AI Technical Summary

Technical Problem

When faced with vehicle body swaying and turret rotation, the vehicle-mounted moving base photoelectric detection turntable causes changes in the line of sight, affecting tracking accuracy and stability, and network latency causes instability in the photoelectric servo system.

Method used

By calculating the three-axis angular changes of the carrier relative to the geographic coordinate system, the required turntable reverse drive angle to eliminate carrier sway is calculated, and a UTC timestamp is added to the photoelectric servo control system to eliminate network latency.

Benefits of technology

Accurately tracks targets even when the carrier is shaking, improving the stability and tracking accuracy of the photoelectric servo system.

Abstract

This invention discloses a servo control method and device for a vehicle-mounted moving-base photoelectric detection turntable. The method includes: determining the target direction of the turntable based on control commands, and calculating the control quantity required for the turntable to reach the target direction based on a preset algorithm; acquiring the three-axis angular changes of the vehicle relative to the geographic coordinate system, including roll angle, pitch angle, and yaw angle; calculating the turntable reverse drive angle required to eliminate vehicle swaying based on the target direction and the three-axis angular changes, including azimuth angle and pitch angle; and adding a UTC timestamp to the photoelectric servo control system to eliminate network delay between the photoelectric servo control system and the photoelectric system. This application can accurately track targets even when the vehicle is swaying, exhibiting high stability.
