Judgment device, judgment method, and computer program

Abstract

To enable the detection of forgotten items inside the vehicle with greater accuracy, before passengers have completely disembarked. [Solution] A determination device comprising: a determination unit that detects an object in an in-vehicle image, which is an image of the inside of a vehicle to be determined, determines whether or not a person inside the vehicle has disembarked, and determines that there is a lost item if an object is detected at a position more than a predetermined distance away from the person and the person has disembarked; and an information control unit that outputs a predetermined output from an output unit when the determination unit determines that there is a lost item.

Claims

1. A determination unit detects an object in an in-vehicle image, which is an image of the inside of the vehicle to be determined, determines whether or not a person inside the vehicle has disembarked, and determines that there is a lost item if an object is detected at a distance greater than a predetermined distance from the person and the person has disembarked. If the determination unit determines that an item has been left behind, the information control unit outputs a predetermined output from the output unit, A determination device equipped with the following features.

2. The determination device according to claim 1, wherein the determination unit determines whether or not a person inside the vehicle to be determined is in a state of disembarking, using a trained model obtained by performing a learning process using images of a person in a disembarking state as training images.

3. The determination device according to claim 1, wherein the determination unit determines whether or not the person inside the vehicle being determined is in a disembarked state based on the area of ​​the region detected as a part of the person's body.

4. A determination step in which an object is detected in an in-vehicle image, which is an image of the inside of the vehicle to be judged, and it is determined whether or not a person inside the vehicle has disembarked, and if an object is detected at a distance greater than a predetermined distance from the person and the person has disembarked, it is determined that there is a lost item. If it is determined in the aforementioned determination step that an item has been left behind, an information control step is performed in which the output unit outputs a predetermined output, A method for determining the thumbnail.

5. A determination unit detects an object in an in-vehicle image, which is an image of the inside of the vehicle to be determined, determines whether or not a person inside the vehicle has disembarked, and determines that there is a lost item if an object is detected at a distance greater than a predetermined distance from the person and the person has disembarked. A computer program for causing a computer to function as a determination device comprising an information control unit that outputs a predetermined output from an output unit when the determination unit determines that an item has been left behind.
