Aerial photograph reseau mensuration with sensing arrays
Abstract
A solid-state area array useful for taking automatic measurements of the distance separating reseau points on aerial photographs is described. The array detects the center of reseau cross images by determining points where the spatial derivative of the image vanishes. Accuracy to within a few microns on the image is reported.
