Xiaofang Kong, Qian Chen, Jiajie Wang, Guohua Gu, Pengcheng Wang, Weixian Qian, Kan Ren, Xiaotao Miao
2018 Sensors  
Section 3 explains inclinometer assembly error in photoelectric measurement systems. Section 4 introduces the proposed calibration and horizontal image correction method based on plumb lines.  ...  In order to solve the problem of the lack of complete attitude information in the measurement system, this paper proposes a new inclinometer assembly error calibration and horizontal image correction method  ...  Inclinometer Assembly Error Calibration and Horizontal Image Correction The inclinometer can only measure angles between two axes (x-axis and y-axis) and the horizontal plane.  ...
