Zusammenfassung:	To provide a map creation method and map creation device that can compress the amount of information and obtain a region with a required high resolution.SOLUTION: A radar 3 that detects a peripheral object and terrain and a LIDAR 4 that can detect the peripheral object and terrain in a narrow detection range and with higher resolution compared with the radar 3 are provided. A map creation method includes: a second map creation step of creating a second map with a high resolution based on peripheral information detected by the LIDAR 4; a first map creation step of creating a first map with a wide area based on peripheral information detected by the radar 3; and a synthetic map creation step of creating a synthetic map having a first map grid width and a second map grid width.SELECTED DRAWING: Figure 2 【課題】情報量の圧縮が可能で且つ必要に応じた解像度の高い領域を得ることができる地図生成方法および地図生成装置を提供する。【解決手段】周囲の物体および地形を検出するレーダ３と、レーダ３に比べて検出範囲が狭く且つ高解像度で周囲の物体および地形を検出可能なＬＩＤＡＲ４とを備える。ＬＩＤＡＲ４によって検出された周囲の情報に基づいて高解像度の第２の地図を生成する第２地図生成ステップと、レーダ３によって検出された周囲の情報に基づいて広域の第１の地図を生成する第１地図生成ステップと、第１の地図の格子幅と第２の地図の格子幅を有する合成地図を生成する合成地図生成ステップとを備える。【選択図】図２
