INTRODUCTION
This computer program generates a punched paper tape
which drives the servos on the electro-optical rectifier. The rectifier
processes oblique frame, strip and vertical panoramic photography.
It works on the principle that all lines perpendicular to the principal
line have a constant scale (neglecting the effect of terrain relief).
The swing angle is set prior to rectification, so that the principal
line is perpendicular to the scanning slit. See Figure 1. As the copy
is moved past the slit, the scanned information is projected to a
recording cylinder by a high resolution imaging lens. The rate at which
the copy is scanned is controlled by the paper tape to correlate with
the constant rate at which the recording cylinder is rotating.
The computer program calculates the position and velocity
data required by the rectifier servos for each scan. The following
basic terms are required:
V, the position (rectangular coordinate in
inches) on the recording cylinder.
V, the constant velocity of the recording cylinder.
v, the position (rectangular coordinate in inches)
of the "line" to be projected.
v, the velocity of the copy platen carriage in the
direction perpendicular to the slit.

The procedure for rectification requires that the initial

The other initial positions (Vol Bo, Lo, To) are computed and printed
for use in the initial coarse adjustment of the rectifier carriages.
The computer then proceeds to "scan" the copy and punch the paper
tape which will drive the servos to the computed positions.

where,
vo (inches); the initial (maximum) position
of the copy platen.
of (inches); the final position of the copy platen.
t (degrees); the resultant tilt of the photograph.
S the scale change from the original
photo to the rectified photo.

The tilt of the photo, t, is not required by the panoramic program;
the radius of the earth, R, is not required when the corrections for
earth curvature are not needed, i. e. , if h < 50, 000ft (8. 2+ N. M. );
the photo size is not required if the initial and final magnifications
clearly indicate which rectifying lens will be used. All other quantities

Oblique Frame Photography
The computations for each type of photography may he
divided into two sections; the first part is computed only once for each
photograph, the second part is an iterative loop computed many times
for each photo. The procedure for oblique frame photography involves
the following computations.
A. Preliminary Calculations
1. Breakpoint 0 must be set for oblique frame
photography.
2. The input is read and the tilt is checked. If
t < 3 ?, no rectification is required; if t > 60?,
rectification is not possible.

6. The proper rectifier lens is determined in the same
manner as for oblique frame photography (eq. 6, 7,

7. The height of the photograph is compared with
hr (as in oblique frame photography) to determine
whether or not the corrections for earth curvature
are required.
8. The initial position of the copy platen, vo, is given
as input. The corresponding initial position
of the recording cylinder, Vo, must be computed.
a. For h hr, the corrections for earth curvature are
required. The appropriate switches are set depending
on the value of h.
(4) Using the input value of vo, the position of the copy
platen, the value of Vol the initial position of the

The program is now ready to start the iterative loop, which
will be continued unti`i the entire photograph has been processed, or until
3600 scans have been completed.
(5.) Given Vk, the position on the recording cylinder
for this scan, the program computes vk, the
corresponding position on the copy platen for this
scan. The formulae used vary with the type of
photography and the height of the photograph. The
velocity of the copy platen carriage perpendicular
to the slit, vk, is also computed.
(6.) vk is compared with vf, the input value for the
final position of the copy platen. If vk < vf, the
photograph has/been completely processed in less
than 3600 scans. Control is transferred to (13).
(7. If vk ' v f, the remaining quantities for this scan
are computed:. Bk, Bk, the position and velocity
of the lens carriage; Lk, Lk, the position and
velocity of the copy carriage; and Tk, the position
of the variable density filter for exposure control.
The changes in the velocities, L1vk, GBk, and OLk,
are then computed.

are processed into the format required on the paper
tape for the rectifier. The message for this scan is
written to magnetic tape.
(9.) The value of Vk4.l, the position of the recording
cylinder for the next scan, is computed.
(10.) When 3600 cans have been processed, control is
transferred to (13). Until this time, control
returns to (5) to compute vk for the next scan.
(13.) In most cases, the entire photograph has been
processed. In some cases, however, 3600 scans
have been computed, but the photograph is not
completed. In either case, the message for
each scan has been written to magnetic tape.
Now the entire set of messages is punched on
paper tape, the paper tape is checked for parity
errors, and, if the tape is satisfactory, the
output (photo identification and scan messages) is
copied to the rectifier library tape for permanent
storage.

