WebRTC를 이용한 지적측량 현장 영상 송출 방안 연구

WebRTC technology enables high-definition, low-latency video services anytime, anywhere through a wired or wireless network, regardless of the location of the camera. When using this service to transmit cadastral survey field video, land owners and interested parties can remotely attend the work field. In addition, the field environment related to land boundary establishment at the time of cadastral survey can be stored and managed, so it can be used as basis data in the event of a land boundary-related dispute in the future. In this study, open land (farming and residential) and forest areas were selected as experimental areas considering the topographical characteristics of the cadastral survey performance environment. We also attempted to transmit cadastral survey field video using WebRTC technology and evaluate its quality. Through this, we attempted to suggest the possibility of application to cadastral surveying fields. As a result of analyzing the bit rate, packet loss, and jitter of the video transmission service through experiments in the study area, the overall quality level and system stability in open areas were found to be very good. In the case of forest areas, the video quality level was low and system stability was found to be low due to the characteristics of the communication environment. However, if mobile communication becomes smoother in forest areas, it is believed that it is possible to implement a real-time cadastral survey video transmission service even in forest areas. If the results of this study are used, efficiency can be enhanced by allowing land owners to attend the work field face-to-face or non-face-to-face when performing cadastral surveying. In addition, it is expected that it will be possible to minimize the costs required to investigate various basis materials in the event of a land boundary-related dispute in the future.
