Abstract
A marker image detection section detects a marker image from a captured image for determining a defocus amount. A discriminator discriminates the defocus amount of the marker image included in the captured image. The discriminator performs learning using feature amounts related to a plurality of teacher marker images captured with various defocus amounts and discriminates a defocus amount of an input marker image.
Claims13
A defocus amount measuring device comprising at least one processor, wherein the processor is configured to:
- detect a marker image from a captured image acquired by imaging a marker that is a measurement target of a defocus amount;
- and
- discriminate a defocus amount of an input marker image by a discriminator that performs learning using feature amounts related to a plurality of teacher marker images captured with various defocus amounts.
A defocus amount measuring method comprising:
- detecting a marker image from a captured image acquired by imaging a marker that is a measurement target of a defocus amount;
- and
- discriminating, using a discriminator that performs learning using feature amounts related to a plurality of teacher marker images captured with various defocus amounts and that discriminates a defocus amount of an input marker image, the defocus amount of the input marker image.
A non-transitory computer-readable storage medium that stores a defocus amount measuring program causing a computer to execute:
- a process of detecting a marker image from a captured image acquired by imaging a marker that is a measurement target of a defocus amount;
- and
- a process of discriminating, using a discriminator that performs learning using feature amounts related to a plurality of teacher marker images captured with various defocus amounts and that discriminates a defocus amount of an input marker image, the defocus amount of the input marker image.
A discriminator that performs learning using feature amounts related to a plurality of teacher marker images captured with various defocus amounts and discriminates a defocus amount of an input marker image.
A defocus amount measuring device comprising:
- a discriminator that performs learning using feature amounts related to a plurality of teacher marker images captured with various defocus amounts and in a case where a captured image acquired by imaging a marker that is a measurement target of a defocus amount is input, discriminates a presence or absence of a marker image in the captured image and a defocus amount of the marker image in a case where the marker image is included in the captured image.
A discriminator that performs learning using feature amounts related to a plurality of teacher marker images captured with various defocus amounts and in a case where a captured image acquired by imaging a marker that is a measurement target of a defocus amount is input, discriminates a presence or absence of a marker image in the captured image and a defocus amount of the marker image in a case where the marker image is included in the captured image.
