Pix4D provides two main functions of compositing ground images and building elevation models with high accuracy, meeting strict standards for cartography.<\/p>\n\n\n\n In addition, Pix4D also builds 3D models, creates vivid fly-through animation videos that are very suitable for inspection and construction supervision. Pix4Dmapper software is currently being used by many organizations and companies in the geodetic industry to build applications to improve productivity and work efficiency.<\/p>\n\n\n\n The processing of ground images from drones includes three main input data sets:<\/p>\n\n\n\n Ground shots include images and photos taken from above by unmanned aerial vehicles. Each project of ground photography usually has the number of photos ranging from a few dozen to several thousand, depending on the size of the project and the accuracy requirements.<\/p>\n\n\n\n Ground control point is statically measured by GPS method.<\/p>\n\n\n\n The test plot is measured by the RTK method or the total station method. The inspection plan needs to have high accuracy and appropriate density of measurement points to ensure the quality of the ground image.<\/p>\n\n\n\n The use of drones for photography can be done manually or through an automated flight system.<\/p>\n\n\n\n Before flying, the scope of the project must be clearly defined in order to design a reasonable flight path. The scope of the flight path must cover the entire project scope.<\/p>\n\n\n\n Photos taken in succession always have a certain coverage. The coverage between successive images is at least 50% and as high as 85% depending on the job requirements and accuracy. The thicker the coverage, the higher the accuracy, the better the 3D model building, but the heavy input data and the more time consuming to process.<\/p>\n\n\n\n Control points of coordinates and ground elevation will be measured by static GPS measurement method. The control point must be evenly distributed throughout the measuring area.<\/p>\n\n\n\n Control points will be marked with ground targets. When conducting flight shooting, the ground targets will be clearly displayed on the image, helping the image manipulation and image processing to take place smoothly and the results will be highly accurate.<\/p>\n\n\n\n Image processing with Pix4D software includes three main steps:<\/p>\n\n\n\n As the first geodetic data processing platform founded and deployed in Vietnam, Auto Timelapse optimizes the features of current geodetic data processing platforms and upgrades it with automatic processing. Manage and display online data. <\/p>\n\n\n\n The technology automatically processes raw data: image centers, drone images, GCP, PPK points, .. into geodetic products: 2D geodetic maps, 3D models, VR360 images accurately and quickly.<\/p>\n\n\n\n Experience the SIMEXCO Buon Ma Thuot project<\/a> <\/strong><\/p>\n\n\n\n Offering a user-friendly experience, the Tracdiaso platform is designed with an easy-to-use interface. Geodetic work for current status measurement, surveying, mapping<\/a><\/strong> , site clearance, etc. is carried out simply and quickly. The digital geodetic platform supports online data storage, display, and analysis.<\/p>\n\n\n\nLearn about Pix4Dmapper software in geodetic data processing<\/span><\/h2>\n\n\n\n