14.8 Format of the Punched Paper Tape
The three carriage positions, (v, B, L), the three
changes in velocity (Av, AB, AL), and the position of the variable density
filter, (T), are calculated for each scan of the photograph. These seven
quantities are in floating point format when they are calculated and they
must be transformed into binary integers and punched on a paper tape
which will be interpreted by the digital decoder of the rectifier.
A. The carriage positions (v, B, L) are transformed into
12 binary bits. This is equivalent to an accuracy of . 0002
inches. This is exactly 2 rows on the punched tape and
can be expressed as 4 octal digits. Therefore the positions
must be transformed into octal integers between 0 and 7777.
The carriages are coarsely positioned, prior to rectification,
using the initial positions which are calculated in the program
and written to the Monitor Printer. The punched paper tape
thus requires only the fractional part of the positions in each
scan message. Thus if we say that each quantity (v, B, or I-)
is composed of an integer part (which may be zero), and a
fractional part, we have
V = V-1 + of
(56)

-RDP9I*Q 7WOMQQ04AQQ3T,
15 March 1962
Thus we may say that on the punched paper tape,
v = of
(57)
The program drops the integer portions of the 3
positions and retains only the fractional portions which
are still in floating point format. The positions B and L
must always be positive, but v can be either positive or
negative. After dropping the integer portions we have,
IvI, B, LC1.0 (58)
The three fractional positions are now changed to fixed
point and multiplied by 4095. The results are rounded
to the nearest integers, so that
0 - IvI , B, L < 409510
(59)
These decimal integers are converted into octal, so that
0 c I v I , B, L 7777q
(60)
The 4 octal digits for each position are punched on the paper
tape as 2 rows of 6 binary bits each.
If v is a negative number, its value is complemented before
being punched. This is the 10's complement if equation 58
is considered, the 8's complement if equation 60 is
considered, or the 2's complement if the 12 bit binary integer
is considered.

B. The change in velocity data (Av, LAB, AL) are not required
to as much accuracy as the position data, and are given
only 6 binary bits each. This is exactly 1 row on the
punched tape and can be expressed as 2 octal integers.
Therefore, the delta velocities must be transformed into
octal integers between 0 and 77.
Before the delta velocities are transformed into octal
numbers, "velocity constants" are introduced. In other
words, Av, AB, and LPL are multiplied by a factor, K,
the purpose of which it to increase the range of these
velocity changes, so that the expression,
0 1A-0 , I'Bl , (AL I c 1. 0 (61)
is a realistic equation.
Forcing the quantities to span the entire range from zero to
one increases the accuracy of the final binary result which
has an accuracy of .016 inches/sec. The K value now
K
being used for LSv, LAB, and AL is 50, (the 3 velocity changes
are basically less than . 02). It is likely that experience in
the rectification of actual photographs will indicate a change
in this constant for one or more of the velocity changes.
These modified velocity changes may be either positive or
negative and are still in floating point format. They are now
changed to fixed point and multiplied by 63. The results

The 2 octal digits for the magnitude of each of the changes
in velocity are punched on the paper tape as 1 row of 6

The signs for these quantities are translated into 3 binary
bits (1 indicates -, 0 indicates +) which are also punched on
the paper tape.
C. The position of the variable density filter (T), which controls
the exposure is given in 7 binary bits. This is equivalent to
an accuracy of . 008 of a revolution of the filter. This is 1
row plus 1 bit (on the next row) on the punched paper tape
and can be expressed as 3 octal digits (the first of which is
a 0 or a 1). The value of T is transformed into an octal integer
between 0 and 177.
Since T represents a fractional part of 1 revolution (360?)
it holds that

This decimal integer is changed to an octal integer,

T can now be expressed as a 7 bit binary number.
The first 6 bits are punched on one line and the last
bit is punched on the next line, followed by 2 positions
which are not used, and then the 3 sign bits for the
delta velocities. It must be stressed here that this
binary integer must not be treated as the other 6
quantities in regard to the transformations from octal
to binary and vice versa. When the length of a binary
number is divisible by 3 (as in 12 bits for v, 6 bits for Av),
it is possible to translate binary to octal starting with the
3 left-most digits. The proper way, however, for any
length binary integer, is to start the right and work
backwards. Thus the array,

