To provide a device and method for detecting a dead angle in a warehouse that can detect dead angle areas caused by the placement of luggage in the passenger compartment when pallets are used as luggage storage areas.SOLUTION: A device for detecting dead angles in a warehouse is provided with a mechanical parking device 100 having a laser radar device 12 and a data processing device 14, and a plurality of carriages 20. The laser radar device 12 scans the whole area of a pallet positioned at a boarding/unloading position with a laser beam 6 and detects three-dimensional coordinates of its reflection position RP. The carriage 20 has a preset carriage width CB and a carriage length CL, and can be laid flat on a pallet. The data processing device 14 estimates the arrangement pattern AP of the carriage 20 from the three-dimensional coordinates, detects an undetected area BA on the pallet from the arrangement pattern AP, and detects a dead angle area BC from the undetected area.SELECTED DRAWING: Figure 4 【課題】パレットを荷物の収納場所として利用する際に、乗降室内の荷物の配置により生じる死角領域を検出することができる庫内死角検出装置と方法を提供する。【解決手段】レーザーレーダー装置１２とデータ処理装置１４を有する機械式駐車装置１００と、複数の台車２０と、を備える。レーザーレーダー装置１２は、乗降位置に位置するパレット全域にレーザ光６を走査してその反射位置ＲＰの３次元座標を検出する。台車２０は、予め設定された台車幅ＣＢと台車長ＣＬとを有し、パレット上に平置き可能に構成されている。データ処理装置１４は、３次元座標から台車２０の配置パターンＡＰを推定し、配置パターンＡＰからパレット上の未検出領域ＢＡを検出し、未検出領域から死角領域ＢＣを検出する。【選択図】図４
