基于坐标转换的炮兵观测器材倾斜修正模型

Tilt Correction Model of Artillery Observation Equipment Based on Coordinate Conversion

针对传统炮兵观测器材调平过程中存在的诸多不足,提出一种基于三维直角坐标转换的可对炮兵观测器材因倾斜造成的测量误差进行修正的模型。根据方向盘结构和瞄准点法赋予基准射向的特点确定合适的角度测量参数,建立器材坐标系和大地坐标系,再进行坐标转换,得出倾斜修正模型。分别用MATLAB和Keil C51编写了倾斜修正程序,通过算例将程序计算结果和Solidworks模型测量结果进行比较,验证了模型的正确性和实用性。

In view of the leveling deficiency in using the traditional artillery observation equipment, a model is put forward based on the three-dimensional rectangular coordinate conversion to correct the tilt. Measuring parameters are determined according to the features of the magnetic compass director’ s structure and aiming point method of giving reference direction. Then equipment coordinate system and earth coordinate system are established. Finally, the tilt correction model is built using coordinate con-verse. Tilt correction program is written with MATLAB and Keil C51. The calculated results of the pro-gram coincide with the measurement results of the mechanical model established in Solidworks through comparison, which proves the correctness and practicability of the model.
