Coordinate Conversions and Deviation Analysis in Multi-source Data Fusion

Coordinate transformation is widely used in the field of multi-source data fusion and affects final data accuracy. In order to establish the propagation model of measured deviation in the coordinate system conversion process in the process of multi-source data fusion using multiple sensor data, the deviation transfer model is mainly explained from two aspects: the conversion of sensor measurement data between different coordinate systems and the transfer process of measured deviation between coordinate systems. Finally, summarize and analyze the relationship between the factors affecting the measured deviation transmission.
