THE PHOTOGRAMMETRIC CLOUD MEASUREMENT PROGRAM
Abstract
This program is conducted to determine the coordinates of a point in space using coordinates taken from a photograph and measured camera calibrations. The program consists of two parts; (1) The data adjustment program (DAP); which linearly adjusts data taken from the photographs, and (2) The general intersection program(GIP); which takes the output of DAP and with measured camera calibrations determines the coordinates in space in a normalized system of axes. No practical range restrictions are made. The input data are treated as integers. Therefore, the output has the same scaling and significant figures as the input. DAP uses standard linear adjustment methods. GIP uses rotation and translation matrices based on photogrammetric work. DAP of the program uses approximately 700 locations; GIP uses approximately 1400 locations. DAP will run about 90 points per minute. GIP requires 4 seconds for computing the necessary matrices and operates on the data at the rate of about 50 points per minute. (Author)
