Systems and methods for machine vision calibration

Abstract

A machine vision system for calibrating and/or positioning of various motion control modules of an opto-fluidic instrument/tool/instrument having integrated optics and fluidics modules configured for imaging of biological specimens is disclosed. The machine vision system includes determining 3D positions of an object within a reference coordinate system based on a plurality of stereo-images comprising the object; generating a transformation matrix based on the determined 3D positions of the object with respect to a reference position; and calibrating one or more motion control systems based on the determined transformation matrix. The methods also include determining a 3D position of an object within a reference coordinate system based on a stereo-image of the object; generating a 3D offset value between the determined 3D position and a reference location of the object; updating the 3D position using the 3D offset value; and positioning the object based on the corrected 3D position.
