Helooooo ..

I would like to receive an image (JPEG-pdf) of course showing the exact position for three cameras.
With the distances and heights between each cameras (ankle ?)
.Basic calculation would be of 4m between the central camera and the actor

in mp or another.
thanks a lot

Hi Pat !

i seen it but there is not the distance between the camera.
i ask this because after any more test my tracking is not correct.
i don't understand why

i make a test with:
one camera central with a distance of 4 m between the cam and actor (height 2 m)
second camera to left (heigh 1.0m) distance between central and these 3,5 m distance with actor 4m
third camera heigh (1.5m) distance between central and these :3,5 m distance with actor 4 .m

i created aprroximative semi circle as this : the actor is not in the center.

____________________actor
____________cam left_________cam right
___________________central

It sounds as if your distance is fine. If the performer is not in the center and you would want him or her there, you just have to rearrange your virtual cameras inside IPI-Soft. Walk up to each camera and, with your fingers, signal to each camera 1,2 or 3. When you view your video later, you can arrange the virtual cameras to match your physical camera placement. As long as you can see the entire body in the frame you should have no issues with your tracking.

What problems are you having specifically?

Pat

Thanks Pat,

The problem is:

after empty backgroung, i take a t-pose, with the hands turned face camera.
the body is entire in the frame left, right, center.

action ...

and the tracking loss the arms ...
the arms and hands doesn't recognized ...
and the feets are in full artefacts.

i meaming at a incorrect background.
the clothes are contrast.
the lights come from the large windows. day light
when we look at the video file , the gray(grey) are not contrast.
the wall is white


but the trial version expired very soon. and i didn't nothing !!!
i bought tripod, three cam. i' m waiting an answer from the team.

but your comments are very very apprecied !


ps: i have any jpeg files and video files (calibration and take) in h264 ...
regards

Are you using a laptop or a desktop computer? As long as you have a camera in front of you, and one on the left and right of you, you should be fine. If you are checking "Track Shoulders" try not checking it. Sometimes that helps. Also, what color are the clothes you are wearing? I find that black. blue green and red work great for creating contrast. Is there any shadow on the wall? If so, the software could possibly get confused.

Keep us updated :)

it's a workstation. fine for 3d and another.
about clothes, the jean is blue the shirt is orange, shoes are black.
no shadows on backgound and wall.
i tried without and with (enable shoulder tracking".
thanks

Make sure that if you are wearing a long sleeve shirt that both sleeves are down and buttoned. Otherwise the software will get confused because of the color difference.
Keep us updated :)
