gaze point gazed at by the person in the vehicle; and detecting the object to be gazed at on the outside-of-vehicle image by the person.