to punch this number in the required format, the

It has been determined that a special initial message should

A. Punched Paper 'Kape
This is the primary output of the program. The tape contains up to
3600 scan messages in the.format described in section 14.8. The last message
is followed by an ED. The computer program includes a procedure for
checking parity on this tape.
B. Monitor Printer
The photo identification and the photo input are written to the Monitor
Printer after they are read. The initial rectifier settings (vo, Vo, Boo Los
To) are written after they have been computed. The proper rectifying lens is
also written to the Monitor Printer, as are operator instructions and messages
accompanying any programmed error stop.
C. Magnetic Tape
As each scan message is formed, it is written to a magnetic tape,
on which the photo identification has also been written. After the last scan
message, and ED is written. This magnetic tape is used to punch the paper
tape, and then the contents of the tape are copied to the end of the rectifier
library tape for reference if the paper, tape for this photo should ever need
to be repunched.
D. High Speed Printer Output
If breakpoint 1 is set, a hard copy output is obtained on the High
Speed Printer. There are 6 lines of printing for each scan message.

14. 10 Operating Instructions
The first part of the operating instructions would be common to any
program but is repeated here so that the operator can develop the proper
housekeeping techniques.
1. Mount a work tape, with a ring, on tape station 10. Mount a
copy of the permanent library store tape, with a ring, on tape
station 20. If for any reason tape station 10 is not in operating
order, the console operator should read memory at 00 12 10 and
place the number of a working tape station in the last two digits.
If tape station 20 was not in operation order the operator would
read memory at 00 12 20 and place the number of a working
tape station in the last two digits.
2. A TLT library tape should be mounted on any other available
working tape station (with no ring).
3. The operator should type up the following paper tape message.

4. Clear the computer memory.
5. The operator should now block read forward into 130000 from
the TLT library tape station, set the "P" register to 13 00 00,
set an "X1" status level and depress and release the start
button. The above operation will bring in the rectifier program
from the TLT library to the computer memory.

points for the rectification of the photograph, the computer would automatically

"Set Break Points as follows - Frame BPO, Strip BP2, Panoramic BP4"
The operator would then set one break point and continue.
2. If the operator resets one of the above break points during the operation
of the program the computer would go to a program error stop (PES).
The operator would then have to restart the rectifier program from
the beginning in order to continue.
3. The computer compares the input tilt value to 3 degrees. If the
input value is below 3 degrees the monitor printer will print the following:
"No rectification required on the photo".
The computer would then go to PES and the program would be completed.

"Tilt too large photo cannot be rectified. "
The computer would then go to PES. The tilt value on the input tape
would then have to be changed and the program restarted from the

would be to determine if M1 is less than 1. 3, and M2 is greater than 4.
If this condition is present the monitor printer will print the following.
1'M1, M2 error condition. "
The computer would then go to a PES. In order to continue the program,
the values of M1 and M2 must be changed so that this error condition no
longer exists. A new input paper tape must be produced and the program
started from the beginning.
9. The computer will now generate the control tape for the rectifier.
The program is so arranged that if any delta velocity exceeds the
maximum velocity of the servo the monitor printer will print:
"xxx Over limits". '
where the x's represent the number of the scan that exceeded the maximum
servo velocity.
10. As stated in step 5 of this section, the rectifier program could have
gone down one of three paths. The error print outs were the same for the
frame and strip as shown above. For the panoramic program the tilt
value is calculated instead of being given as in the frame and strip program.

The value v0 is calculated and compared to 60 degrees. If this
value exceeds 60 degrees the following print out occurs.
"v zero f too large for rectification".
The computer would then go to a PES. In order to continue, the
starting point vo must be changed so that when divided by f its
result should be smaller than 1. 0472 radians (60 degrees). The operator
would then produce a new input tape and restart at the beginning.
11. The panoraXnic program would have the same error restart
procedures as the frame and strip for the following print outs:
"Ml scale too small. Determine new S" on the panoramic program
would be identical to "Ml is less than 0. 5. Determine a new factor S"
as shown in step 5 of this section for the frame and strip program.
12. The error print out of:
?M2 scale too large. Determine new S"
for the panoramic program would use the same restart procedure as:
'fM2 is greater than 9. Determine a new scale factor S".
in step 7 of this section for the frame and strip program.

14. 13 Timing
The rectifier program running time will depend on the input
parameters. The longest possible program will be one in which the taking
camera is located above 50, 000 feet and a combination of its other parameters
such that it would require more than 3600 scans to complete the scanning
of the negative. For the above case it would require approximately 4-1 /2 hours
to complete the program and punch out the control tape. In the 5 months we
have produced rectifier tapes, for the testing of the rectifier, we have found
that the shortest program was about 1/2 hour. The average time we have
estimated would be about 1-1/2 hours per program.
