Human-robot collaboration is a key concept in modern intelligent manufacturing. Traditional human-robot interfaces are quite difficult to control and require additional operator training. The development of an intuitive and native user interface is important for the unobstructed interaction of human and robot in production. The control system of collaborative robotics described in the work is focused on increasing productivity, ensuring safety and ergonomics, minimize the cognitive workload of the operator in the process of human-robot interaction using contactless recognition of human actions. The system uses elements of technical vision to get of input data from the user in the form of gesture commands. As a set of commands for control collaborative robotic complexes and training the method proposed in the work, we use the actions from the UTD-MHAD database. The gesture recognition method is based on deep learning technology. An artificial neural network extracts the skeleton joints of the human and describes their position relative to each other and the center of gravity of the whole skeleton. The received descriptors feed to the input of the classifier, where the assignment to a specific class occur. This approach allows reducing the error from the redundancy of the data feed at the input of the neural network.

This paper proposes a method for reconstructing a depth map obtained using a stereo pair image. The proposed approach is based on a geometric model for the synthesis of patches. The entire image is preliminarily divided into blocks of different size, where large blocks are used to restore homogeneous areas, and small blocks are used to restore details of the image structure. Lost pixels are recovered by copying the pixel values from the source based on the similarity criterion. We used a trained neural network to select the “best like” patch. Experimental results show that the proposed method gives better results than other modern methods, both in subjective and objective measurements for reconstructing a depth map.
