ABSTRACT:
In a photogrammetric analytical measurement system, a survey map is produced on the basis of two respective photographed pictures obtained at two different photographing positions. Each of the pictures includes an object image to be recorded on the survey map, and a standard measurement scale image for producing an accurately scaled object image. Data for producing the survey map is approximately calculated on the basis of two-dimensional position data inputted to the computer by designating the scale image and the object image on the pictures with a cursor, by an operator's manipulation of a mouse. When the results of the approximate calculations are erroneous, it is indicated that the inputting of the two-dimensional position data, by designation of the object image with the cursor, should be repeated.
