High precision+Image+Mosaic+Method+in+Big+Frame+Measurement

1st International Symposium oil Systems and Control in Aerospace and Astronautics. Image mosaic is a very important step In big frame Image measurement,its precision has a great effeet on the measurement precision.twice matchim,gall make the mosaic suture precision beyond the pixel dimensions.And the pixeis’gray requirement rebuilding based on pixel position end pixel area distribufion ■lie has a great help to raise the measurement precision.
