Fundamental to the video measurements is the transformation between two- 
dimensional video images and three dimensional world coordinates, which 
requires a determination of camera geometry. This was accomplished with 
visually identifiable ground control points (GCP’s) in the cameras’ field of 
view. The 38 GCP’s established during the experiment consisted primarily of 
white square signs or highway safety cones painted black and placed on the 
beach. Coordinates of the GCP’s are listed in Table B2 and shown graphically 
in Figures B3 and B4. Many of those GCP’s were temporary, with a select 
number positioned on any particular day. A few instrument pipes and the north 
property fence posts served as permanent GCP’s throughout the experiment. 
All video data, with the exception of time exposures, were collected on 12 
Super-VHS video cassette recorders. Each VHS tape recorded two continuous 
hours, with 4 or 5 runs (8 to 10 hours) collected each day. The collection 
schedule is listed in Table B3. Several duplicate tapes were made between 16 
and 19 October, with times staggered approximately 15 minutes, to ensure 
data redundancy and to obtain data in the time gaps between video runs. Data 
runs are sequentially numbered and include the camera designation. For 
example, run R101 refers to the first run of camera R1. Video tapes for each 
run had near-synchronous start times and a common SMPTE (Society of Motion 
Picture and Television Engineers) time code recorded on one of the audio 
tracks. All DELILAH tapes are in the possession of Dr. Robert Holman, who 
can be contacted regarding obtaining copies (see Appendix G).
