“…Therefore, before navigation, the LDV needs to be calibrated to determine the installation error angle and scale factor error between the LDV and IMU, so as to ensure the high precision of the LDV and navigation system. In 2018, Wang et al designed the LDV land navigation system configured by Janus and derived its calibration method [1][2][3] . In 2019, Huang et al designed a high-precision calibration system for reference beam LDV based on cylinder.…”
