US 12,126,945 B2 · Focus identification method and focus identification system thereof

Abstract

A focus identification method adaptable for a focus identification system is provided. The focus identification method includes: capturing a projection picture to generate a captured picture; dividing the captured picture into a plurality of image regions; calculating a plurality of sharpness values corresponding to the plurality of image regions respectively according to image data of the plurality of image regions; and displaying the plurality of sharpness values on the projection picture corresponding to the plurality of image regions respectively the to generate a first focus identification picture. Moreover, the disclosure further discloses a focus identification system applying the focus identification method. The focus identification method and the focus identification system using the same in the disclosure may improve the remote maintenance efficiency.

Dependent claims

A focus identification method, adaptable for a focus identification system, the focus identification method comprising:

capturing a projection picture projected by a projection device from a projection target to generate a captured picture, wherein the projection picture comprises an identification pattern;
dividing the captured picture into a plurality of image regions corresponding to the projection picture;
calculating a plurality of sharpness values corresponding to the plurality of image regions respectively by a processor according to image data of the plurality of image regions;
and
generating a first focus identification picture by the processor, wherein the first focus identification picture has the plurality of sharpness values on the projection picture corresponding to the plurality of image regions of the captured picture respectively, wherein the plurality of sharpness values of the first focus identification picture correspond to the identification pattern of the projection picture.

2 more elements

A focus identification system, comprising:

a projection device, configured to project a projection picture to a projection target;
an image capturing device, coupled to the projection device, configured to capture the projection picture on the projection target from the projection target to generate a captured picture, wherein the projection picture comprises an identification pattern;
a processor, coupled to the projection device and the image capturing device, configured to divide the captured picture into a plurality of image regions corresponding to the projection picture, and calculate a plurality of sharpness values corresponding to the plurality of image regions respectively according to image data of the plurality of image regions, and generate a first focus identification picture, wherein the first focus identification picture has the plurality of sharpness values on the projection picture corresponding to the plurality of image regions of the captured picture respectively, wherein the plurality of sharpness values of the first focus identification picture correspond to the identification pattern of the projection picture.
