Paper Abstract

In the present publication we introduce coding sequences with quasi-ambiguous combinations for 3D imaging. With this extended imaging method it is possible to apply 15 combinations of gray level for the coding of range- gates in 3 images. Nevertheless, it is demonstrated that a maximum number of only 13 combinations can be connected to sequences. In this publication, the impact of quasi-ambiguous sequences on the 3D depth mapping capabilities is studied and discussed. An analysis of simulated image sequences was performed with different portion of noise. At low noise levels it is shown that the quasi-ambiguous coding sequences can enlarge the depth mapping range. But misinterpretation of data reduces dramatically the range accuracy at high noise levels. Therefore, 3D imaging profits from the application of quasi-ambiguous sequences only at low noise level.
