At chemical plant and such as factory, all plant maintenance work must be done accurately based on process document. Accordingly we propose a method that automatically recognizes progress of work from pictures of machines which are on maintenance or dismantling to indicate accurate tasks depends on progress to workers. We implement our system to tablet PC and we embedded in the client server system to manage data centrally. Finally we prove the effectiveness of our system by operational test that pictures which are taken at workspace are correctly sent to server to judge which process the work does and show tasks to client side PC automatically and correctly.
