光学仪器的使用,为人类测绘需求提供了更多可能。但是,光学仪器发展至今,仍旧有着不完善之处。例如由透镜所产生的中心偏,一直是影响测量精度的罪魁祸首。但是,鉴于物理性质不可背因素。光学测量已将中心偏引入到测量结果中,用于最终纠正测量所产生误差。因此,本文将以机械精度为核心,深入分析中心偏精度问题,并由此提供行之有效的解决方案。希望能够对我国光学测量事业的发展略尽一些绵薄之力。 The use of optical instruments provides more possibilities for human mapping needs. However, the development of optical instruments still has imperfections. For example, the central bias generated by the lens, has always been the culprit of the measurement accuracy. However, in view of the physical nature can not be a factor. Optical measurement has been introduced into the center of the measurement results, used to eventually correct the measurement error. Therefore, this article will focus on the mechanical precision, in-depth analysis of the center of precision, and thus provide effective solutions. Hoping to make some slight contributions to the development of optical measurement in our country.
