Hi Alexey,
Under Optimize Camera Alignment on p. 9 of the the linked tutorial (
PDF), it says "On the Reference pane uncheck all photos..." What is the reason for this? How does it optimize the camera alignment and the calibration if all the images are turned off? Or does this simply tell Photoscan not to use the GIS data associated with the images while continuing to perform bundle adjustments to optimize camera alignment?
Also, is it ok or not recommended to change any settings in the Reference Settings pane as the optimization proceeds? For example, after several iterations of Gradual Selection for Reprojection Uncertainty to remove selected points with higher errors, could one use a lower value for marker accuracy and tie point accuracy as the calibration proceeds? Another expert who teaches Photoscan has told me that the tie point accuracy of 4 seems very high and it should be possible to reduce this value to 0.5 or less (he typically sets this value at 0.1).
Thanks
