Research on the Influence of the Layout Method of Image Control Points on the Accuracy of Realistic 3D Model Results
In response to the lack of research on the impact mechanism of the layout method of image control points on the accuracy of three-dimensional models and aerotriangulation calculations, this article takes a certain 3D modeling flight mission for surveying and demarcation as an experimental case and sets up 9 image control point schemes. Subsequently, an in-depth study was conducted on the impact of image control point deployment schemes on the calculation and model accuracy of spatial data. Accuarcy statistics and validation were conducted on the 3D model results obtained from 9 image control point deployment schemes. The experimental results indicate that the statistical comparison and analysis of model point accuracy and edge length accuracy complying with relevant specifi-cations, and verify that as the number of image control points increases linearly, the model accuracy improves and tends to stabilize. The relevant research in the article can provide reference and guidance for the layout of image control points in relevant photogrammet-ric flight missions.
