Abstract: Measuring accuracy of inclinometer based on accelerometer is mainly influenced by the adopted accelerometer sensor. To improve the measuring accuracy of the inclinometer, the structure of the measuring system is given and measuring principle is analyzed, and the error model is established in this paper. Furthermore, the model is verified by simulation and experiment, which not only gives the smallest errors of the measured pitch and roll, but also lays foundation for sensor selection, error analysis and error compensation. The results show that the error model is of practical value.
