description: Subject of the research: methods and means for determining the class of an object based on three-dimensional models. Objective: to develop a method for classifying objects, for the use of which it is necessary to collect hundreds of times less data than for training similar algorithms based on neural networks. To perform the work, the python programming language, optimization methods, triangulation and projection of three-dimensional points were used. The main results of the study: an algorithm for classifying objects in the image was developed, testing was performed on the example of the task of classifying human poses. A set of 3D models has been prepared, and an algorithm for converting them into 3D point clouds has been developed. A test dataset of images has been prepared to assess the accuracy of the developed algorithm. Experiments were carried out to test the speed and accuracy of the program. Scope of application of the results of the work: classification of poses of people, cars, various solid objects in video surveillance tasks, applications for fitness, medicine.
