Problems alignin in 3D, plese help!!

[richon]

Hi, im a new user of agisoft and also new in photogrammetry,i have a few problems to align the images. I take pictures of objects in 360º with 166 pictures or less(not less than 70). I take the pictures in a small white studio with enough light, f8 aperture and in 35mm(50mm with the1.4 multiplier factor of my canon 7D) and 18mpx in RAW, but the images appears only in two or three places one over another not in 360º degrees.
I attach 3 pictures to this post two of the problem and another one of a picture that aligned correctly to demostrate how i take the pictures.
Could anyone help me to solve the problem? i don´t know what i do wrong.

1st i take the picture
2nd  add pictures
3rd align pictures
4rd everything goes wrong

Thanks
