Atmospheric Disturbance Elimination Method Based on Camera System Design
This paper describes a method for eliminating atmospheric low frequency disturbances by designing a camera imaging system. Precision optical measurement engineering is usually performed outdoors, so it is difficult to avoid systematic errors caused by atmospheric disturbances. The atmospheric disturbance can be divided into two parts, i.e., high frequency disturbance and low frequency disturbance. The high frequency interference can be eliminated by image processing methods such as filtering. The optical measurement error caused by the atmospheric low frequency disturbance can be eliminated by establishing the constraint condition of the opposite view camera imaging system. We conduct an experiment with high-speed cameras to eliminate atmospheric disturbances, and use the planar mirror reflection imaging to complete the calibration of the camera system. Comparing the results of the experimental group and the control group, the measurement error is reduced from 2.99% to 0.35%. The results show that the camera imaging system has a good correction effect in the low frequency disturbance cancellation in the atmospheric disturbance.
