A novel system to display position of explosion, shot angle, and trajectory of the rocket firing by using markerless augmented reality: ARoket: Improving safety and quality of exercise anytime, anywhere, and real time

摘要

The firing exercise of air-to-ground rocket should be run safely. The result and evaluation were to be reported quickly. Generally, the Weapon Impact Scoring Systems (WISS) displayed the rocket impact point by using PC monitor at a fixed location. This may produce the gap of real time information which expected by all safety components of exercise. In this paper, we proposed a novel system to visualize results of the rocket firing exercise anytime, anywhere, and realtime. The system called ARoket was developed based on the markerless Augmented Reality and run on Android-based smartphone. ARoket was integrated with current method of the rocket detection, Image Subtraction and 3D-View geometry. It displayed process of how the rocket hit the target which informed some important data such as the position of the rocket explosion and its angle when hitting the target area, which were extracted from the cloud database and visualized in 3D. This proposed system succeded to display the rocket trajectory on the firing range based on the output of WISS which were sent to the internet cloud database. The interchangeable maps installed in the Military Strategic Desk represented the firing range and its environment. By using smartphones in any different places, all officers who related to the firing exercise kept watching the screen of devices to observe the process of the rocket hitting the firing range, and evaluated the results quickly. This proposed system could be contributed to improve the quality and safety level of the exercise thoroughly, even in military or other aspects.
