4 point calibration

Hello,

I just do not get on! How can I implement a 4 point calibration? There are these great wizard in the yes it is, I only need this option in my program, I have always equalize different images, which are taken from the side, I know the mass of the object and then the four points with values of size may specify.

LabVIEW always want to create a template, only that I can not use because my object is always changing.

Although I have found in the file hilfts something but do not know how I should verstehel the formula or can implement in LabView.

Hi,

 

you need to create a calibration template once. You can use the wizard for template creation. For use in your program, there are VIs that read in the template and apply the calibration algorithm to the images that are captured

Have a look at these examples to lear how to use calibration within your VI:
