Abstract: The theory of theodolite image measurement is similar to that of general normal photography of ground stereophotogrammetric survey, but thereis no need for theodolite image measurement to take on-the-spot photos. Theodolite image measurement can be made more simple and more con-venient with no need of very expensive and special instruments. Set up atheodolite on the left and right stations separately; mount a 2m long sub-tense-bar on the tripod head which is located at the unknown point; sightthe unknown point and the two terminal points of the subtense-bar, andthen read horizontal and vertical angles after every sighting. Accordingto the observed parameters, spatial coordinates X,Y,Z of the unknown pointare able to be calculated. A good accuracy has been demonstrated by theexperiments. This method is available for the determination of the spatial coordin-ates of control points in short-range photogrammetry, the calibration of theinterior orientation of a camera and the figuration on the outline of build-ings in deformational observation.
