Large Space Camera Calibration for Three-Dimensional Videogrammetric Vibration Measurement of Large Aeroplane Model in Wind Tunnels[J]. 2009, 43(3): 55-59.DOI:
To realize three-dimensional videogrammetric vibration measurement of large aeroplane model in wind tunnels
a new large space camera calibration arithmetic is proposed
which considers the calibration board error in manufacture. The initialize calibration result by Zhang Zhengyou calibration arithmetic is optimized by bundle adjustment of the digital close range industry photogrammetry. There are two coefficients of the radial symmetrical distortion for the lens in Zhang zhenyou's method. The error from radially symmetrical
radial asymmetrical and tangential distortions for the lens is eliminated in this method. The experiment show that the precision of this new arithmetic is exceeding of 1/5 000
and the error is only 27% of Zhang Zhengyou calibration arithmetic. The large space camera calibration is achieved with this new calibration arithmetic
which enables to suit the requirements for videogrammetric vibration measurement of large aeroplane model in wind tunnels.
