Description
図1は、本開示に係るセンサ情報処理装置の一実施形態を示すハードウェア構成図である。本実施形態のセンサ情報処理装置100は、たとえば車両Vに搭載され、先進運転支援システム(Advanced Driver Assistance System:ADAS)や自動走行システム(Automated Driving:AD)の一部を構成する。
列である場合、点列情報を取得する機能F1において、中央処理装置101は、その認識結果をそのまま取得する。取得した点列の座標が、ローカル座標系の座標でない場合、中央処理装置101は、点列の座標をローカル座標系の座標に変換する。また、点列情報を取得する機能F1において、中央処理装置101は、各々の外界センサ200の認識処理時刻を、センサ情報処理装置100による処理周期の開始時刻に合わせる。
次に、図1、図3Aから図3C、図5から図9を援用し、図10を参照して、本開示に係るセンサ情報処理装置の実施形態2を説明する。図10は、本実施形態のセンサ情報処理装置100Aの機能ブロック図である。なお、図10は、実施形態1のセンサ情報処理装置100における図2および図4に対応している。
