An algorithm for the realization of three-dimensional laser imaging system's intensity image and range image based on multiple-slit streak tube

摘要

The technology of three-dimensional laser imaging is applied widely in the field of military use and civilian use etc. There are mainly two methods for three-dimensional laser imaging. One of them is based on APD arrays, and the other is based on streak tube. The latter represents relatively mature technology for providing high-resolution 3D laser radar images. In both of them, the realization of intensity image and range image is the foundation and key of three-dimensional laser imaging. It presents the method for three-dimensional laser imaging using multiple-slit streak tube to get clear, exact intensity image and range image. The multiple-slit streak tube imaging lidar (MS-STIL) approach uses several slits instead of the usual single slit to provide a number of additional capabilities over conventional laser radar systems. And it researches into the algorithm for the realization of intensity image and range image and processes the simulative streak tube image with it via the analysis of multiple-slit streak tube's imaging theory, and finally carries through the simulation of intensity image and range image.
