Photogrammetric system accuracy estimation by simulation modelling

In this work we developed a simulation model for spatial coordinates estimation in a photogrammetric system. We analyzed how the initial measurement errors of pixel coordinates on the sensor of a digital camera and the scene geometry influence the result errors of the 3D coordinates measured by the photogrammetric system. Our findings demonstrate the expected system's accuracy for industrial applications and theoretically confirm our previous experimental accuracy estimation. They also provide valuable information for further development of the photogrammetric system.
