Optimizing capture of focus stacks |
摘要 |
Generating a focus stack, including receiving initial focus data that identifies a plurality of target depths, positioning a lens at a first position to capture a first image at a first target depth of the plurality of target depths, determining, in response to capturing the first image and prior to capturing additional images, a sharpness metric for the first image, capturing, in response to determining that the sharpness metric for the first image is an unacceptable value, a second image at a second position based on the sharpness metric, wherein the second position is not included in the plurality of target depths, determining that a sharpness metric for the second image is an acceptable value, and generating a focus stack using the second image. |

1. A method of generating a focus stack, comprising:
receiving initial focus data that identifies a plurality of target depths; positioning a lens at a first position to capture a first image at a first target depth of the plurality of target depths;
determining, in response to capturing the first image and prior to capturing additional images, a sharpness metric for the first image;capturing, in response to determining that the sharpness metric for the first image is an unacceptable value, a second image at a second position based on the sharpness metric, wherein the second position is not included in the plurality of target depths;determining that a sharpness metric for the second image is an acceptable value; andgenerating a focus stack using the second image. |
