In engineering geodesy a great variety of measurement tasks require contactless, high- accuracy, true-to-geometry measurements of nontargeted object features. For this reason a system using image processing is under development for automatic coordinate measurement. During the conceptual development phase of the instrument, it is very important to test the future hardware and software components of the system to achieve the best solution. This paper describes the investigation of the pointing accuracy of a computer-controlled motorized theodolite using an integrated CCD camera in its telescope. A program was developed to test the pointing accuracy within reach by means of a CCD camera and image processing software. Targets of different sizes and shapes were used at different distances for testing.
