Show a contact point in an specimen image

[denis crottet]

Good morning,

I acquire data which are related to the position of a contact force on a
specimen. To display the result, I would like to import an image of the
specimen and visually indicate the position of the contact force according to
the measurement.
In other words, I would be able to draw 2 axis which defines the contact point
and wich depends on the measurements in a 2D image of the specimen.

I was unable to find out a predefined function or vi which could do
this. Moreover, as my knowledge in Labview is quite restricted, I really don't
see how I could implement this.

Any idea ?

Thanks in advance for the help.

Hi,

First thing you have to do, it post one of the aqcuired images (or two)!
Don't send jpg, but use bmp, gif, png, or set the tolerance of the jpg to 0.

Without images, it will be very hard to help.

Regards,

Wiebe.

You probably want to look at using the Picture Control VIs. These allow
you to draw an image such as a jpeg or bmp. You can then draw lines,
circles, etc using the other picture VIs. The picture examples will
show how to use the various blocks.
