COORDINATE TRANSFORMATION METHOD AND APPARATUS FOR AERIAL PANORAMIC ROAMING DATA

摘要

Disclosed are a coordinate transformation method and apparatus for aerial panoramic roaming data. The method comprises: firstly acquiring N aerial panoramic roaming pictures photographed in an aerial photography region, and extracting longitude and latitude information of the N aerial panoramic roaming pictures; according to the longitude and latitude information of the ith aerial panoramic roaming picture and the longitude and latitude information of the first aerial panoramic roaming picture, in conjunction with a preset conversion method, obtaining converted longitude and latitude information corresponding to the ith aerial panoramic roaming picture, wherein N≥i>1; and according to the converted longitude and latitude information, the earth radius and a circumference ratio, obtaining a horizontal axis coordinate value and a longitudinal axis coordinate value corresponding to the ith aerial panoramic roaming picture. According to the technical solution of the present invention, longitude and latitude coordinates can be converted into plane coordinates without the need to acquire a large amount of parameter information, so that the efficiency of coordinate transformation is improved, and data storage space is reduced.
