Analysis and Design of Intelligent Logistics System Based on Internet of Things

Based on Internet of things, .NET software development technology and GIS technology, this paper analyzes and designs a system of intelligent distribution information with software engineering life cycle theory as the guide to solve the problem of high complexity and low efficiency of manual operation in logistics and distribution, improve the level of intelligent operation and then improve the operating efficiency. It analyzes the business requirements of the system, then designs its physical architecture, software architecture and system structure, and constructs the terminal node distribution dynamic model of transmission route, realizing the main function modules of the system and verifying the correctness and effectiveness of the system results through systematic and comprehensive tests.

Interaction with Three-Dimensional Gesture and Character Input in Virtual Reality Recognizing gestures in different directions and improving user input

Hand gesture recognition is a key aspect to make interaction of virtual reality more convenient. A good way to make users’ idea understood by computers including characters input plays an important role in interaction. Current methods of hand gesture and character input are too limited to make full use of powerful capacity that computers have nowadays. In this paper, we propose a natural 3D input method based on stereo cameras as an interface of human and machine. We segment the hand out based on skin-color detection and train a neural network based on Hu moments to recognize valid and invalid gestures defined in our paper. For valid gestures, we implement stereo matching and 3D coordinate calculation and line them up to formulate characters. Our method can robustly recognize 3D gestures in different directions and make users’ input more free compared with traditional ways
