Photogrammetric Potentials of Non-Metric Cameras.

摘要

An analytical data reduction approach particularly suitable for non-metric photography has been developed and tested using fictitious as well as real data. The accuracy of photogrammetric system has been investigated and an expression for estimation of the accuracy of the total system has been developed. Experimental investigations using a number of metric and non-metric cameras indicated that photogrammetric systems incorporating non-metric cameras are capable of achieving accuracy levels acceptable in numerous areas of application of close-range photogrammetry. Accordingly,it is recommended that non-metric cameras be seriously considered for data acquisition in those areas of close-range photogrammetry,where the accuracy requirements permit. (Author)
