Abstract
A socket testing method comprises obtaining a raw socket image, performing binarization on the raw socket image to generate a binarized socket image, determining a plurality of pinhead locations in the binarized socket image, applying a grid with the grid including a plurality of intersections to the binarized socket image, for each of the plurality of pinhead locations, obtaining the distance between the pinhead location and one of the plurality of intersections which is nearest to the pinhead location, and outputting a warning signal associated with the pinhead location when determining that the distance is larger than a tolerance value.
Claims9
A socket testing method, comprising:
- obtaining a raw socket image;
- performing binarization on the raw socket image to generate a binarized socket image;
- determining a plurality of pinhead locations in the binarized socket image;
- applying a grid to the binarized socket image, with the grid including a plurality of intersections;
- for each of the plurality of pinhead locations, obtaining a distance between the pinhead location and one of the plurality of intersections which is nearest to the pinhead location;
- and
- outputting a warning signal associated with the pinhead location when determining that the distance is larger than a tolerance value.
A socket testing system, comprising:
- a light assembly configured to illuminate a socket;
- an image sensor configured to obtain a raw socket image of the socket;
- and
- a processor connected with the light assembly and the image sensor, and configured to perform binarization on the raw socket image for generating a binarized socket image, to determine a plurality of pinhead locations in the binarized socket image, to apply a grid including a plurality of intersections to the binarized socket image, to obtain a distance between each of the plurality of pinhead locations and one of the plurality of intersections which is nearest to the pinhead location, and to output a warning signal associated with the pinhead location when determining the distance is larger than a tolerance value.
