The invention relates to a real-time three-dimensional reconstruction method based on an unmanned aerial vehicle image. The method solves the problems that an existing three-dimensional reconstructionmethod using an unmanned aerial vehicle cannot be carried out in real time and the time period is long. The method comprises steps of firstly, allowing the unmanned aerial vehicle to fly according toa preset route and a camera lens on the unmanned aerial vehicle to carry out data acquisition at three angles of 90 degrees, 30 degrees and 60 degrees; secondly, performing frame extraction on the collected video stream by a computer to obtain images of different surfaces of a target area, then performing image preprocessing, parameter preprocessing and camera calibration, then preparing a three-dimensional reconstruction environment, synthesizing a three-dimensional point cloud, and finally densifying the sparse point cloud through a Poisson algorithm, and attaching grids and textures to thesparse point cloud. The method is widely applied to the technical field of three-dimensional reconstruction.
Description
technical field [0001] The invention relates to the technical field of three-dimensional reconstruction, in particular to a real-time three-dimensional reconstruction method based on drone images. Background technique [0002] Three-dimensional reconstruction uses visual sensors such as cameras to acquire RGB images of different angles through image acquisition of the target area or object, so as to obtain a two-dimensional image of the target area or object. After a series of processing on the obtained image, the 3D model of the target area or object can be reconstructed. [0003] As we all know, the existing 3D reconstruction technology is based on the principle of photogrammetry. Ground control points are arranged on the ground, and photos are obtained by aerial photography of drones. The position information of the control points is measured by the GNSS receiver, and returned to Go to the ground, import aerial photos and location information into the computer, and then ...
