The information processing apparatus includes an input interface, a processor, and an output interface. The input interface acquires observation data derived from an observation space. The processor detects a detection object included in the observation data. The processor converts the detected coordinate map of the detection object into coordinates of the detection object in a virtual space, tracks the position and velocity of a mass point representing the detection object in the virtual space, and converts the coordinate map of the tracked mass point in the virtual space into coordinates in a display space. The processor sequentially observes the size of the detection object on the display space, and estimates the size of the detection object on the basis of an observed value of the size of the subject image at the current point in time and an estimated value of the size of the past subject image. The output interface outputs output information on the basis of the coordinates of the mass point transformed onto the display space by the mapping and the estimated size of the detection object.

    信息处理装置具备:输入接口、处理器以及输出接口。输入接口获取从观测空间得到的观测数据。处理器检测观测数据中包含的检测对象。处理器将检测出的检测对象的坐标映射变换为虚拟空间的检测对象的坐标,在虚拟空间上追踪表示检测对象的质点的位置以及速度,将追踪到的质点的虚拟空间上的坐标映射变换为显示空间上的坐标。处理器依次观测显示空间上的检测对象的大小,基于当前时间点的被摄体图像的大小的观测值和过去的被摄体图像的大小的推定值,推定检测对象的大小。输出接口输出基于映射变换到显示空间上的质点的坐标以及推定出的检测对象的大小的输出信息。
