Embodiment Construction
[0036] Such as figure 1 A digital aerial photogrammetry method with ultra-high magnification magnification is shown. The aerial photographic image obtained after aerial photogrammetry of the survey area is an aerial image, and before the digital aerial photogrammetry with ultra-high magnification magnification, Carry out aerial photogrammetry on the survey area and obtain the aerial photographic image of the survey area, the aerial photographic image is a small-scale image; when actually performing digital aerial photogrammetry with ultra-high magnification and magnification, the following steps are included:
[0037] Step 1. Basic control survey: lay out multiple basic control points in the survey area, and establish a survey control network.
[0038] In this embodiment, when the basic control measurement is performed in step 1, the established measurement control network needs to conduct joint measurement with multiple high-level national control points near the measurement ...
