To efficiently perform position calculation processing of a vehicle based on detected markers by facilitating detection of the markers from a captured image captured by an imaging apparatus mounted on the vehicle.SOLUTION: A vehicle position calculation device includes: a captured image acquisition section for acquiring a captured image captured by an imaging apparatus mounted on a vehicle; an object equipment detection section for detecting object equipment from a captured image acquired by the captured image acquisition section; a marker detection section for detecting markers provided in the object equipment from the captured image acquired by the captured image acquisition section with the object equipment detected by the object equipment detection section as a search range; and a position calculation section for performing position calculation processing of the vehicle based on the markers detected by the marker detection section.SELECTED DRAWING: Figure 2

    【課題】車両に搭載された撮像装置が撮像した撮像画像からマーカーを検出することを容易にすることにより、検出されたマーカーに基づく当該車両の位置算出処理を効率よく実行する。【解決手段】車両に搭載された撮像装置が撮像した撮像画像を取得する撮像画像取得部と、撮像画像取得部が取得した撮像画像から対象設備を検出する対象設備検出部と、撮像画像取得部が取得した撮像画像から、対象設備検出部が検出した対象設備を探索範囲にして当該対象設備に設けられたマーカーを検出するマーカー検出部と、マーカー検出部が検出したマーカーに基づいて車両の位置算出処理を実行する位置算出部と、を備える。【選択図】図2
