摘　　要：详细分析了线阵影像外部和内部标定参数对像点定位误差的影响,基于线阵影像初始像方误差,有效分离并估算了外定标参数的常数项。设计了不同参数的检校实验,逐个解算各定标参数的数值,并验证了分析与判断结果。利用多景影像验证了内外定标参数解算结果的有效性和适用性。In this paper,we analyzed the effects of external and internal calibration parameters of linear push-broom camera on the positioning error of images in detail.Based on the initial image error of the experimental image data,we separated and estimated the constant term of the external calibration parameter.Then,we designed some calibration experiments for different parameters,and verified the analysis and judgment results.Finally,we used multi-image to verify the effectiveness and applicability of the internal and external calibration parameters.
