| This paper describes experiments in the block adjustment of linear pushbroom sensor imagery incorporating object-space straight line constraints. Both polynomial and interpolative platform models were tested; the polynomial model generally performed better than the interpolative model without lines, but not as well as the interpolative model with straight line constraints. The greater flexibility of the interpolative model makes it better able to describe complex platform motion and to utilize the geometric strength given by the straight line constraints, at the expense of increased sensitivity to uneven point distributions or bad points. |
