摘要
近景三维目标测量系统要求达到厘米级的定位精度,GPS姿态测量的精度直接影响到整个三维测量系统的精度。本文在介绍最小二乘曲线拟合原理的基础上,采用二元多项式对姿态参数进行平滑拟合,以实例验证了此方法的有效性。
In the close shot target three-dimension survey system （3D-Sur）, the orientation precision is required to centimeter. The system＇ s accuracy precision is directly affected by that of GPS attitude. Based on introducing the principles of the least square conic fitting, this paper uses binary polynomial fitting for the attitude parameters. And an example has proved that this method is useful.
