Component concentricity
First Claim
Patent Images
1. A method for determining concentricity of a camera mounted within an aperture of an electronic device housing, the method comprising:
- obtaining an image of a camera mounted within the aperture of the housing;
identifying a plurality of circular shapes within the image using a processor;
determining an offset between two of the plurality of circular shapes, wherein one of the circular shapes comprises the aperture in the housing and the other circular shape represents the camera, by;
determining a maximum distance between edges of the two circular shapes;
determining a minimum distance between edges of the two circular shapes; and
calculating a ratio of the maximum and minimum distances.

Abstract
System and methods for determining a concentricity of a component mounted within an aperture of an electronic device housing. In particular, a method for determining concentricity of a camera includes obtaining an image of a camera mounted within the aperture of the housing and identifying a plurality of circular shapes within the image using a processor. One of the circular shapes represents the aperture in the housing and the other circular shape represents the camera. An offset between two of the plurality of circular shapes is calculated.

7. A method for determining a concentricity of a camera comprising:
-
capturing an image of a camera mounted within an aperture of a housing; providing the image to a processor for processing; discerning an edge of an outer circular shape; discerning an edge of an inner circular shape, the inner circular shape circumscribed by the outer circular shape; and computing a concentricity value of the inner circular shape relative to the outer circular shape by computing a ratio of a maximum distance and a minimum distance from the edge of the inner cicular shape and the edge of the outer circular shape. - View Dependent Claims (8, 9)

10. A method for determining concentricity of a camera mounted within an aperture of an electronic device housing, the method comprising:
-
obtaining an image of a camera mounted within the aperture of the housing; identifying an aperture circular shape within the image, representing the aperture in the housing, including identifying an aperture set of pixels that includes each pixel within the aperture circular shape; identifying a camera circular shape within the image, representing the camera, including identifying a camera set of pixels that includes each pixel within the camera circular shape; calculating an aperture centroid by; averaging the rows of the aperture set of pixels; and averaging the columns of the aperture set of pixels; calculating a camera centroid by; averaging the rows of the camera set of pixels; and averaging the columns of the camera set of pixels; determining an offset between the aperture circular shape and the camera circular shape from the aperture centroid and the camera centroid. - View Dependent Claims (11, 12, 13)
