1. A workflow monitoring and analysis method, comprising the steps of: detecting, by a first image capturing module, at least one feature of at least one detection zone of a detection material, wherein the first image capturing module is a charge-coupled device (CCD); generating, by the first image capturing module, an image information according to the at least one feature being detected; generating, by a task model database, at least one three-dimensional joint coordinate according to the image information; generating, by the task model database, at least one task posture information according to the at least one three dimensional joint coordinate; generating, by a workpiece posture module, a workpiece posture information according to the image information; capturing, by a second image capturing module, movements of the detection material, wherein the second image capturing module is a depth camera; generating, by the second image capturing module, a movement information according to the movements of the detection material; generating, by a detection zone movement module, at least one three-dimensional track information according to the movement information of the detection material; generating, by a workpiece movement module, at least one workpiece track information according to the movement information of the detection material; generating, by the task model database, a task track information according to the three-dimensional track information; generating, by the task model database, a task semantics according to the task posture information and the task track information; and outputting, by an output module, the task semantics for use in a hybrid automation device.
