Abstract

In this publication we investigate the image coding method for 3D range-gated imaging. This method is based on multiple exposure of range-gated images to enable a coding of ranges in a limited number of images. For instance, it is possible to enlarge the depth mapping range by a factor of 12 by the utilization of 3 images and specific 12T image coding sequences. Further, in this paper we present a node-model to determine the coding sequences and to dramatically reduce the time of calculation of the number of possible sequences. Finally, we demonstrate and discuss the application of 12T sequences with different clock periods T = 200 ns to 400 ns.
