Abstract:
A methodology and algorithms for obtaining long range 3D portraits of objects by 2D distributions of intensity of truncated realizations of reflected laser radiation are considered. The methodological and instrumental aspects of increasing the resolution of 3D portraits in terms of topography depth are investigated. Relationships between the relief resolution and optical contrast of the object surface are obtained. It is shown that the resolution can be less than 1 cm. Using the same probing pulse power, the proposed methodology and algorithms allow a tenfold increase in the range of 3D lidars compared to ToF (Time-of-Flight) technology based on the "Range-gated imagers" algorithms. The proposed scheme also provides the possibility of implementing this methodology using standard components without the need to use specialized integrated ToF processors.

Keywords:
3D-portraits, 3D-images, laser-location recognition.
