Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a technique for suitably identifying a terminal position in an electric wire with a terminal.SOLUTION: An inspection device identifies a terminal position in an electric wire 8 with a terminal, the electric wire having a terminal part to which a terminal is connected. The inspection device comprises an imaging unit for imaging a connection part of the terminal and the electric wire 8 in the electric wire with a terminal, a template matching unit for comparing the image data obtained by the imaging unit with template data showing a feature portion which is a portion of the electric wire with a terminal, so as to identify a partial area PA1 matching the template data in the image data, and a terminal position identification unit for performing image analysis on an analysis range AR1 determined based on the position of the partial region AR1, so as to identify a position (position Y1) of a base end part 931 of a coated crimp part 93 which is a boundary portion between the terminal and the electric wire 8.SELECTED DRAWING: Figure 8
【課題】端子付電線における端子位置の特定を好適に行う技術を提供する。【解決手段】検査装置は、電線8の端末部に端子が接続された端子付電線における端子位置を特定する。検査装置は、端子付電線における端子及び電線8の接続部分を撮像する撮像部と、撮像部によって取得された撮像データ、及び、端子付電線の一部分である特徴部位を示すテンプレートデータを比較することによって、撮像データにおけるテンプレートデータにマッチする部分領域PA1を特定するテンプレートマッチング部と、部分領域AR1の位置に基づいて決定される解析範囲AR1を画像解析して、端子と電線8の境界部位である、被覆圧着部93の基端部931の位置(位置Y1)を特定する端子位置特定部とを備える。【選択図】図8 |
