To provide a picking truck which allows a user to confirm the lower side of a control platform without the user leaning out of the control platform.SOLUTION: A picking truck C comprises: a lower camera 3; an image extraction unit; a projector 5; a projection image camera 6; a correction coefficient output unit; and a correction processing unit. The lower camera 3 images the lower side of a control platform 2 to generate a first lower image. The image extraction unit extracts a second lower image to be projected from the first lower image. The projection image camera 6 images the second lower image projected onto a pallet P or the like by the projector 5 to generate a projection image. The correction coefficient output unit outputs a correction coefficient of each luminance of each color component of each pixel of the second lower image on the basis of each luminance of each color component of each pixel of the second lower image and each luminance of each color component of each pixel of the projection image. The correction processing unit corrects each luminance of each color component of each pixel of the second lower image on the basis of the correction coefficient. The projector 5 projects the corrected second lower image onto the pallet P or the like.SELECTED DRAWING: Figure 1

    【課題】ユーザが運転台から身を乗り出さなくても運転台の下方を確認することができるピッキングトラックを提供する。【解決手段】ピッキングトラックCは、下方カメラ3と、画像抽出部と、プロジェクタ5と、投影画像カメラ6と、補正係数出力部と、補正処理部と、を備える。下方カメラ3が運転台2の下方を撮像し第1下方画像を生成し、画像抽出部が投影すべき第2下方画像を第1下方画像から抽出する。投影画像カメラ6が、プロジェクタ5によってパレットPなどに投影された第2下方画像を撮像して投影画像を生成し、補正係数出力部が第2下方画像の各画素の各色成分の各輝度と、投影画像の各画素の各色成分の各輝度とに基づいて、第2下方画像の各画素の各色成分の各輝度の補正係数を出力する。補正処理部が補正係数に基づいて第2下方画像の各画素の各色成分の各輝度を補正し、プロジェクタ5が補正された第2下方画像をパレットPなどに投影する。【選択図】図1
