Title: POSITION ESTIMATION DEVICE, SERVER DEVICE, POSITION ESTIMATION METHOD, MAP INFORMATION UPDATE METHOD, POSITION ESTIMATION PROGRAM, MAP INFORMATION UPDATE PROGRAM, RECORDING MEDIUM, AND MAP INFORMATION
Abstract:
The present invention enhances the accuracy in estimating the position of a moving body even if the moving body moves through a location having a changing state. In the present invention, map information using a plurality of voxels to express the state in the vicinity of a location that a moving body can move through is stored in a storage unit, vicinity information expressing the state of the vicinity of the moving body is acquired, the position of the moving body is estimated through the use of the map information and vicinity information, and the position of the moving body is estimated through the additional use of reliability information that is associated with and indicates the reliability of at least one voxel from among the plurality of voxels and affects the estimation of the position of the moving body.
