摘要
为了使测量设备快速进入测量状态,减小因倾斜带来的测量误差,结合工程实际应用,根据光学成像理论,利用水平倾角仪测量的角度值,建立了一个实时调平补偿的数学模型.根据不同的测量设备确定其补偿算法,可对测量设备在一定的倾角范围内倾斜时进行实时补偿,并进行了实验验证.实验结果表明,测量设备在倾角α=0.325°,β=0.896°倾斜情况下,经过实时补偿可将系统测量误差由0.126%提高到0.026%.
In order to make the measuring device quickly work and reduce the error of incline, based on project practicality and optics theory, a mathematical model for real-time compensative level is established using the angles tested by dipping compass. Different compensation algorithms are founded according to the specific parameters of measuring equipments, a real-time compensation program is carried out when the inclining angle is in a certain range, and it was verified by experiments. The result shows that the measurement precision is improved from 0. 126% to 0.026% after real-time compensation when the obliquities of measuring equipment is at α=0. 325° and β=0. 896°.
