WebApr 19, 2024 · In traditional photogrammetry pipelines, self-calibrated bundle adjustment (SCBA) improves the BA accuracy by simultaneously refining the interior orientation parameters (IOPs), including lens distortion parameters, and the exterior orientation parameters (EOPs). WebSelf-calibrating bundle adjustment is performed with a minimum set of seven constraints, which are defined by the coordinates of three neighbor points and the RO constraints. The distance between two of these points must be accurately measured to define the scale of the photogrammetric network. After estimating the IOP, EOP and object ...
WebMar 19, 2024 · In the calibration process, the self-calibration bundle adjustment method was used. To evaluate the metric performances, the geometric accuracy tests in the image and object spaces were performed and the test results were compared. WebDec 11, 2013 · In this paper, a self-calibration bundle adjustment method is proposed to eliminate these effects by adding several parameters into the IO model and fitting EO parameters using a third-order polynomial. The additional IO parameters and the EO …
