To provide a road-vehicle cooperation system capable of keeping communication capacity low while maintaining high accuracy of drive support information and low cost of a vehicle.SOLUTION: A road-vehicle cooperation system includes: a sensor including an imaging device mounted on a vehicle; a road-vehicle cooperation server for receiving sensor data including an image from the sensor and creating a dynamic map based on an image of an object detected from the image; a position prediction device for predicting positions of both object and vehicle at the time of next imaging by the imaging device; an area estimation device for estimating a target area that is an area including the image of the object in the image picked up at the time of next imaging by the imaging device based on installation conditions of the imaging device and the positions of both object and vehicle at the time of the next imaging by the imaging device predicted by the position prediction device; and a data amount reducing device for reducing an amount of transmission data of the image by transmitting the image at a first resolution in the target area and at second resolution lower than the first resolution in the area other than the target area of the image when the image is transmitted from the imaging device to the road-vehicle cooperation server.SELECTED DRAWING: Figure 2
【課題】運転支援情報の精度を高く、かつ車両のコストを低く維持しながら、通信容量を低く抑えることができる路車協調システムを提供する。【解決手段】路車協調システムは、車両に搭載された撮像装置等を含むセンサと、これらから画像を含むセンサデータを受信し、画像等から検知された物体の像に基づいてダイナミックマップを作成する路車協調サーバと、撮像装置による次回の撮像時における、物体及び車両の双方の位置を予測する位置予測装置と、撮像装置の設置条件、並びに位置予測装置により予測された、撮像装置による次回の撮像時における物体及び車両の双方の位置に基づいて、撮像装置による次回の撮像時に撮像された画像内における、物体の像を含む領域である対象領域を推定する領域推定装置と、撮像装置から路車協調サーバへの画像の送信時に、対象領域は第1の解像度で、画像の対象領域以外の領域は第1の解像度より低い第2の解像度で、それぞれ送信することにより画像の送信データ量を削減するデータ量削減装置とを含む。【選択図】図2
