Trees sequence, taken in 1986 at SRI by Bob Bolles and Harlyn Baker
View in front if the International Building at SRI.

The original sequence had 128 images, taken by Flakey outside viewing orthogonal
to its linear camera path (the images were registered to remove rocking).

Images were taken 0.47244 inches apart, and are 256 horizontal by 233
vertical pixels (down from 256 by 240 in the unregistered data).

Camera focal distance = 16.0 millimeters.

In this directory are 64 fields from the original sequence, specifically
fields 32 through 95.

From Harlyn:

; focal-distance-in-millimeters	(for sony 16mm camera lens)	
; updated on March 11, 1986 from Bob's notes
16.0 mm
0.62992 inches

; u-pixel-in-millimeters (camera image plane pixel sizes in mm)
0.03271266 mm
0.0012879 inches

; v-pixel-in-millimeters
0.02562606 mm
0.0010089 inches

; image center
; These 2 form the horizontal aim vector of the camera, 
; for relating (u,v,t) to (x,y,z).
; Looking ahead and slightly down
(128,128)

Note from Harlyn: The image centers seem too good (half the image
dimension) to be true.  I'm not sure we ever measured this (I'll check
the other hardcopy notes).
