POSITIONING AND ORIENTATION DATA ANALYSIS SYSTEM AND METHOD THEREOF

摘要

A positioning and orientation data analysis system for air vehicles includes an image sensor module, a positioning and orientation module, and a processor module. The image sensor module captures a map image of a region and has an internal direction parameter. The positioning and orientation module generates a positioning and orientation external direction parameter from external satellite positioning information and navigation coordinate information that it tracks. The processor module, which is electrically coupled to the image sensor module and the positioning and orientation module, generates an image external direction parameter by using aerial triangulation of the map image; and then, by comparing this parameter with the positioning and orientation external direction parameter, generates a boresight angle parameter and a lever arm parameter. The processor module then generates a first geographic location coordinate from these last two parameters, the internal direction parameter and another positioning and orientation external direction parameter.

1. A positioning and orientation data analysis system, applied to an air vehicle, comprising:
at least one image sensor module configured to capture a map image of a region, wherein the at least one image sensor module comprises an internal direction parameter; a positioning and orientation module configured to: receive external satellite positioning information; track a displacement of the air vehicle to generate navigation coordinate information; and generate a positioning and orientation external direction parameter from the external satellite positioning information and the navigation coordinate information; and a processor module electrically coupled to the at least one image sensor module and the positioning and orientation module, wherein the processor module is configured to: receive the map image; measure the map image to obtain an image external direction parameter; and generate a boresight angle parameter and a lever arm parameter by comparing the image external direction parameter and the positioning and orientation external direction parameter; wherein when the positioning and orientation module obtains a next positioning and orientation external direction parameter, the processor module calculates and generates a first geographic location coordinate from the internal direction parameter, the boresight angle parameter, the lever arm parameter and the next positioning and orientation external direction parameter.
