Pix4D, together with Aeryon Labs Inc. and PUC University of Rio de Janeiro, reconstructed the first accurate 3D model of Brazilâs most important monument: the Christ the Redeemer statue in Rio de Janeiro. Using the Aeryon UAV platform for data acquisition and Pix4Dâs image processing software for the 3D reconstruction, the project team surmounted various challenges to acquire the high-resolution images needed for the model. The main challenges were the changing weather and wind conditions, restricted hours for data acquisition and inconsistent lighting conditions. A total of 3584 images were acquired and 2090 images were used in Pix4Dmapper Pro desktop software to convert them into the 3D model. The reconstruction was divided into three main projects (statue, base and surrounding area) to help manage the variations in image capture. A linear measurement, taken onsite by the project team, was used to provide the correct scale for the final result. www.pix4d.com www.aeryon.com
