本揭露提供用於分類手工具的工具臂的組裝長度的系統及其方法。方法包括根據3D點雲及二維影像，取得分別對應於工具臂的末端部及樞接部的末端邊緣3D特徵、樞接部本體3D特徵及樞接部邊緣3D特徵；根據3D點雲、二維影像、樞接部本體3D特徵及樞接部邊緣3D特徵計算長度測量向量；根據長度測量向量，取得對應末端邊緣3D特徵的末端切平面及對應樞接部邊緣3D特徵的樞接切平面；以及計算末端切平面及樞接切平面的距離，以取得工具臂的組裝長度。

A system and method for measuring assembling length of clamping arm of hand tool are provided by the disclosure. The method includes: obtaining a tip region and a base region for respectively obtaining a tip edge 3D feature, a pivot body 3D feature and a pivot edge 3D feature respectively corresponding to a tip portion and a pivot portion of the hand tool, according to a 3D point cloud and a 2D image; calculating a length measuring vector according to the 3D point cloud, the 2D image, the pivot body 3D feature and the pivot edge 3D feature; obtaining a tip tangent plane corresponding to the tip edge 3D feature, and a pivot tangent plane corresponding to the pivot edge 3D feature; and calculating the distance between the tip tangent plane and the pivot tangent plane, to obtain the assembling length of the clamping arm.
