Cadastral Survey Data Acquisition Apparatus using Ortho Image of Drone and Method Thereof

摘要

The present invention is used as a navigation data for accurate prior information extraction of one parcel survey in the case of cadastral surveying and cadastral re-investigation projects, grasping and analyzing the current status of the lot to be surveyed before starting work, and finding the exact location of one parcel survey in the case of on-site surveying and moving route. This is possible, and after the completion of the survey, it is possible to quickly and accurately plan the survey using drone images so that the status of the project area can be grasped and analyzed. suggest a way To this end, in addition to the digitizing method by adding a drone normal image that can grasp the outline of the land surveying reality boundary in the drone orthographic image, 3D drawing is performed to understand the more accurate one parcel surveying situation, and the survey navigation information is provided. can be produced In addition, it is used as basic data to compensate for errors in the next survey by comparing and analyzing the method of using the pre-information map for work during the actual one-lot survey and the difference between the prior information map and the actual one-lot survey performance after the survey work. This is possible.
