Claims (1)
- An information processing device installed in the first vehicle, To acquire a forward image, which is an image of the road extending in front of the second vehicle, captured by the front camera of the second vehicle traveling in front of the first vehicle, From the aforementioned forward image, detect obstacles present on the road, When the aforementioned obstacle is detected, the head-up display of the first vehicle superimposes a graphic of the second vehicle, partially transparent, with a graphic representing the obstacle. Based on the relative positions of the first vehicle and the second vehicle, the relative positions of the first vehicle and the third vehicle traveling behind the first vehicle, the speed of the first vehicle, the speed of the second vehicle, the speed of the third vehicle, the position of a vehicle traveling in the second lane adjacent to the first lane in which the first vehicle is traveling, and the speed of the vehicle traveling in the second lane, it is determined whether the first vehicle should change lanes from the first lane to the second lane in order to avoid the obstacle. When the first vehicle determines that it should change lanes from the first lane to the second lane, 前記ヘッドアップディスプレイ上において、前記第１の車両が前記障害物を避けるための支援情報 として、前記第１の車両が前記第２の車線に車線変更を行うための経路を示す線 を表示することと、 To notify the third vehicle of the location of the aforementioned obstacle, If it is determined that the first vehicle should not change lanes from the first lane to the second lane, The hazard lights of the first vehicle are turned on, and the brakes of the first vehicle are applied. To notify the third vehicle of the location of the aforementioned obstacle, An information processing device having a control unit that performs the following.
Description
This disclosure relates to driver assistance systems. Technologies for detecting obstacles and other objects in blind spots from the vehicle's perspective are known. In this regard, for example, Patent Document 1 discloses an in-vehicle device that receives images captured by a vehicle ahead via V2V (Vehicle-to-Vehicle) communication, detects fallen objects and other objects in blind spots from the vehicle's perspective based on the received images, and displays information related to those objects. Japanese Patent Publication No. 2021-043488 A diagram illustrating the components of an information processing device according to an embodiment.A flowchart of the processes executed by the control unit.An example of outputting images generated by the display unit to a HUD (Head-Up Display). An in-vehicle device is known that receives images from a front camera mounted on a vehicle traveling ahead, detects obstacles on the road in blind spots from the vehicle's perspective, and displays information about those obstacles. However, conventional in-vehicle devices do not prevent drivers from shifting their gaze from the driving position when checking information. When an in-vehicle device detects an obstacle or other object, it is preferable to display information about the obstacle or object on the display device in a manner that allows the driver to ensure safe driving. For example, when information is provided via a display device in a car navigation system, the driver needs to shift their gaze from the road ahead and focus on the display device. Thus, conventionally, there have been challenges in ensuring sufficient safety when checking information. The information processing device disclosed herein solves the aforementioned problems. An information processing device according to one aspect of this disclosure is characterized by having a control unit that performs the following actions: acquiring a forward image, which is an image of the road extending in front of the second vehicle, captured by a front camera of the second vehicle traveling in front of the first vehicle; detecting obstacles present on the road from the forward image; and, when an obstacle is detected, displaying a partially transparent graphic of the second vehicle and a graphic representing the obstacle superimposed on the head-up display of the first vehicle; and displaying support information on the head-up display for the first vehicle to avoid the obstacle. This configuration makes it possible to provide drivers with information about obstacles on the road without requiring them to shift their gaze, thereby enabling safer obstacle avoidance. (Embodiment) An overview of the information processing device according to the embodiment will be described with reference to Figure 1. The information processing device 100 is a device installed in the first vehicle 10 and the second vehicle 20. The second vehicle 20 is a vehicle that travels ahead of the first vehicle 10. The information processing device 100 mounted on the second vehicle 20 transmits the image captured by the front camera of the second vehicle 20 to the information processing device 100 mounted on the first vehicle 10 via wireless communication. The information processing device 100 mounted on the first vehicle 10 detects obstacles on the road from the acquired images and displays the detected obstacles on the head-up display (HUD) of the first vehicle 10. In addition, the information processing device 100 mounted on the first vehicle 10 also displays route guidance and other information on the HUD of the first vehicle 10 to help the first vehicle 10 avoid the obstacles. This allows the driver of the first vehicle 10 to obtain information about obstacles that are obstructed by the second vehicle 20. The information processing device 100 comprises a control unit 110, a communication unit 120, a storage unit 130, and a display 140. This section provides a detailed explanation of each component that makes up the system. First, let's explain the control unit 110. The control unit 110 is implemented using a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit) and memory. The control unit 110 includes, as functional modules, an acquisition unit 111, a detection unit 112, a display unit 113, a determination unit 114, an information transmission unit 115, and an image transmission unit 116. These functional modules may be implemented by executing a program via the control unit 110. The acquisition unit 111 acquires a forward image, which is an image of the road extending in front of the second vehicle 20, captured by the front camera of the second vehicle 20 traveling in front of the first vehicle 10. Here, the forward image may be video data or still image data. The acquisition unit 111 may also repeatedly acquire the forward image at predetermined time intervals. In this embodiment, the forward image is transmitted from the information processing device 1
