Abstract:
(EN) A server device 2 receives, from onboard devices 1 of a plurality of vehicles, matching decrease information D1 relating to voxels for which the degree of matching between point group data measured by a lidar 30 and point group data indicated by voxel data included in a map DB10 is low. The server device 2 then determines an object voxel Btag as a voxel to be updated on the basis of the matching decrease information D1, and updates the voxel data of the object voxel Btag on the basis of measurement data for which an overall evaluation function E is high.
(FR) L'invention concerne un dispositif de serveur 2 qui reçoit, en provenance de dispositifs embarqués 1 d'une pluralité de véhicules, des informations de réduction d'appariement D1 relatives à des voxels pour lesquels le degré d'appariement entre des données de groupe de points mesurées par un lidar 30 et des données de groupe de points indiquées par des données de voxel incluses dans une carte DB 10 est faible. Le dispositif de serveur 2 détermine ensuite un voxel d'objet Btag en tant que voxel à actualiser sur la base des informations de réduction d'appariement D1, et actualise les données de voxel de d'objet Btag sur la base de données de mesure pour lesquelles une fonction d'évaluation globale E est élevée.
(JA) サーバ装置2は、複数の車両の車載機1から、ライダ30が計測した点群データと地図DB10に含まれるボクセルデータが示す点群データとのマッチングの度合いが低いボクセルに関するマッチング低下情報D1を受信する。そして、サーバ装置2は、マッチング低下情報D1に基づき更新対象となる対象ボクセルBtagを決定し、総合評価関数Eが高い計測データに基づき、対象ボクセルBtagのボクセルデータを更新する。
