  • Publication number: 20260253240
    Abstract: Methods of measuring the depth of an object from two-dimensional images of the object. Such a method includes measuring first patch information from a first image in an image capture plane of an edge boundary of an object. The first image includes the edge boundary at a first state of defocus, and the first patch information includes boundaries, color, and blurriness of the first image. Second patch information is then measured from a second image in the image capture plane of the edge boundary. The second image includes the edge boundary at a second state of defocus, and the second patch information includes boundaries, color, and blurriness of the second image. A distance of the object from the image capture plane is then measured from differences in the first and second patch information based on differences of the edge boundary between the first and second states of defocus.
