  "textContent": "To provide a vehicle position estimation system that estimates a position of a vehicle using a landmark and that is capable of suppressing the problem of deterioration of position estimation accuracy which may be caused by surrounding environment in which the vehicle travels. [0002] An onboard control device that is installed at a vehicle acquires land mark information including position information of a landmark which can be recognized on a road in which the vehicle is estimated to travel by a camera, a landmark image for recognition, a recognition evaluation value that represents ease of the recognition successfully performed and so on, and selects a landmark to be a subject for recognition based on the recognition evaluation value included in the landmark information. The onboard control device further evaluates the recognition results of the landmark to be a subject for recognition, and transmits the recognition results to the server with the landmark image recognized by the camera. The server aggregates the recognition evaluation results of the landmark and the recognized images received from the camera and reflects them in the recognition evaluation values for the landmark information and landmark images for recognition to be transmitted to the onboard control device.",
