To accurately estimate a movement amount even when luminance of a captured image has changed.SOLUTION: The movement amount estimation device includes an estimation unit, a detection unit, and a correction unit. The estimation unit estimates a movement amount of a vehicle on the basis of an optical flow that connects the same feature points in time-series captured images in which a periphery of the vehicle is captured. The detection unit detects a fluctuation period in which the movement amount estimated by the estimation unit repeats periodic fluctuations. The correction unit corrects a luminance value of the captured image when a fluctuation period is detected by the detection unit.SELECTED DRAWING: Figure 2

    【課題】撮像画像の輝度が変化した場合であっても、移動量を精度よく推定すること。【解決手段】実施形態に係る移動量推定装置は、推定部と、検出部と、補正部とを備える。推定部は、車両の周囲が撮像された時系列的な撮像画像における同一の特徴点を結んだオプティカルフローに基づいて車両の移動量を推定する。検出部は、推定部によって推定される移動量が周期的な変動を繰り返す変動期間を検出する。補正部は、検出部によって変動期間が検出された場合に、撮像画像の輝度値を補正する。【選択図】図2
