PROBLEM TO BE SOLVED: To display an accurate bird's-eye-view image without being influenced by a work member for construction.SOLUTION: A first front camera 4602A and a second front camera 4602B form a specific camera in which a portion to be a shadow of a work member 10B for construction becomes an imaging disabled dead-angle area by positioning the work member 10B for construction within an imaging range, and are installed so as to image the imaging range enough for obtaining a specific captured image with no dead-angle area in the case where captured images obtained from the cameras 4602A and 4602B are combined. Image combination means 52 generates the specific captured image by combining the captured images obtained from the first front camera 4602A and the second front camera 4602B. Bird's-eye-view image generation means 54 uses the specific captured image generated by the image combination means 52, thereby generating a first bird's-eye-view image in which an image of the work member 10B for construction is erased. 【課題】建設用作業部材の影響を受けることなく正確な俯瞰画像を表示する。【解決手段】第１前方カメラ４６０２Ａ、第２前方カメラ４６０２Ｂは、撮影範囲に建設用作業部材１０Ｂが位置することにより建設用作業部材１０Ｂの陰となった部分が撮像不能な死角領域となる特定カメラを構成し、それらカメラ４６０２Ａ、４６０２Ｂから得られる撮像画像を合成した場合に、前記の死角領域が無い特定撮像画像を得るに足る撮影範囲を撮像するように設置されている。画像合成手段５２は、第１前方カメラ４６０２Ａ、第２前方カメラ４６０２Ｂから得られた撮像画像を合成することで前記の特定撮像画像を生成する。俯瞰画像生成手段５４は、画像合成手段５２により生成された特定撮像画像を用いることにより建設用作業部材１０Ｂの画像が消去された第１の俯瞰画像を生成する。【選択図】図７
