Abstract


Multiple-Slit Streak Tube Imaging lidar (MSTIL)is a new type scanless flash lidar, it has the advantage of achieving larger field of view and higher frame rate. compare with single-slit streak tube Imaging lidar, there is more information in its every frame of image. Relying on the demonstration device of streak tube laser imaging system, we carry out the research of data processing of MSTIL, and get some fruit. for example, source of noise, the choice of algorithm of restrain of noise, streak segmentation, restrain of distance noise and so all. through imaging varied object, we prove the correctness and feasibility of the MSTIL. We also give the analysis of the error of the result of the image.In this paper, we give the scheme of data processing, compare the difference of MSTIL and the scanning laser lidar, and analyse the source of noise, and compare the infection of varied noise. Through experiment, we compare the effect of common algorithm of restrain of noise. And get a good result.Next, we research how to partition the streak from the ground, and how to extract the data of streak, we analyse some method, and improve the method of single thresh segmentation used in STIL data processing. for the reconstruction of range image, we provide two new method to restrain the distance noise.At last, relying on the method we get, we use the MSTIL provided by lab to image some object, an experiment of single object, of two objects, and an object 700m away. And also complete the data processing. Not only prove the correctness and feasibility of the MSTIL, and also prove that the method of data processing is feasible. Because of some error of the result, we also make some necessary analysis, and give the method of processing.The research results obtained provide theory and application guide for the establishment and consummation of data processing subsystem of streak tube laser imaging system, and are of far reaching importance for the development of data processing technology for streak tube laser imaging system. The key research direction of data processing technology for streak tube laser imaging system is brought forward finally based on the experimental result.
