Abstract
To obtain a self-position error estimation device and a self-position error estimation method with which it is possible to calculate errors of the self-position of a moving vehicle with high accuracy.SOLUTION: The self-position error estimation device comprises: an image acquisition unit that acquires an image of the surrounding of a moving vehicle that is captured by an imaging unit mounted to the moving vehicle; a first error calculation unit that, when calculating the current self-position of the moving vehicle on the basis of images and map data, calculates a first error of the self-position on the basis of errors of the map data; a second error calculation unit that calculates a second error of the self-position when it is considered that no errors exist in the map data; and a third error calculation unit that calculates a third error of the self-position including the first and second errors.SELECTED DRAWING: Figure 4
