AI Technical Summary
In existing technologies, it is difficult to locate thermal images of different ranges at the same reference position during aero-engine testing, resulting in data offset and splicing misalignment, which affects data accuracy and efficiency.
A triangular right pyramidal heat source array is constructed and used as a reference system. The offset between thermal images of different ranges is determined by calculating the horizontal azimuth and elevation angles. The center point coordinates at the pixel level are calculated and stitched together based on the heat source array.
It enables precise positioning and rapid stitching of thermal images with different ranges, improving the accuracy and efficiency of data processing and reducing random errors.
