| Abstract: | This paper presents a simple least squares approach to determination of exterior orientation parameters using a parametric form solution to the conventional collinearity-condition equation for a single oblique photograph. A MATLAB based program has been written to perform the required computation by two methods namely; “iterative model” and “noniterative tilt photo-geerator equation”. With a Standard error of 10.77m, 10.77m and 279.31m for the𝑋0, 𝑌0 and 𝑍0 respectively, the “Non-iterative Tilt Photo Generator Equation” Model was chosen as a better fit for the Solution although the accuracy achieved is unacceptable for higher order survey tasks. This therefore confirms that stereo images are better suited for higher order survey task |
