Description

This disclosure relates to an information processing system, and more particularly to an information processing system capable of accurately determining the location of a user. Patent Document 1 discloses a method for determining the position of a pedestrian using a camera and radar mounted on a vehicle. Japanese Patent Publication No. 2023-116424 A diagram illustrating the overview of the information processing system according to the embodiment.A diagram showing the configuration of the information processing device and vehicle in the embodiment.A flowchart showing the processing flow performed by the information processing device in the embodiment.This diagram illustrates an example of the process for determining whether the sensing target is the target user.A diagram illustrating another example of the process for determining whether the sensing target is the target user. (overview) If a user's location can be accurately determined, that location information can be used more effectively. For example, ride-hailing services may need to consider which side of the road the user is on when moving their vehicle. In such cases, location detection with a precision finer than the road width is required, but GPS devices may not be able to provide sufficient precision. Incidentally, recent 5G communications utilize terahertz waves. Furthermore, object detection using terahertz waves with 5G communication equipment has been proposed. In this disclosure, this type of sensing is also referred to as 5G sensing. By using 5G sensing, highly accurate position detection is possible. One aspect of this disclosure is an information processing system comprising a plurality of mobile bodies and an information processing device. The mobile bodies are typically vehicles (including electric vehicles, hybrid vehicles, and gasoline vehicles), but may also be flying objects or other mobile bodies. The mobile bodies are equipped with communication devices capable of communication using terahertz waves. This communication device is a device capable of sensing using terahertz waves, and may, for example, be a 5G or next-generation mobile communication device, but may also be a terahertz wave radar device. The information processing device performs the following actions: transmits a sensing request to the first mobile object, receives sensing results from the first mobile object including the detection location of the detected object, and, if the sensing results indicate the detection of a predetermined user, notifies the second mobile object of information related to the location of the predetermined user. The sensing results include information on at least one of the following: the position, shape, or type of the sensed object, or sensing data that allows for the calculation of such information. In other words, the determination of the object's position, shape, type, etc., based on the sensing data may be performed by a moving object, an information processing device, or other device. Information related to the user's location may be the user's location itself, or any information obtained based on the user's location. An example of information obtained based on the user's location is the route taken to reach the user's location. This disclosure can be used in a service that dispatches a mobile body to a user's location. For example, the control unit of an information processing device may acquire first location information representing the location of a predetermined user, select a mobile body to be moved to the predetermined user's location as the second mobile body, acquire second location information which is the location of the predetermined user with higher accuracy than the first location information based on the sensing results of the first mobile body, search for a path from the current location of the second mobile body to the location indicated by the second location information, taking into account which side of the road the second location information faces, and notify the second mobile body of the searched path. In this way, the second mobile body can be directed to the location of the user. Since the side of the road it is located on is taken into consideration, the user's access to the second mobile body (such as boarding or receiving goods) becomes easier. Note that the sensing request for the first mobile body from the information processing device only needs to be made when the second mobile body is located within a predetermined range from the first location information. This is because the user's detailed location only needs to be known when the second mobile body has reached a certain distance from the user. In this disclosure, the determination of whether the sensing result is the result of detecting a predetermined user may be performed by a mobile device, an information processing device, or another device. For example, the information processing device may make the determination as follows: In this disclosure
