| Abstract: | In order to improve the measurement efficiency of urban space，the single-lens-based drone tilt photogrammetry method and its accuracy were studied，the basic principles of tilt photography were analyzed，and a single-lens drone tilt measurement program was designed，mainly including drones.Model selection，image acquisition process，UAV flight parameters and aerial photography program design，and field measurement researched the accuracy of single-lens UAV tilt photogrammetry.The study concluded that the plane accuracy error of single-lens UAV tilt photogrammetry was generally 0~0.3 m，which met the requirements of the "Three-dimensional Geographic Information Model Data Product Specification"（CH T9015—2012）. |
