To provide a transfer object work-piece height measuring system capable of correctly measuring a height of a transfer object work-piece.SOLUTION: A transfer object work-piece height measuring system comprises: an imaging unit 3 for obtaining information on three-dimensional point groups of a plurality of loaded work-pieces and obtaining information on three-dimensional point groups of a plurality of loaded work-pieces after temporarily moving a transfer object work-piece; and a box height estimation unit 406 for selecting information on three-dimensional point groups to be an object of flat surface fitting, which is used for acquiring a flat surface of the work-piece necessary for measuring the height of the work-piece, from the information on three-dimensional point groups acquired at the imaging unit 3.SELECTED DRAWING: Figure 2 【課題】移載対象ワークの高さを正確に計測することができる移載対象ワーク高さ計測システムを提供する。【解決手段】荷積みされた複数のワークの三次元点群情報を取得し、移載対象ワークを仮移動させた後の荷積みされた複数のワークの三次元点群情報を撮像部３と、ワークの高さを計測する際に必要な当該ワークの平面を取得する際に用いられる平面フィッティングの対象となる三次元点群情報を撮像部３にて取得された三次元点群情報から選別する箱の高さ推定部４０６と、を有してなる。【選択図】図２
