Attitude angle measurement system based on photoelectric collimation principle is established. A virtual extended imaging plane technology is proposed. It is used in the measurement system to multiplex the image sensor imaging plane and virtually expand the measurement field of view of the system. The main working principle of the system is introduced. Under the system model, the error sources that may affect the measurement accuracy of the system are analyzed, the mathematical relationship between them is established, and the quantitative simulation experiments are carried out on the influencing factors of the accuracy. According to the simulation results, the system design is analyzed and verified. The results show that the factors of analysis have an impact on the measurement accuracy of the attitude angle of the system, and the methods and ways of reducing the system error and improving the measurement accuracy can be determined by taking the analysis results as reference.
