real time image recognition

[tiho]

Hi

I try to realise real time recognition small objects. I am using Vision assistant. With color pattern matching I create a template selecting the object that I would like to recognise. Than I check if everything is OK with batch processing. Using batch processing after matching of the template with the current image the object is marked with red window. After creating labview VI application and after starting the application the red window doesn't appear. I would like to mark the matching object somehow. How I can do it with labview?

Thank You

Hi Tiho,

Can you please post the application you have developed to have a look at it? Also, please attach a sample of the picture.

Best regards,

HI

Here is my application. I would like during the work of my camera the application to look for a desired object. If the application found the desired object I want to mark it somehow.

Thank you

Hi tiho,

In LabVIEW, the IMAQ Find Pattern will return an array of cluster with all the matches of your scene.You can use the overlay functions to display either the x and y coordinates of your matches or the bounding box of each match.

Thank you for your answer. I would like to ask how to connect the camera to this code.

Thank you

Hi,

In fact, to use this code, you have to code with low level functions of LabVIEW, and forgive the express VIs that you have used, at least for the processing part.

Have a look at the examples you can find a lot of stuff there. (Help->Find examples)

Hi

I tried to correct my application but without success. I am sending the error made during the start of the application. I am using a standart web camera in RGB mode.

Error - 1074395995 occured at IMAQ ReadFile

Possible reason(s):

IMAQ Vision: File not found
