摘　　要：提出了一种基于数字摄影测量技术的火炮质心高度测量方法。该方法将数字摄影测量技术和悬挂法结合使用,根据吊点垂线的延长线通过悬挂物质心原理进行质心高度测量。采用数字摄影测量技术精确获取在火炮三维坐标系下火炮和铅垂线上粘贴的测量标志空间三维坐标,在2种不同悬吊姿态下利用铅垂线上测量标志三维坐标拟合得到铅垂线方程,联立两条铅垂线方程确定火炮质心高度坐标。对该测量方法进行了试验验证及误差分析,验证了该方法的可行性。A method for measuring the height of the artillery center of mass based on digital photogrammetry technology was proposed in this research.Combining digital photogrammetry technology with suspension method,this research measured the height of the center of mass based on the theory that the extension of the vertical line of the suspension point goes through the center of mass suspended.Digital photogrammetry technology was used to accurately obtain the three-dimensional coordinates of the measurement marks pasted on the artillery and the plumb line in the artillery three-dimensional coordinate system.The plumb line was obtained by fitting the three-dimensional coordinates of the measurement marks on the plumb line under two different suspension postures Equation.Two plumb line equations were combined to determine the height coordinate of the artillery center of mass.Error analysis of the measurement method was carried out,and the feasibility of the method was verified.
