Description
本出願は、2015年4月6日に出願された米国特許出願第14/679,683号に対する優先権を主張し、それは、参照により全体として本明細書に組み込まれる。
[0027] 車両は、その車両の周囲の環境の様々な態様を検知するように構成された複数のセンサーを含み得る。例えば、車両は、異なる視野、距離、および/または目的を備えた、複数のLIDAR装置を含み得る。一例では、LIDAR装置は、狭いレーザービーム拡がりの単一ビームを含み得る。レーザービーム拡がりは、約0.1°×0.03°分解能であり得るが、他のビーム分解能も可能である。LIDARシステムは、車両のルーフに取り付けられ得るが、他の取付け位置も可能である。
[0035] 図1Aは、実施形態例に従った、車両100を示す。具体的には、図1Aは、車両100の右側面図、前面図、背面図、および上面図を示す。車両100は、図1Aでは自動車として例示されているが、前述のように、他の実施形態も可能である。更に、車両例100は自律モードで走行するように構成され得る車両として示されているが、本明細書で説明する実施形態は自律的に走行するように構成されていない車両にも適用可能である。従って、車両例100は制限することを意図していない。図のように、車両100は、5つのセンサー装置102、104、106、108、および110、ならびに、車輪112で例示される、4つの車輪を含む。
[0138] 図11は、実施形態例に従った、方法1100を示す。方法1100は、任意の順番で実行され得るブロックを含む。更に、様々なブロックが、本開示の意図する範囲内で、方法1100に追加され得るか、または方法1100から取り去られ得る。方法1100は、図1A~図1E、図2、図3A~図3B、図4A~図4B、図9、または図10を参照して例示および説明したシステムのいずれかまたは全部を使用して実行され得るステップに対応し得る。
