Abstract
Description
本願は、2016年8月3日に出願された米国仮特許出願第62/370,379号の優先権を主張し、その主題はその全体が参照により本明細書に組み込まれる。
a. 画像の左側(x=0)から、最初のxの値を求める。式中、PA(x)≦THRESHOLD_P0かつPA(x+1)≧THRESHOLD_P0である。この位置をpos_0(1)として記憶する。
b. 画像の右側(x=640、640×480センサの場合)から、最初のxを見出す。式中、PA(x)≦THRESHOLD_P0及びPA(x−1)≧THRESHOLD_P0である。この位置をpos_0(2)として記憶する。
a) パフォーマンス−例えば、操作者ごとのILのヒストグラム、コネクタの位置と種類をレポートできる。どの設置者にさらなる訓練が必要かを識別できる。プロジェクトの設置フェーズが終了する前に、リスクベースの限界パス接続を折よく識別できる。
b) 生産性−設置プロセスが監視されているため、集約的なデータを使用して生産性、各操作者、またはクルーごとの技能を推定できる。この情報は、より正確な時間の推定とより優れたリソースの割り当てで将来のプロジェクトを計画するのに役立つ。また、コネクタの使用状況を監視し、コネクタの在庫を事前に調達することもできる。
c) トラブルシューティング−各コネクタのプロファイルは異なる段階で記憶されるので、接続の不具合がコネクタ自体、設置方法、または機器の問題によるものであるかどうかを判断するための適切な情報がある。
