Abstract: A polar navigation window period assessment system based on three-dimensional visualization simulation of ship-ice interaction is provided in the present application, including a virtual reality interactive operation module for interacting with virtual reality scenes based on a virtual reality (VR) handle and a VR helmet; a three-dimensional virtual visualization integration module for observing the virtual reality scenes from a global perspective; a three-dimensional simulation module of the Arctic route environment for simulating a route environment scene; an Arctic navigation virtual scene module for establishing a navigation virtual scene; an Arctic navigation window period assessment module for assessing navigation window periods of the ship on different routes; a system storing and outputting module for storing interactive operation information, virtual reality scene information and window period assessment result information, and outputting them in form of curve diagrams and data tables.

Abstract: The present invention discloses an apparatus and method capable of automatically identifying an obstacle in front of a mobile terminal, the apparatus comprising a transmitting module, a receiving module, and a controller MCU module. The transmitting module is in signal connection to the receiving module, the transmitting module and the receiving module are both in signal connection to the controller MCU module (STM32 series), and the controller MCU module is also in signal connection to a mobile terminal CPU. The present invention may automatically identify the road condition in front of the mobile terminal and may carry out a voice prompt in time.
