Abstract:

The article is devoted to the actual problem of recognition of 3D objects by a laser location system based on the detection of patterns hidden in the time profile of reflected signals.

Target. Substantiation of the stages of a systematic approach to the automated design of blocks for intelligent analysis of signals of optoelectronic location systems for the synthesis and analysis of algorithms for classifying 3D objects.

Based on the morphological analysis of the impulse reflection characteristics, an expert model of six initial features characterizing the dimensions, energy properties, and shape of 3D objects is proposed. The main component method is used to map informative features into a two-dimensional space. The cluster data structure in the space of the main features is investigated. Machine learning methods have been used to obtain optimal robust estimates for the parameters of alternative algorithms for classifying 3D objects. The cross-validation method confirmed the presence of the generalization property of the discriminant functions of classifiers.

Based on the morphological analysis of reflected signals, the efficiency of solving the problem of recognizing objects with a complex electrophysical structure and shape by means of a single-position short-pulse laser location system by the price-quality criterion is demonstrated.
