Machine Vision System Calibration

Abstract

Systems and methods for machine vision are disclosed herein. The machine vision system includes a motion rendering device, a first image sensor and a second image sensor. The machine vision system includes a processor configured to execute a computer program stored in memory, the program configured to determine a first transformation, which allows mapping between associated second coordinate systems, and determining a second transformation allowing mapping between said first coordinate system associated with said motion rendering device and a third coordinate system associated with said first image sensor .

[0001] Cross References to Related Applications [0002] This application claims the benefit under 35 U.S.C. §119(e) of Provisional Patent Application No. 62 / 199,459, entitled "Calibration of Machine Vision Systems," filed July 31, 2015, the entire contents of which are hereby incorporated by reference in their entirety . technical field [0003] The disclosed devices, systems, and computing methods relate generally to machine vision systems, and more specifically, to calibrating machine vision systems. Background technique [0004] In a machine vision system, one or more image capture devices may be utilized to perform vision system processing on objects or surfaces within an imaged scene. These processes may include inspection, imaging / symbol decoding, object alignment, and / or various other tasks. In some implementations, a machine vision system may be used to inspect workpieces disposed within or passing through an imaged scene. This scene can be imaged by one or more ...
