Dynamic Error Analysis and Compensation of Multi-station Measurement Network for Space GNC Simulation
- As a core supporting technology of aerospace GNC simulation, the dynamic measurement capability of wMPS multi-station network is the focal point of space GNC physical simulation laboratory (Tianjin)'s follow-up construction. The aims of this project will contain mechanism analysis, dynamic error transfer model construction, the time-driven transmitter angle data stream processing algorithm, and the final goal is to achieve accurate multi-station measurement information synchronization and improve the dynamic measurement accuracy of wMPS (indoor GPS) system.
Novel Method for Dynamic Measurement of Large-scale 3-D Shape Based on 1-D Image sequence
- In view of the completeness and comprehensiveness of 3-D shape information, 3-D shape measurement has shown its important application value and increasing prospect in fields of large-equipment operation control, facility fault detection and condition monitoring. To meet the special requirements of large scale, high dynamic and high resolution on 3-D shape measurement in these areas, by utilizing the feature of high speed relative motion between sensor and measured object, and borrowing the idea of high resolution terrain mapping in aerospace, high-speed linear CCD image sensor is introduced into large-scale spatial 3-D shape measurement. Movement informations represented by speed are imported into existing 3-D shape measurement theory. Temporal relationship between 1-D image sequence and relative motion's position/orientation is established via global clock synchronization, then real-time estimation of the relative position/orientation is achieved during measurement process. On this basis, taking motion information as a reference, the image sequence registration and fusion are further studied as well as real-time 3-D reconstruction algorithm, and the error propagation pattern in 3-D shape measurement is also analyzed systematically. A running status monitoring and fault identification system for high-speed trains is set up to verify the new method. In this research, new ideas and new technologies can be produced for future applications such as dynamic measurement and 3-D state detection of high-speed rail trains.
