Meyer-Photo0068.jpg Photogrammetry
« on: February 08, 2011, 21:41:02 pm »
I posted some Photo0068.jpg with overlay

Base photo0068.jpg graciously posted by Dynodon
 
IMAGE 1

File OT z-axis, raw file, angle of view ellipse correction not applied
 
Slot Dimension for matrix run x:123 z:575

IMAGE 2
 
View of OT8 and OT9 showing different cell thickness
OT8 shows IT8 below the top edge of OT8
OT9 shows IT9 above the top edge of OT9

IITR p 28 0.035 0.049
QRA Quick Ratio Matrix: angle of view ellipse correction not applied but y axis corrected somewhat by keeping angle of
measurement the same.
 
Quick Ratio 31:23  =1.347  0.035 x 1.347 = 0.47
          if     32:23  =1.391  0.035 x 1.391 = 0/486 (0.49)

This is just to check if the IITR values of p 28 are reflected in the Demonstration Unit that was built.
