    Abstract

    Conclusions

    In this paper, we propose a laser far-field dynamic indication accuracy measurement method without reference distance using dual-perspective correction. First, we simplify the image registration process of the dual-imaging system and improve the image registration accuracy of the dual-camera imaging system for the registration standard deviation of 0.08 pixel. The actual registration standard deviation for a corresponding imaging distance at 1 km is 0.94 mm. Furthermore, we calibrate the dynamic measurement accuracy of the measurement system using a cooperative self-test lamp on the target plate by dual-perspective correction theoretical model without reference distance. The average measurement error of the measurement system is 2.45 mm with a dynamic measurement standard deviation of 9.90 mm. Finally, we perform practical dynamic indication accuracy tests of laser irradiation systems, to further verify the effectiveness of the proposed measurement method.
