Abstract
This paper applies depth images and a 3D simulation to introduce a safety system for manufacturing facilities. Smart systems have recently become an important topic for use in the manufacturing industry, and these are now being developed with newly-introduced A.I.-based technologies. Smart manufacturing systems introduced with A.I. enable more efficient production than before, but these offer limited improvements at first. To further enhance production, collaborative intelligence can combine human creativity with the speed and accuracy of the equipment, complementing the shortcomings of each production method. However, collaboration in existing facilities requires new safety measures for workers because there is a higher propensity for accidents due to collisions. A recent study on worker-equipment collisions has shortcomings in that a collision between workers and equipment is inevitable because whether or not a collision occurs with a worker is checked only by using a sensor inside the robot. Therefore, this study installs a depth image camera outside the equipment, not a sensor inside, and the system can produce simulations in advance in a virtual environment before finalizing the design of the operation and equipment. A comparison of a simulation to the actual movement of a robot arm toward the point of collision with a worker confirmed an error of about 10.048 cm. Through this, it is possible to detect worker-equipment collision in advance. Keywords Depth Image Camera . Multimedia Tools . 3D Simulation . Cyber-Physical Systems . Autonomic Computing . MTConnect

Multimedia Tools and Applications
1 Introduction The fourth industrial revolution has been brought about by rapid technological advances that allow for smarter resource management during manufacturing. In addition, customers now demand customized products in a short amount of time with changing needs. In the face of these challenges, Cyber Physical Systems (CPSs) have been actively studied [3]. The goal of a CPS is to intelligently monitor and control the world in which we live using advanced cyber infrastructure. CPSs can be useful in aerospace, energy systems, medical, transportation, and manufacturing [30, 38]. Among these, the manufacturing industry is expected to use CPSs to improve the efficiency and safety of entire factories by turning them into smart factories with improvements in production efficiency, energy consumption, and safety for hazardous areas. In order to implement CPSs, it is necessary to integrate existing heterogeneous sensors and equipment, ensuring real-time and relia
