Compare 2 images in Labview

[morgenroete1979]

Hello, Everybody.

How can I compare 2 visualization graphic in LabView ?

For example on the first image is the lamp switch off, it seems a red colour, in the second picture is the lamp switch on, it seems to be a green color.

How can I with LabView automatically compare these 2 images / this color change? Through pix compare? How can I position the right place, that this color change appears???


Thanks a lot.

Seems you are searching for functions in the vision toolkits for LabVIEW. http://www.ni.com/vision/vdm.htm

The IMAQ-Vision module is a full blown machine vision library. If you just need to compare two pictures, you may also convert them to 2D-Arrays and subtract one array from the other. The resulting array will dontain the differences of the two images.
