The invention discloses an excavator work device measuring method based on a monocular camera. The method comprises the following steps of step1, designing an identification plate of pose measurement;step2, selecting an identification plate pasting position: pasting the identification plate on four articulation points of an excavator work device; step3, acquiring articulation point pixel coordinates and extracting a central point coordinate of the identification plate; and step4, carrying out coordinate conversion of the pixel coordinates and a world coordinate and acquiring the world coordinate of each articulation point so as to complete the pose measurement of the excavator work device. 本发明公开了种基于单目相机的挖掘机工作装置测量方法，包括：步骤1，设计位姿测量的标识板；步骤2，标识板粘贴位置的选取：将所述标识板粘贴于挖掘机工作装置的四个关节点；步骤3，获取关节点像素坐标，提取出所述标识板的中心点坐标；步骤4，进行像素坐标和世界坐标的坐标转换，得到各关节点的世界坐标，从而完成挖掘机工作装置的位姿测量。
