A method is provided for converting joystick deflection into a speed of relative motion between a image system and a workpiece stage in a computer vision system. The conversion of joystick deflection into speed may be described in terms of a speed/deflection profile that corresponds a present lens characteristics of the system. In one embodiment, the speed/deflection response of the system depends relatively strongly on the present lens characteristic at relatively lower deflections and depends on relatively weakly on the present lens characteristic as the deflection approaches a maximum deflection. The system is advantageous in that, for any lens used, it maintains consistent ergonomic and visual feel at small joystick deflections which typically occur during ostensible precision maneuvers, but is also able to provide fast long-range traverses for large joystick deflections.

A networking system includes telephone switches and data network gateways for routing calls either over the public telephone network or over the packet switched data network. A router examines initiated calls and selects either the telephone network or a data network for completing the call. A Network Operations Center (NOC) monitors the performance of plural gateways, and updates routing information in the router and/or in the gateways, which may be used for future calls.

A machine vision inspection system and method for generating a workpiece image acquisition/inspection program, which can be shared by different machine vision systems having different hardware capabilities. Each system includes a movable stage for scanning and measuring selected workpiece features, and preferably includes strobe lighting to control the effective exposure time of the workpiece image. The program provides for the determination of various image acquisition parameters, such as the stage velocity, strobe light power, strobe exposure time, etc., based on a functional limit related to image smear. Thus, the program automatically adapts to any specific system, by allowing determination of optimal image acquisition parameters for that system based on the functional limit. Accordingly, the same program is usable on different systems to consistently provide a desired level of accuracy as well as optimum or near-optimum throughput, regardless of which vision system is used.

The repeatability of strobe illumination for image exposure is improved over a wide dynamic range in a machine vision system wherein a relationship between a camera integration period and a pulse duration of a strobe light generator control the effective exposure of a camera image during a timing overlap between a beginning of the camera integration period and an end of the pulse duration. To avoid noise in the illumination, the illumination pulse duration may start, the camera integration period may begin after a delay relative to that start and not later than the end of the pulse duration, the pulse duration may end, and the camera integration period may end not earlier than the end of the pulse duration. The timing overlap may also be synchronized with a periodic ripple component in the strobe illumination, to provide improved repeatability.

A machine vision system editing environment is provided for a part program in which a continuous stream of image acquisition operations are performed during a run mode. In one embodiment, a new common syntax and representations are utilized wherein continuous image acquisition operations are recorded in the same way as regular operations, with the running of the part program being performed in two stages. In the first stage, the portion of the part program that is to have the continuous stream of image acquisition is scanned for image acquisition operations, and the most efficient order for acquiring the images is determined, after which the image acquisition process is begun. Then, in the second stage, while the image acquisition process is being performed, the portion of the part program is scanned again, with the image analysis operations then being performed.

摘要:
Methods and systems of part programming for machine vision inspection systems are provided, which permit a user to readily define multiple image acquisition operations interspersed with associated image analysis and/or inspection operations during learn mode operations and in the resulting part program image acquisition operations for at least some of the images are arranged into a continuous motion image acquisition sequence that acquires images and stores images in a “non-interspersed” manner in order to increase the throughput of the machine vision inspection system. Image analysis/inspection operations associated with the stored images are performed subsequently by recalling the store images. The programming systems and methods disclosed herein may operate automatically to facilitate rapid programming for a variety of workpieces by relatively unskilled users, wherein the resulting programs include continuous motion image acquisition sequences.
