The extraction mechanism of ship list and ship trajectory based on the requested region for VTS

摘要

These days, we can easily listen maritime accidents in the news. It is because material, human movement is growing in the ocean has been extended to a variety of marine leisure activities. It was used for the conventional recording and playback functions of the VTS system most frequently for the analysis of maritime accident when the accident occurs. The accident occurrence time, and suspicious ship confirmed using the playback function of the existing VTS system has a big problem that it takes a lot of time. Particularly, if you do not know the exact occurrence time, such as fishing nets, damaging accidents causing damage to the ship was required a lot of time and effort to analyze the accident time. This paper proposes the mechanism that is used in post-processing maritime accident. The proposed mechanism is to quickly and efficiently identify the accident when used alone or with a conventional playback function in VTS system in a manner that the pre-extraction ship trajectory information on the accident area and the specific time condition.
