Abstract
Description
実施の形態1.
図1はこの発明の実施の形態1におけるナビゲーション装置の構成を示すブロック図であり、入力部1、現在地検出部2、案内ルート計算部3、地図データベース4、地図作成部5、案内ルート周辺施設アイコン配置部6、表示部11から構成されている。
まず、右左折交差点案内ルート周辺の施設アイコンの抽出について説明する。
図3(a)が示すように、案内ルート周辺施設アイコン抽出部7は案内ルートから距離Tの範囲にある施設アイコンA,Bを一次抽出する。距離Tとは案内ルートに面している施設アイコンのみが含まれる距離とする。そして、図5(a)で示すような種別優先度、図5(b)で示すような種別内優先度に基づき、優先度がつけられている施設アイコンAのみを表示部11で表示するアイコンとして抽出する。この実施の形態においては、アイコンBは優先度「なし」のアイコンであり、案内ルート周辺施設アイコン抽出部7において最終的に抽出されない。
図4(a)が示すように、案内ルートから距離Tの範囲にある施設アイコンA,Bを抽出する。距離Tとは、案内ルートに面している施設アイコンA,Bのみが含まれる距離とする。施設アイコンA,Bを抽出する優先順位のつけ方は、図5(a)、図5(b)と同様である。優先順位がつけられていない施設アイコンBに関しては抽出を行わない。この結果、図4(b)が示すように、案内ルート周辺の1つの施設アイコンAが抽出される。
施設アイコンAのオフセットの方法として、施設アイコンAがある位置(施設アイコン原位置)を中心にして、その周囲でオフセット先を探し移動するという方法が考えられる。しかしながらこの方法は、右左折交差点案内ルート周辺の場合、交差点形状に適応して施設アイコンAをオフセットしたり、オフセットされた施設アイコンA’が施設アイコン原位置に対して直感的に理解できる位置に配置することが難しいという課題がある。
まず、右左折交差点案内ルート周辺にある施設アイコンAの配置ルールについて説明する。図6(a)で示すように、交差点を中心とした半径Dの円形エリア内にある施設アイコンAは、交差点を中心とした半径Eの円周上に施設アイコンA'として配置するものとする。半径Dは、距離Tと同じ長さである。
半径Eは、
であらわされる。
lは、オフセット配置する大きな施設アイコンA'の一辺の長さである。オフセット配置する大きな施設アイコンA'は、通常の施設アイコンAの数倍の大きさを想定している。
図7(a)で示すように、案内ルートから距離Tの線分上に施設アイコンを配置するものとする。
距離Tは、
であらわされる。
図7(b)で示すように、施設アイコン原位置を通る案内ルートの法線を引く。図7(c)で示すように、施設アイコン原位置を通る案内ルートの法線と距離Tの線分が交差するポイントに、大きなサイズの施設アイコンA'(一辺がlの正方形)の中心を配置する。道なり案内ルート周辺にある施設アイコンは、右左折交差点案内ルート周辺にある施設アイコンよりも小さなサイズにして差別化しても良い。
ステップST204において、表示部11はステップST203に基づきオフセット配置された施設アイコンA'を入力する。施設アイコン原位置と施設アイコン関連付け部13が、施設アイコンAの原位置と施設アイコンA'の関連付けを行いフローを終了する。
図8はこの発明の実施の形態2におけるナビゲーション装置の一例を示す構成図である。入力部1から配置ルール格納部10までの構成は、実施の形態1と同じであるので、同一部分には同一符号を付して重複説明を省略する。配置結果評価部14は、施設アイコンA'の再配置が必要か否かを配置結果評価知識格納部15から読み出した配置結果評価知識を利用して判定を行う。施設アイコン再配置部16は、再配置が必要な場合、施設アイコンA'の再配置を行う。表示部11は実施の形態1の表示部に施設アイコン変更部17を付加したものである。
ステップST303において、施設アイコン配置部9はステップST302に基づき抽出された案内ルート周辺の施設アイコンAを入力し、配置ルール格納部10から読み出した配置ルールを利用して施設アイコンA'をオフセット配置して出力する。
ステップST304において、配置結果評価部14はステップST303に基づきオフセット配置された施設アイコンA'を入力し、配置結果評価知識格納部15から読み出した配置結果評価知識を利用して、施設アイコンA'の再配置が必要か否かを判定する。
配置結果評価知識は、図16に示すように、オフセットした施設アイコンA'と案内ルートが重なっていないか、複数の施設アイコン同士が重なっていないかを判定する知識である。この配置結果評価知識において再配置が必要と判定された場合は、ステップST303に戻り、施設アイコン再配置部16を利用して施設アイコンA'の再配置を行う。再配置が必要ないと判定された場合は、ステップST305へ進む。
施設アイコン再配置部16には、オフセットした施設アイコンA'と案内ルートが重なっている場合と、複数の施設アイコン同士が重なっている場合に、重ならないように修正するために施設アイコンA'の再配置を行う。
図10(a)に示すように、右左折交差点周辺でオフセットした施設アイコンA'が案内ルートと重なってしまった場合、図10(b)に示すように施設アイコンA'を交差点を中心とした半径Eの円周上を移動させ案内ルートと重ならないように再配置を行う。この際、施設アイコンA'が案内ルートをまたがない範囲で移動を行う。
図12(a)に示すように、右左折交差点周辺案内ルートでオフセットした施設アイコンA'「1」、「2」同士が重なってしまった場合、図12(b)で示すように、優先順位の低い施設アイコンA'「2」を交差点を中心とした半径Eの円周上を移動させて施設アイコン同士が重ならないように再配置する。施設アイコンA'の優先順位は、種別優先度(図5(a))、種別内優先度(図5(b))で定められている。この際、優先度の一番高い施設アイコンA'「1」は、移動させないものとする。また、施設アイコンA'「2」が案内ルートをまたがない範囲で移動を行う。
複数の施設アイコンA'「1」、「2」の位置関係によっては、この2つの再配置処理を併用しても良い。また、優先順位の低い施設アイコンA'「2」を非表示にするという処理を行っても良い。
ステップST305において、施設アイコン原位置表示部12と施設アイコン原位置と施設アイコン関連付け部13はステップST303に基づきオフセット配置された施設アイコンA'を入力し、施設アイコン原位置と施設アイコンA'の関連付けを行いフローチャートを終了する。
上記実施の形態2においては、施設アイコン再配置部16を用いて施設アイコンA’の再配置を行う例を説明したが、案内ルート周辺施設アイコン配置部6において案内ルートや他の施設アイコンと重ならないオフセット位置を決定しても良い。すなわち、右左折交差点を中心に施設アイコンを放射状にオフセットするときにオフセット後の施設アイコンA’が案内ルートと重ならないようにするために、交差点からの距離Eを施設アイコンA’が案内ルートと重ならない距離に決定するよう、配置ルール格納部10に予め配置ルールを格納しておく。例えば、右左折交差点の角度が小さいほど距離Eを長くする等のルールを格納しておけばよい。また、オフセット後の施設アイコンA’同士が重ならないようにするために、オフセットする施設アイコンの数やオフセット後の施設アイコンA’の大きさに応じて、オフセットする交差点からの距離Eを決定するよう、予め配置ルール格納部10に配置ルールを格納しておく。複数の施設アイコンのうちの一部について、オフセットする交差点からの距離Eを変化させるようにしても良い。
