The hottest event is about holding 1500 high-preci

  • Detail

Notice on holding practical training on "1:500 high precision real estate measurement and 3D modeling technology based on UAV tilt photography" notice on holding practical training on 1:500 high precision real estate measurement and 3D modeling technology based on UAV tilt photography, It is easy to learn and widely used in 1:500 large-scale topographic map survey, real estate survey, cadastral survey and other fields. It is a revolutionary new technology in the field of Surveying and mapping. Based on the current shortage of senior talents in the application of tilt photogrammetry technology, although the employees hold the practical training of 1:500 high-precision real estate surveying and 3D modeling technology based on UAV tilt photogrammetry at weekends, this training adopts the teaching method of UAV field flight and indoor data processing. Through field project training, they master the field flight of 1:500 large-scale UAV tilt photogrammetry and the layout of image control points, Three dimensional modeling technology, naked eye three-dimensional topographic map survey and real estate survey technology. The specific matters are notified as follows:
