Abstract
An in-vehicle apparatus according to the present disclosure includes: estimated walking path acquisition means for acquiring an estimated walking path, which is a path in which it is estimated that a driver will walk; and drinking determination means for determining whether or not the driver is drunk based on a walking pattern of the driver in the estimated walking path.
Claims11
An in-vehicle apparatus comprising:
- an image-capturing device,
- at least one memory storing instructions, and
- at least one processor configured to execute the instructions to:
- detect current position coordinates of a driver;
- detect a shoulder width of the driver;
- detect at least one of a line-of-sight of the driver and an orientation of the body of the driver as a movement direction of the driver based on an image captured by the image-capturing device;
- set an estimated walking path, which is a path in which it is estimated that the driver will walk from the detected current position coordinates;
- set a width of the estimated walking path based on the detected shoulder width;
- and
- determine whether or not the driver is drunk based on a walking pattern of the driver with respect to the estimated walking path with the set width, wherein determining whether or not the driver is drunk further comprises:
- determining whether or not the movement direction of the driver has changed by more than a pre-determined threshold.

A drinking determination method comprising:
- detecting current position coordinates of a driver;
- detecting a shoulder width of the driver;
- detecting at least one of a line-of-sight of the driver and an orientation of the body of the driver as a movement direction of the driver based on an image captured by the image-capturing device;
- setting an estimated walking path, which is a path in which it is estimated that the driver will walk from the detected current position coordinates;
- setting a width of the estimated walking path based on the detected shoulder width;
- and
- determining whether or not the driver is drunk based on a walking pattern of the driver in the estimated walking path with the set width, wherein determining whether or not the driver is drunk further comprises:
- determining whether or not the movement direction of the driver has changed by more than a pre-determined threshold.
5 more elements
A non-transitory computer readable storage medium that stores a program for causing an electronic device including at least one processor to execute the following processing of:
- detecting current position coordinates of a driver;
- detecting a shoulder width of the driver;
- detecting at least one of a line-of-sight of the driver and an orientation of the body of the driver as a movement direction of the driver based on an image captured by the image-capturing device;
- setting an estimated walking path, which is a path in which it is estimated that the driver will walk from the detected current position coordinates;
- setting a width of the estimated walking path based on the detected shoulder width;
- and
- determining whether or not the driver is drunk based on a walking pattern of the driver in the estimated walking path with the set width, wherein determining whether or not the driver is drunk further comprises:
- determining whether or not the movement direction of the driver has changed by more than a pre-determined threshold.
