1. A system configured to verity insertion of a wire contact into a wire contact insertion hole of a connector, wherein the system comprises:
at least one image acquisition device configured to acquire an image of a connector having a plurality of wire contact insertion holes; and
processing circuitry in communication with the at least one image acquisition device and configured to:
process images from the at least one image acquisition device;
identify a wire contact within a wire contact insertion hole of the plurality of wire contact insertion holes based on the images from the at least one image acquisition device;
obtain a wire contact insertion hole mask for the wire contact insertion hole;
adjust the wire contact insertion hole mask for the wire contact insertion hole;
apply adaptive thresholding to detect the wire contact within the wire contact insertion hole;
obtain a wire contact radius by obtaining a smallest circle that encircles the wire contact within the wire contact insertion hole; and
determine that the wire contact radius satisfies a wire contact radius threshold to establish that the wire contact is fully inserted into a correct wire contact insertion hole; and
provide feedback that indicates that the wire contact is inserted into the correct wire contact insertion hole.
