ARCHIVES OF | PHOTOGRAMMETRY, Vol. XlE4, 1956 Appendix to the INT Communication to VIII International Congress for Photogrammetry Reprint from Svensk Lantmäteritidskrift Congress Number 1956 Commission TI NUMERICAL ADJUSTMENT OF X-INCLINATION AND LATITUDE DISTORTION IN STEREOSCOPIC PLOTTERS L. E. Lycken In [1], B. Hallert has developed the grid method for the determina- tion of systematic deformations of the pencils of rays in stereoscopic plotters. This method, which in [1] has been applied to the determina- tion of translations, rotations and radial distortion, may of course be extended to all kinds of systematic errors. In the Wild stereoplotters A 5 and A 7, x-inclination and latitude distortion (x-Schiefe and Breitenfehler) are of a systematic character. It would hardly be possible to adjust the instruments perfectly, so there will always remain a certain amount of errors, caused by those imper- fections. In this paper a method for numerical determination of the sources of such errors shall be demonstrated. The quantities of errors determined may serve as a check of the adjustment situation of the in- strument, or they may be used for numerical computation of correc- tions to the measured coordinates and parallaxes. Latitude distortion and x-inclination appear because the collima- tion line of the measuring system fails to coincide with the normal to the diapositive plane from the centre of the lens carriage cardan. A displacement in the longitudinal direction of the swinging girder will result in latitude distortion, a lateral displacement in x-inclination. In the following deductions dl denotes a longitudinal and dt a lateral displacement of the measuring mark (M), projected through the ob- jective into the diapositive, in relation to the orthogonal projection (P) of the centre of the upper cardan on the diapositive plane. The deduc- tions will be made in the projection plane, i. e. the axis of the swinging girder will be considered as placed in front of the projected image area. The following relations may easily be derived from the figure by means of a simple coordinate transformation: iii
