作業指引可以幫助資淺工作者遵循正確的作業程序,確保人機共存組裝線之作
業協調性。本研究針對 GPU 組裝線提出一種透過深度學習的智慧作業指引模型,
使用卷積神經網絡 YOLOv3 的物件檢測機制和決策樹分類器 CART 的動作識別機
制,作為模型核心。在此人機協作組裝線上,透過三個獨立的攝影機監控所有
物件(如:風扇、主機板、GPU、機器人、工作者頭部、工作者身體、螺絲鎖附
機、螺絲起子等)。動作檢測是由三個攝影機輸入目標物件的坐標和速度,並
執行三個平行且獨立的決策樹分類器來完成,最終輸出作業建議。本研究透過
GPU 組裝過程完成模型的評估,F1-score 達到 0.96。此智慧模型有助於裝配過
程中,向資淺工作者提供即時有效的工作指導。
Operations advice system can help junior workers to follow standard operations
procedure, which is critical to a human-robot coexisted assembly line to guarantee
harmonious tasks. In this study, a smart operator advice model by deep-learning is
proposed for a GPU assembly line. Two mechanisms are built as the core of the model,
which is an object detection mechanism using convolutional neural network YOLOv3
and a motion recognition mechanism using decision tree classifier CART. The object
detection is conducted by 3 parallel and independent cameras monitoring all the objects
(e.g., fan, motherboard, GPU, robot, head, body, screwing machine, screwdriver) in the
assembly line. The motion detection is done by three parallel and independent decision
tree classifiers by the three cameras where the input is the coordinates and speed of
objects. The final output isthe task advice given by the proposed operator advice model.
The evaluation of the model is done through a case study of a GPU final assembly
process. F1-score shows a value of 0.96 by the model. The smart model facilitates
informative instruction to the junior operator during the assembly process in real time.
