The three-dimensional point orientation of the target object and the transmission line is determined using the mapping relationship between two and three dimensions, the obtained data are calculated, and the calculation results are produced. In this study, the two-dimensional information is obtained by photographing the real-time panorama of the transmission line channel using a 3D camera, and the three-dimensional information is acquired using laser radar technology. However, the accuracy is very often unstable and dependent on the radiometric quality of images and the efficiency of the image processing technique. The most advanced of such imaging systems can create dense point clouds. In recent years, there has been a significant advancement in visualization techniques for power lines using unmanned aerial vehicle (UAV) platform photography. This increases the need for the implementation of advanced processing techniques. More and more data are being obtained via photogrammetric measurements.
Many remotely sensed data products like light detection and ranging (LiDAR) have been examined for power line surveys. Output formats: GeoTIFF, xyz, ASPRS LAS, Google KMZ / KML, COLLADA, VRML, OBJ, PLY, 3DS, FBX, Universal 3D, PDF, etc.Three-dimensional (3D) mapping of power lines is essential for power line inspection. Input formats: JPEG, TIFF, PNG, BMP, JPEG Multi-Picture Format (MPO). Processing of images is fully automated and requires no camera calibration or manual labeling of photos. If the program to enter the coordinates of at least 3 points on the object, or 3 point shooting, PhotoScan automatically attaches the model to a given coordinate system, allows us to calculate the projection of the model on a given surface ( orthophoto ), DEM relative to a given surface (DEM), and save orthophoto DEM in various coordinate systems and formats. If the program enter at least one distance between the object and shooting positions, PhotoScan restores the scale of the entire model and allows you to define the distance between any two points of the object and calculate the area and volume of the object or its parts.
The main thing is that each element of the reconstructed object was seen at least two positions taken.
PhotoScan capable of handling any photos taken with any digital camera, from any angle. Reinstated textured 3D model can be saved in various formats - OBJ, 3DS, PLY, FBX, VRML, COLLADA, U3D, PDF. For the reconstruction of the object in PhotoScan enough upload photos, no additional information is required.
