Example Embodiment

[0036] figure 1 It is a block diagram of an exemplary machine vision inspection system 10 according to the present invention. The machine vision inspection system 10 includes a vision measuring machine 12 that is operatively connected to a control computer system 14 and exchanges data and control signals therewith. The control computer system 14 is also operatively connected to the monitor 16, printer 18, joystick 22, keyboard 24, and mouse 26 and exchanges data and control signals with them. The vision measuring machine 12 includes a movable workpiece measuring table 32 and an optical imaging system 34 which may include a zoom lens or an interchangeable lens. The zoom lens or interchangeable lens generally provides various magnifications for the image provided by the optical imaging system 34.

[0037] The joystick 22 can typically be used to control the movement of the movable workpiece measuring table 32 in the X and Y directions and the movement direction component of the mo...

Abstract

A precision machine vision inspection system and method for increased inspection throughput. The vision inspection system includes a movable stage for scanning and measuring selected workpiece features. In prior systems, conventional interspersing of image processing and inspection operations with image acquisition operations required stopping and starting the stage motion during image acquisition, necessitating associated delays or wait-states in various operations. Such delays are avoided in this invention by acquiring images continuously, with a timing that is independent of image inspection operations, so that delays and wait-states are avoided. In addition, continuous stage motion is combined with a strobe lighting feature during the image acquisition operations to acquire blur-free images at a high rate. Improved image acquisition and image analysis routines including these features are created and stored by the system.

Description

technical field [0001] The present invention generally relates to a method for operating a machine vision inspection system with a camera and a measurement table movable relative to each other in multiple directions to scan and inspect selected features of a workpiece on the measurement table, and more In particular, the present invention relates to systems and methods for programming and executing image acquisition operations independent of image inspection operations, and systems for performing image acquisition operations by using continuous motion for improved precision machine vision inspection system throughput and methods. Background technique [0002] Precision machine vision inspection systems can be utilized to obtain precise spatial measurements of inspected objects and to inspect various other object characteristics. Such a system may include a computer, camera and optical system, a precision measurement table that is movable in multiple directions to allow the ...
