Grey dots?

[Eduardo1972]

Hi everybody, yesterday i did my first capture and it went really good, but there were some grey dots in the head and hands, the dots makes the head and hands jump to extreme rotations, somebody any advide will be welcome.

Thanks a lot

Sounds like the markers are being seen in 2 different places, by different cameras.

I would try resetting the calibration, running it again at 150 data points and medium speed, and see if that rectifies the issue.

How do you have your system setup, setup area size?

Number of cameras?

PC being used?

Hi Vincent, i have 12 cameras and the room is not square is more like a triangle, so the cameras have diferent distances in relation to the center of the capture area, one thing that we just realize is that we were doing the calibration wrong, because we just stand with the wand and we didnt lay on the floor so we were occluding the wand to several cameras, the room is 5 meters x 5 meters more or less, maybe we must buy the wide lenses for the cameras, the way we put the cameras is as follows: we use 12 tripos the even cameras we put the tripod all the way high(tall tripod) and aiming at the chest of the actor so the chest is exactly in the middle of the screen, and the lower cameras are like 1.6 meters high and aiming at the feet so the feet is exactly at the center of the screen. The cameras that are lower see the feet and up to alittle lower of the waist, the high cameras no one sees the feet and goes up like 0.5 meters above the head.

Thanks a lot

OK, I would start off by adjusting the center points of the cameras. You should place a single marker, waist high, and aim all of the cameras at that point. As the cameras work best, when they have the largest overlap viewing area.

You can also try rotating the cameras 90 degrees, to try and get the optimal capture volume, for this small of an area.

Thanks Vincent!!

If i point all the cameras to a point(waist high) in several cameras i cant see the arms if they reach up high and some of then dont see the head, maybe the room is too small? if this is the case can you recomend me a lens for the cameras?
Could you explain the 90 degrees rotation, in which direction? maybe pointing 90 degrees downwards because of the small area?

Thanks a lot

Eduardo:

What he means is that you set the cameras on their side... These cameras have a wide field of view horizontally when oriented normally... if you set them on their side... then the wide field of view becomes vertical.
