description This radiowave propagation estimation device uses identification information that can identify objects that include structures, and map data that includes structures, and, on the basis of the identification information, extracts object structures that are visible from both the direct or simulated transmission point of radiowaves and the direct or simulated reception point of radiowaves. The radiowave propagation estimation device uses information indicating the characteristics of the extracted object structure to estimate the radiowave propagation characteristics. Un dispositif d'estimation de propagation d'ondes radio utilise des informations d'identification qui peuvent identifier des objets qui comprennent des structures, ainsi que des données cartographiques qui comprennent des structures, et, sur la base des informations d'identification, extrait des structures d'objet qui sont visibles à la fois depuis le point d'émission direct ou simulé d'ondes radio et le point de réception direct ou simulé d'ondes radio. Le dispositif d'estimation de propagation d'ondes radio utilise des informations indiquant les caractéristiques de la structure d'objet extraite pour estimer les caractéristiques de propagation d'ondes radio. 電波伝搬推定装置は、構造物を含む物体を識別可能な識別情報と、構造物を含む地図データとを用い、当該識別情報に基づいて、電波の直接的または擬似的な送信点、及び電波の直接的または擬似的な受信点の両方から見える物体の構造を抽出する。電波伝搬推定装置は、抽出した物体の構造の特徴を示す情報を用いて、電波の伝搬特性を推定する。
