Problems solved by technology

[0006] On the vehicle side, if the image data generated by the on-board camera is directly sent to the server, there is a problem that the amount of data sent to the server becomes huge
In addition, if a charging system in which the communication cost depends on the amount of data is adopted, there is also a problem that the communication cost increases with the huge amount of data.

Embodiment Construction

[0027] Hereinafter, an embodiment will be described with reference to the drawings. Such as figure 1 As shown, the trajectory data generating system 1 includes a vehicle image data generating device 2 mounted on a vehicle, and a server 3. The vehicle image data generating device 2 and the server 3 are configured to be capable of data communication via a communication network. The communication network is, for example, a wide area communication network.

[0028] Such as figure 2 As shown, the server 3 has, for example, image recognition for basic map data provided by the Japan Land Geographical Institute, aerial photo data taken by an aircraft from the sky, and navigation map data used for navigation, etc., to generate a map for automatic driving. Functions for driving track data. The server 3 has an image recognition unit 4, a lane network data generation unit 5 between intersections, a lane network data processing unit 6 between intersections, a lane network data generati...

Abstract

An image data generation device (2) for a vehicle, provided by the invention, performs data communication with a server (3). The server (3) performs image recognition with respect to base map data and / or aerial photographic data and / or navigation-use map data, performs image recognition with respect to image data generated by a vehicle-mounted camera (22), and generates travel trajectory data forautonomous driving. The image data generation device for a vehicle comprises: a segment image data generation unit (11) for generating, as segment image data, image data for each segment from the image data generated by the vehicle-mounted camera; and a data transmission unit (21) for transmitting the segment image data generated by the segment image generation unit to the server.

Description

[0001] Cross References to Related Applications [0002] This application claims the priority of Japanese Application No. 2018-016396 filed on February 1, 2018, the entire contents of which are incorporated herein. technical field [0003] The present disclosure relates to a vehicle image data generation device, a travel trajectory data generation system, a section image data generation program, and a storage medium. Background technique [0004] In the server, there is provided a configuration for generating trajectory data for automatic driving by performing image recognition on basic map data, aerial photograph data, and map data for navigation. However, in a configuration that performs image recognition on these various data, for example, in sections under elevated roads, in tunnels, and in sections where vehicles are parked, it may be difficult to recognize lane lines, and it may be difficult to generate travel track data. From such a situation, it is conceivable that ...
