Re: labview stereovision
Well Bill - there is more progress haha.
I got another small problem however let me quickly explain my progress.
Before I was working with a penny. I now decided that I should move onto an opaque sphere - something like an orange before pnto a football.
I set up my experiement, and from my vision script (attatched) it is all working i.e. the vision script ends by showing me the circle if it was detecteed.And thanks thanks hornless rhino - I used your advice for lighting and it has made thresholding easier. Test it with the images in the 'orange' folder. I used a constant background called 'back for orange'.
Query 1:
I manipulated my penny experiment and created an "orange VI". But I am having lots of difficulty displaying my overlay information on the output display. I think I am not understanding how to draw a 'bounding box' as thiis time I used a control as I couldn't automatically select the bounding box from the circle array. I need this to show to myself on the display where it shows the circle outline detected.
In vision script the circle lins are automatically shown - so surely there must be a simpler way than what I am doing to also easily show the circle overlay..right?
Query 2:
Now my vision script is working with a constant background. However, in the VI I want to use feedback so that I feed the background from the live camera on the second iteration of the while loop. i.e.
I want:
1) Load an initial background obtained from a file
2) I then on the next cycle want to replace this background image with the previous image which was on live camera. I know it will involve the feedback node - i included it but got stuck because I dont know how to apply this tchnique to images.I have marked it on the VI to calrify what I mean.
.....................
And well, I guess its good I still dont have my depth information (still waiting on Logitec) because Its made me go back a gear and made me learn new things I didn't kno before. THanks for your help so far
