Adjustment Scheme and Accuracy Analysis for Three-line Linear Array Sensed Data

This paper presents experiments and theoretic analysis of different adjustment schemes with the data acquired by the three-line parallel linear array scanner, The condition for indeterminate solutions of the adjustment system and the method of parameter selection for the optimum geometrical condition of the adjustment system have been found out. Thus, the theoretical basis has been set up for the statement that higher accuracy and stable solutions can be obtained in case that the distances of the orientation irnages are much larger than the distances of the ground points by using the data of a three-line parallel linear array scanner.
