The invention relates to a ground object data collection device, a ground object data collection method, and a computer program for collecting ground object data. A ground object data collection device is provided with: a storage unit that stores map information including, for each position, a probability distribution indicating the degree of reliability of the presence of a ground object at the position; a reception processing unit that stores the received ground object data in the storage unit every time the ground object data indicating the position of the ground object is received from any one of the one or more vehicles via a communication unit capable of communicating with the vehicle; an update unit that updates a probability distribution indicating the reliability of the presence of the ground object at each position on the basis of the position of the ground object indicated by each of the received one or more pieces of ground object data; and a collection stop instruction unit that transmits, via the communication unit, an instruction to stop the collection of the ground object data to the one or more vehicles with respect to the ground object for which the degree of extension of the updated probability distribution is equal to or less than a predetermined threshold value.
本发明涉及地上物数据收集装置、地上物数据收集方法及地上物数据收集用计算机程序。地上物数据收集装置具有:存储部,存储包含针对每个位置表示在该位置处存在地上物的可靠度的概率分布的地图信息;接收处理部,每当从一台以上车辆中的任意车辆经由能够与该车辆进行通信的通信部接收到表示地上物位置的地上物数据时,将接收到的地上物数据存储于存储部;更新部,根据接收到的一个以上的地上物数据各自所表示的地上物的位置,更新表示每个位置的存在地上物的可靠度的概率分布;收集停止指示部,关于更新后的概率分布的扩展程度为预定的阈值以下的地上物,经由通信部对一台以上车辆发送停止收集地上物数据的指示。
