Description

上述した課題を解決するために本発明の車両周辺画像表示装置および車両周辺画像表示方法は、車載カメラによって得られた撮影画像を視線変換することによって撮影俯瞰画像を生成し、得られた撮影俯瞰画像を記憶する。また、撮影俯瞰画像に移動体が存在する場合には撮影俯瞰画像中での移動体の位置も記憶しておく。そして、車両の移動量に関する移動情報を取得して、記憶しておいた撮影俯瞰画像の中から、車両の死角領域を撮影した部分の画像である履歴画像を切り出して、撮影俯瞰画像と共に表示画面上に表示する。この時、履歴画像中に移動体が存在する場合には、その移動体が撮影俯瞰画像中に存在していた場合とは異なる態様で履歴画像を表示する。 In order to solve the above-described problems, the vehicle periphery image display device and the vehicle periphery image display method according to the present invention generate a photographic overhead view image by performing line-of-sight conversion on a captured image obtained by an in-vehicle camera, and the obtained photographic overhead view. Store the image. Further, when a moving body is present in the photographic overhead image, the position of the moving body in the photographic overhead image is also stored. Then, movement information relating to the amount of movement of the vehicle is acquired, and a history image, which is an image of a portion where the blind spot area of the vehicle is photographed, is cut out from the stored photographing bird's-eye view image and displayed together with the photographing bird's-eye view image Display above. At this time, if a moving object exists in the history image , the history image is displayed in a different manner from the case where the moving object exists in the captured overhead image.

こうすれば、表示画面上で履歴画像の表示態様が変わるので、移動体が履歴画像によって表示されていることを運転者に認識させることができる。その結果、運転者は、例えば直接目視するなどして移動体を確認しようとするので、移動体の位置を誤解する虞を回避することが可能となる。 This changes the display mode of the history image on the display screen, so that the driver can recognize that the moving body is displayed by the history image. As a result, the driver tries to confirm the moving body by, for example, direct visual observation, so that it is possible to avoid the possibility of misinterpreting the position of the moving body.

Claims
