The invention discloses a position accuracy determination apparatus, a storage medium and a determination method. Provided is a position accuracy determination device capable of determining a state of accuracy of an estimated current position of a moving object. The position accuracy determination device estimates a first position of the moving object at a first time point on the basis of an image indicating a road feature on a road surface around the moving object at the first time point and position information of the road feature on the road surface. A second position of the moving object at the first time is estimated from a position of the moving object at a second time before the first time and a movement amount and an azimuth angle change amount of the moving object from the second time to the first time, and the first position and the second position at the first time are input to a prediction filter to calculate a current position of the moving object at the first time. The state of accuracy of the current position of the moving object is determined on the basis of a first difference between the current position of the moving object at the first time point and a position estimated on the basis of the position of the moving object at a time point before the first time point and the amount of movement and the azimuth angle change amount of the moving object from the time point before to the first time point.
公开位置精度判定装置、存储介质以及判定方法。提供能够判定推测的移动物体的当前位置的精度的状态的位置精度判定装置。位置精度判定装置根据第1时刻下的表示移动物体的周围的路面上的道路特征物的图像和路面上的道路特征物的位置信息,推测第1时刻下的移动物体的第1位置,根据第1时刻以前的第2时刻下的移动物体的位置和从第2时刻至第1时刻的移动物体的移动量以及方位角变化量,推测第1时刻下的移动物体的第2位置,将第1时刻下的第1位置以及第2位置输入到预测滤波器,计算第1时刻下的移动物体的当前位置,根据第1时刻下的移动物体的当前位置与基于第1时刻以前的时刻下的移动物体的位置和从以前的时刻至第1时刻的移动物体的移动量以及方位角变化量推测的位置之间的第1相异量,判定移动物体的当前位置的精度的状态。
