Traffic situation display method, traffic situation display system, in-vehicle device, and computer program
First Claim
1. A traffic situation display method for displaying a traffic situation in a traffic situation display system, the method comprising:
- transmitting image data obtained by imaging an imaging region including roads from a road-side device and imaging orientation information identifying the imaging orientation of the road-side device;
receiving image data of different imaging orientations and the imaging orientation information, in an in-vehicle device;
detecting an advancing orientation of a vehicle in which the in-vehicle device is mounted;
selecting an image to be displayed on the basis of the detected advancing orientation and the received imaging orientation information;
displaying, by the in-vehicle device, the selected the image;
storing, by the road-side device, corresponding information in which a pixel coordinate in the image and positional information of the imaging region are corresponded to each other;
transmitting, by the road-side device, the stored corresponding information;
receiving, by the in-vehicle device, the corresponding information;
acquiring, by the in-vehicle device, positional information of an own vehicle;
specifying, by the in-vehicle device, an own vehicle position on the image on the basis of the received corresponding information and the acquired positional information; and
displaying, by the in-vehicle device, the specified own vehicle position on the image.
