AI Technical Summary

Problems solved by technology

However, the cost of surveying and remote sensing measurement of actual terrain is high, and it is difficult for most research institutions and individuals to complete scientific research work that requires the participation of actual terrain, nor can it meet the needs of scientific experiments for some customized experiments, such as: Using the solid three-dimensional terrain surface model with known resolution (or accuracy), through the establishment of remote sensing stereo imaging (or measurement) half-in-the-loop simulation test system, quantitatively study the imaging system parameters, orbit parameters and attitude parameters and other factors for remote sensing stereo imaging (or measurement) The mathematical model of the influence of measurement) accuracy

[0003] However, the 3D digital terrain model is only a 3D visualization of the actual terrain, stored in the computer in the form of digital data, and cannot be applied to physical or semi-physical simulation systems that require the participation of the actual terrain model

At the same time, due to the inherent processing error of the processing system, the real 3D coordinate data of the processed solid 3D terrain model is unknown
