“…For the zero position difference, it can be calculated by taking photos of the square coordinates through the front and back mirrors, and then incorporating the formula to calculate the zero position difference. The measurement of shafting error is generally derived by spherical trigonometry principle [9].…”

Aiming at the problem that the traditional range optical measurement data processing software does not fully consider the characteristics of the observation equipment, which leads to the time-consuming and laborious data processing, a range optical measurement data processing and analysis system for range optical measurement data processing is designed and developed. The system includes image interpretation substation and data processing substation, and integrates multiple functional modules such as test image interpretation, data preprocessing, error correction, coordinate management, trajectory visualization display, multi station rendezvous, attitude measurement, velocity measurement, etc. The system adopts the architecture mode of front end and back end separation, realizes the front end and back end message communication through Web API, and realizes asynchronous data calculation and rendering display. User rights and role management are added to ensure the security and reliability of data storage.
