object tracking

[jfalk7]

Hi,

I am currently doing a research project on object tracking using the NI vision software with labVIEW and I have seen many examples that would be good for the purposes that I am trying to use it for but no matter what file I find in this forum there are always functionals that I cannot run because I do not have them in my version of IMAQ. I dont know how I can correct this. Any thoughts?

Thanks for the help,

Jordan

Do you have the Vision Development Module installed? I believe that's what must be giving you issues?

[jfalk7]

I am pretty sure I do I am using a computer that has been used in the past for other research projects that use the vision software. Could it be that the vision software is too old?

Hi,

Is the vision development module the same thing as IMAQ? Because that is what I am currently using and I am missing commands like cast image or like match pattern, etc. I am attaching a copy of the VI so that you can see what I am talking about.

Thanks again for the help,

Jordan

Hi jfalk,

IMAQ and VDM are indeed different. IMAQ deals with acquiring an image while VDM has most of the actual image processing and machine vision functions.

Here is a KB which explains the differences in more detail.

NI Vision Module is designed to help develop and deploy machine vision applications . Includes hundreds of functions to acquire, process images , location of features, identify objects and measure parts.  The Vision Development Module ( VDM ) presents image processing functions for LabVIEW , C / C , Visual Basic, and . NET . VDM functions are used for image processing some of them are : pattern matching, particle analysis , edge detection , threshold , histograms and optical character recognition . Furthermore, VDM includes Vision Assistant and code generation tool similar to VBAI . Vision Assistant is a useful tool to develop and test a series of image processing steps and code generation .

 
Vision Builder for Automated Inspection ( VBAI ) is a standalone development environment that requires no programming . VBAI includes over 100 of the most used VDM tools , including : pattern matching , OCR , and particle analysis . VBAI can run programs on remote destinations , and also has the ability to configure the remote targets .
 
Vision Acquisition Software ( VAS ) is a set of drivers and utilities functions to acquire, display and save images from any camera NI GigE Vision camera , or IEEE 1394 (Firewire ) and USB . VAS is included in both VDM and VBAI .
 
You can perform image acquisition only drivers from VAS , but for any treatment or handling or VDM VBAI you need , plus VAS . You can download the evaluation software from the following links :

In this example, we will create a program in Labview to capture images from a USB camera to your application for further processing using the NI Vision module.

In the next block of functions perform continuous capture of images and show it in the indicator function RGB images using Vision Express (parameters to control zoom, focus, contrast, etc.), then extract the image plane Original leaving a grayscale image (8 bits)

[CarlosOtiniano]

In the following function block proceed to perform the extraction of the pattern with a function for image processing that captures the last event of the RGB (extract image and coordinates)
