摘要
探讨的是景深大小对于2.5D影像测量仪Z轴测量精度的影响。通过理论数据的推导以及具体实验的设计,告诉测量者要改变焦距和放大倍率来控制景深的大小,从而得到准确测量结果。对二维半测量工作具有显著指导意义。
This paper explores the influence of field depth on the Z-axis measurement accuracy of the 2.5D image measuring instrument.Through theoretical derivation of data and detailed experimental design,It is concluded that the field depth can be controlled by changing the focal length and magnification to obtain accurate measurement results.This paper has guiding significance for the two and half dimeusion measurement.
