3D reconstruction method of single tower building based on tilt photography

Aiming at the failure of building three-dimensional model due to irregular shape of single tower building, a three-dimensional reconstruction method of tower single building based on inclined photography technology is proposed. First, the consumption type multi rotor unmanned aerial vehicle equipped with a single lens camera is selected to obtain the number of multi view images by loop shooting. Then, the multi view image data is processed by ContextCapture software to construct the real three-dimensional model of tower building. Finally, the accuracy of the generated three-dimensional model is evaluated by using the field control points and texture details. The experiment shows that; the loop line aerial photography used to obtains the multi view image data to construct the three-dimensional model has high accuracy, less missing texture information and high integrity.
