Research on the three-dimensional terrain reconstruction system of Four-axis eight-rotor aircraft with binocular camera

In order to solve the problem of indoor 3D terrain reconstruction, a 3D terrain reconstruction system based on Four-axis eight-rotor aircraft with binocular camera is constructed. The binocular camera is a shooting tool similar to the human eye that can recognize the depth of field. It is planned to use a self-made four-axis eight-rotor UAV with a binocular camera as the hardware foundation of the system. The drone can achieve accurate indoor positioning by installing an optical flow module. The depth of field image is returned in real time indoors. The receiving end collects the depth of field image of the binocular backhaul, and uses an image stitching algorithm based on the phase correlation method to determine the similar area and adopts the feature point matching method to realize the automatic stitching of the image. The system can use Open CV to represent stitched images as images of depth of field rendered in different colors. The system is used to carry out 3D terrain reconstruction experiments. The results show that the 3D terrain reconstruction images obtained by the system meet the actual needs, which proves that the system has an ideal reconstruction effect on the indoor three-dimensional terrain.
