Why does Hugin consistently build results much smaller than the dimensions it gives me if I click "Calculate optimal size"?
My lens has an angle-of-view of 46 degrees (on the sensor) in the horizontal direction. I take 12 images per row. So of the 46 degrees captured per image, 30 degrees are needed to complete the pano. I believe this is approximately a 35% overlap. This tells me that of each image of the 12 that 65% of the pixels will end up being used (on average). My sensor in the horizontal direction is 2,592 pixels. My simple mind wants to believe that the resulting stitched image will be approximately 2,592 * 0.65 * 12 = 20,218 pixels. But Hugin generates a 13,250 x 6,625 result (or thereabouts). When I load an image-set and click on "Calculate optimal size" Hugin sets the Canvas Size to 19,450 x 9,725. It appears my math is consistent with what Hugin tells me the "optimal" size is. But without exception when a pano is complete the X dimension is in the low 13,000 range. Would someone kindly explain to me the reason for this difference? Thanks -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
