地面激光扫描球形标靶的球心误差研究

Spherical Center Error of Sphere Target in TLS

    摘要
  • 摘要: 分析了球形标靶的特点,通过激光雷达方程描述了球心误差的产生过程和性质,研究统计了球心误差随激光入射方向的分布,采取多项式拟合和模拟球面的方法确定了球心位置和误差大小。实测数据验证了球心误差的系统性特点,并提出削弱球心误差的方法。

     

    Abstract: The trait of sphere target is analyzed,the generating process and characteristic of spherical center error are described by laser radar equation.The distribution of spherical center error with laser incident direction is researched and counted,and then determined by polynomial fitting model and simulation of sphere surface.The systematic characteristic of spherical center error is verified by the measured data and a weakening method is proposed.
