Выравнивание изображения / Image alignment

The image alignment task provides the ability to adjust overall alignment between one image and the next.

Refer to “Manually aligning images” in Chapter 6, “Correcting stitching problems” for step-by-step instructions.

Просмотр перекрытия / View overlap

Смешение / Blend — Select this option to show the overlap region normally, as a blend of the two images.

Сравнение / Compare — Select this option to highlight differences between the images in the overlap region.  A medium gray color is shown when the images match exactly.  Brighter or darker colors indicate mismatches between the images.

Подогнать изображение / Adjust image
Use the arrow buttons to move the right hand image relative to the left hand image.  Individual clicks on the buttons move the image by single pixels.  Holding a button down causes the image to move continuously.  If you hold the button for a long time, the motion accelerates.

Корректировка фокусного расстояния & бочкообразных искажений / Focal length & barrel correction

The focal length and barrel correction task provides the ability to interactively adjust the focal length and barrel correction settings.

Refer to “Adjusting focal length and barrel correction” in Chapter 6, “Correcting stitching problems” for step-by-step instructions.

Просмотр перекрытия / View overlap

Смешение / Blend — Select this option to show the overlap region normally, as a blend of the two images.

Сравнение / Compare — Select this option to highlight differences between the images in the overlap region.  A medium gray color is shown when the images match exactly.  Brighter or darker colors indicate mismatches between the images.

Фокусное расстояние / Focal length
Enter the focal length of the lens in millimeters.  This may be the actual focal length of the lens or the 35mm equivalent focal length, depending upon the options you selected on Wizard step 3/9 – Опишите вашу камеру / Describe your camera or the Свойства Камеры / Camera properties dialog box.

You can click the up and down arrows to adjust the focal length value by small steps.  Holding a button down continuously adjusts the value.  If you hold the button for a long time, the adjustment accelerates.

NOTE: The focal length setting applies to all overlap regions in your panorama and may slightly affect the image-to-image alignment.  You should check the alignment in each overlap region after changing this setting.

Уточнить ±50% / Refine ±50%
Select this button to refine the focal length setting based upon the current pair of images at their current relative alignment.  You may get erratic results if the overall image alignment is incorrect, so adjust overall alignment before refining focal length.

Коррекция бочкообразности / Correct barrel distortion
If your camera and lens combination exhibit barrel (or pincushion) distortion, you can use this value to correct it.  Use small negative numbers (-0.05 is a large correction) to correct barrel distortion.  Use small positive numbers (0.05 is a large correction) to correct pincushion distortion. To disable the correction, enter zero.

You can click the up and down arrows to adjust the focal length value by small steps.  Holding a button down continuously adjusts the value.  If you hold the button for a long time, the adjustment accelerates.

NOTE: The correction for barrel distortion applies to all overlap regions in your panorama and may slightly affect the image-to-image alignment.  You should check the alignment in each overlap region after changing this setting.

NOTE:  Correcting barrel distortion will increase the time required to compute your panorama.

Уточнить с фокусным расстоянием / Refine with focal length
If you select this checkbox, the barrel correction will be refined with the focal length when you select the Уточнить ±50% / Refine ±50% button.

Enter the focal length of the lens in millimeters.  This may be the actual focal length of the lens or the 35mm equivalent focal length, depending upon the options you selected on Wizard step 3/9 – Опишите вашу камеру / Describe your camera or the Свойства Камеры / Camera properties dialog box.

Точная подгонка / Fine tuning

The fine tuning task provides the ability to make small-scale adjustments to correct for local mismatches in the image alignment.

Refer to “Fine tuning the image alignment” in Chapter 6, “Correcting stitching problems” for step-by-step instructions.

Просмотр перекрытия / View overlap

Смешение / Blend — Select this option to show the overlap region normally, as a blend of the two images.

Сравнение / Compare — Select this option to highlight differences between the images in the overlap region.  A medium gray color is shown when the images match exactly.  Brighter or darker colors indicate mismatches between the images.

Настроить ячейку точной подгонки / Adjust tile
Use the arrow buttons to move the right hand image relative to the left hand image within the selected fine tuning tile.

Individual clicks on the buttons move the image by single pixels.  Holding a button down causes the image to move continuously.  If you hold the button for a long time, the motion accelerates.

Автоматическая точная подгонка / Auto fine tune
Use this button to discard the fine tuning of the current overlap region and then automatically fine tune the region.

Сбросить точную подгонку / Clear fine tuning
Use this button to discard the fine tuning of the current overlap region.

Корректировка экспозиции & падения яркости / Exposure & falloff correction

The exposure and falloff correction task provides the ability to adjust exposure matching between one image and the next and the brightness falloff correction.

Refer to “Fine tuning the image alignment” in Chapter 6, “Correcting stitching problems” for step-by-step instructions.

<--- Яркость / Brightness --->
Use this slider to adjust the exposure matching between adjacent images.  Moving the slider to the left increases the brightness of the lefthand image (or decreases the brightness of the righthand image).  Moving the slider to the right increases the brightness of the righthand image (or decreases the brightness of the lefthand image).

Коррекция падения яркости / Correct brightness falloff
If your camera and lens combination exhibit brightness falloff in the corners you can use these values to correct it.

Величина / Amount — The brightness falloff factor in the extreme corners of the image.  The value represents the brightness in the corner of the image relative to the center of the image.  For example, a value of 0.1 means that the brightness has fallen off by one tenth (i.e. to 90% brightness) in the corner.

Размер / Size — The spread of the falloff outward from the corners of the image.  The value represents the distance from the corner at which the falloff reaches approximately 50% of its maximum.  For example, a value of 0.1 means that the brightness falloff is at 50% of the maximum falloff at about one tenth the distance from the corners to the center.

NOTE:  Correcting brightness falloff will increase the time required to compute your panorama.

NOTE: The brightness falloff correction applies to all overlap regions in your panorama.  You should check each overlap region after changing this setting.
