Problems solved by technology

First of all, the high-definition camera used in the above invention can only be used for shooting, and cannot perform obstacle detection or scene modeling; secondly, the GPS positioning device used in the above invention can only be used in open terrain, but cannot achieve accurate positioning in buildings
Finally, the above invention has no means to guide the rescuers to the rescue site
Due to the complex structure of the building, if there is no precise positioning and intuitive navigation, the rescue time will be delayed, resulting in casualties

Embodiment

[0116] A specific embodiment of the present invention is described below. In this embodiment, the helmet uses Microsoft's HoloLens as a hardware platform, and runs the method of the present invention under its built-in Windows 10 system. In this embodiment, the FIT Building of Tsinghua University is selected as a test building, a three-dimensional map is drawn, and usage scenarios are simulated.

[0117] In the present invention, the user uses voice and gestures as instructions to interact with the helmet. Gesture commands include "tap down" and "drag", meaning "OK" and "move model" respectively. Voice commands are mainly divided into gesture mode commands, 3D model commands, visual enhancement commands, environment recognition commands and navigation commands. The specific voice command functions are shown in the table below:

Abstract

The invention provides an intelligent helmet for rescue in a building and a rescue navigation method using the intelligent helmet, and belongs to the field of fire evacuation. The intelligent helmet comprises a helmet body, a CPU, a storage unit, a gravity sensor, a gyroscope, a horizontal acceleration sensor, a geomagnetic meter sensor, a common camera, a depth camera, a microphone, a voice player, a battery and a holographic lens. During use, a three-dimensional model of the building is established in the preparation stage, key points are calibrated in the model, and communication information of all the key points is generated; in the rescue navigation stage, a user determines a starting point and a destination, and the user is guided to reach the destination through a planning path guide arrow displayed on the holographic lens. By means of the intelligent helmet and the method, accurate positioning can be provided for the user in a building so that guidance can be provided when rescue is carried out in the building and rescue workers can quickly arrive at a rescue place, and the practical value is high.

Description

technical field [0001] The invention belongs to the field of fire-fighting and evacuation, and specifically proposes an intelligent helmet for rescue in buildings and a rescue navigation method thereof. Background technique [0002] The helmets used in traditional rescue have only protective functions and limited auxiliary functions. During building rescue, the structure of the building is complex and closed, the visibility is poor and it is not easy to reach the rescue site in time. In the prior art, the utility model patent "A Smart Rescue Helmet" (Patent No. 201621221926.4) introduces a rescue helmet with intelligent auxiliary functions. In this embodiment of the invention, the helmet is equipped with a high-definition camera, an infrared night vision lamp, a pyroelectric sensor, a body temperature sensor, a pulse sensor, an audible and visual alarm device, a GPS positioning device, and the like. The high-definition camera and infrared night vision light ensure normal n...
