Summary:To facilitate executing a simulation test for an autonomous travel vehicle by exactly developing obstacle information capable of reflecting an objective scene with a three-dimensional scene map on the basis of obstacle information in a subsequent three-dimensional scene map.SOLUTION: A simulation test for obstacle includes: connecting with actual identification performance of an identification algorithm test object for obstacle information in a three-dimensional scene map, determining Gauss distribution information of an obstacle position detected by an identification algorithm and adjusting respective position points in an initial locus sequence of a simulation obstacle to make a location deviation between respective points in a target movement locus sequence after the adjustment and a corresponding position point in the initial movement locus sequence follow a Gauss distribution; and adding the target movement locus sequence of the simulation obstacle to the three-dimensional scene map.SELECTED DRAWING: Figure 1 【課題】3次元シーンマップで客観的なシーンを反映することができる障害物情報を正確に構築して、後続の3次元シーンマップ内の障害物情報を基に、自律走行車に対してシミュレーションテストを行うことを容易にする。【解決手段】3次元シーンマップ内の障害物情報に対して、認知アルゴリズムテスト対象の実際の認知性能と結合して、認知アルゴリズムによって検出された障害物位置のガウス分布情報を決定し、模擬障害物の初期軌跡シーケンス内の各位置点を調整することにより、調整後の目標移動軌跡シーケンス内の各位置点と、初期移動軌跡シーケンス内の対応する位置点との間の位置偏差はガウス分布に従うようになり、模擬障害物の目標移動軌跡シーケンスを3次元シーンマップに追加する。【選択図】図1
