To provide a distance estimation device capable of appropriately estimating a distance to another vehicle without excessively increasing an annotation cost of teacher data used for learning a discriminator.SOLUTION: A distance estimation device includes: a detection unit that detects another vehicle area representing another vehicle by inputting a peripheral image that represents a peripheral situation of a vehicle obtained from an imaging unit mounted on the vehicle to a discriminator, and classifies another vehicle represented in the detected other vehicle area into one of a plurality of pre-registered vehicle types; and an estimation unit that identifies a position of a virtual object corresponding to another vehicle represented in the other vehicle area and estimates a distance from the vehicle to the virtual object as a distance from the vehicle to the other vehicle.SELECTED DRAWING: Figure 8

    【課題】識別器の学習に用いる教師データのアノテーションコストを過大に増加させることなく他車両までの適切な距離推定を行うことができる距離推定装置を提供する。【解決手段】距離推定装置は、車両に搭載された撮像部から取得した車両の周辺状況を表す周辺画像を識別器に入力することで、他車両を表す他車両領域を検出するとともに、検出された他車両領域に表される他車両を予め登録された複数の車種のいずれかに分類する検出部と、他車両領域に表される他車両に対応する仮想物体の位置を特定し、車両から仮想物体までの距離を車両から他車両までの距離として推定する推定部と、を備える。【選択図】図8
