Initial Skills in the Use of Machine Vision Software VisionPro

Preface

Machine vision is a branch of artificial intelligence which is developing rapidly. Simply put, machine vision is to use machines instead of human eyes to measure and judge. Machine vision system converts the captured object into image signal through machine vision products and transmits it to a special image processing system to get the shape information of the captured object, and then converts it into digital signal according to the information of pixel distribution, brightness, color and so on. The image system extracts the features of the target through various operations, and then controls the scene according to the result of discrimination. Equipment action.

Then, from the above description of machine vision, the role of image processing analysis software is very important. At present, in the industrial field, the commonly used machine vision software are Halcon, VisionPro, LabView, EVision, HexSight, SherLock and so on. These software have their own characteristics. Today we want to introduce the VisionPro software launched by the industry giant company Cognex.

Software introduction

The VisionPro #system launched by Cognex #6 combines world-class machine vision technology with rapid and powerful application system development capabilities. VisionPro QuickStart uses drag-and-drop tools to speed up the development of application prototypes. This result can be applied in the whole cycle of application development. The application system is developed by using VisionPro machine vision tool based on C OM/ActiveX and graphical programming environment such as Visual Basic <, Visual C++<. In conjunction with the MVS-8100 series image acquisition cards, VisionPro enables manufacturers, system integrators and engineers to rapidly develop and configure powerful machine vision applications.

At present, the latest version of VisionPro has been updated to version 9.2 CR1, but these versions must use hardware encryption dog to use normally. Fortunately, Visionpro's early version 8.2 provides emergency key functionality, which can be used for learning and communicating.

Software Installation and Activation

Close the firewall, anti-virus software, decompress the software installation package, find the installation file, double-click the operation, according to the installation prompt "next step" installation can be done, the whole process in addition to the need to modify the installation location, other changes.

The VisionPro (R) QuickBuild icon will be generated on the desktop after the software installation is completed, as follows:

Double-click the icon above to open the software and go to the VisionPro (R) QuickBuild interface. Double-click CogJob1 to get to the job editor interface, as shown below. The interface prompts "The license bit for this control is not enabled. Contact for assistance ", because there is no activation license.

Next, open the Computer Start Menu and find the Cognex Software Licensing Center under the Cognex folder.

Run the software, come to the following interface, choose "Install Emergency License" and "Activate License", after the activation of the license, the software can be used normally. Here again, we remind you that the software provides five emergency licenses, each of which can be used for three days. If it is applied in the project, please purchase the genuine software.

Get the image and complete a simple application

1. Acquire the image first by following the operation.

2. Add template matching tool CogPMAlign.

3. Obtain the training image, modify the training parameters, and complete the training of the image.

4. Modify operation parameters.

5. The results of tool operation are as follows, including the number of products found, product operation score, product positioning coordinates and other information.

6. Next complete the settings of "Configuring Sended Items" and "Configuring Communications Manager":

7. Save the project file and generate the final user interface.

In this way, using machine vision to complete a simple product number statistics project is completed.

Epilogue

In addition to the software part, a completed machine vision project should include the selection of camera and lens hardware, the formulation of lighting scheme, the selection and execution mechanism of OK/NG products, etc. Here we only introduce the software part.
