Abstract

The invention discloses a multi-sensor fusion life detection positioning system and positioning method. The system comprises a radar detection unit for providing real-time detection data for the computation of a three-dimensional positioning coordinate of a life entity under the ruins, and sending the real-time detection data to a data transmission unit; a micro-vibration detection unit for detecting a vibration signal; an audio-video detection unit for providing image and acoustic wave real-time detection data for the life entity under the ruins, checking the actual environment, the life entity location and physical sign information under the ruins, and providing more accurate rescue information through real-time conservation; the data transmission unit for receiving the detection data sent out by the radar detection unit, the micro-vibration detection unit and the audio-video detection unit and forwarding the same; and a detection display terminal for dynamically displaying the detection process and the detection result in real time. The method is implemented based on the above system. The system disclosed by the invention has the advantage of being simple in operation, wide in applicable range, and capable of greatly improving the life detection positioning precision.

Description

technical field

[0001] The invention mainly relates to the technical field of life detection, in particular to a multi-sensing fusion life detection positioning system and a positioning method. Background technique

[0002] The current domestic earthquake rescue life detection equipment is mainly two-dimensional radar life detector, audio and video detector and vibration audio life detector. Accurate rescue requirements.

[0003] The radar life detection and positioning system based on the principle of the Doppler effect can penetrate several meters or even tens of meters of stone or concrete obstacles to detect and locate survivors under the ruins. However, in actual operation, this method of relying only on radar detection has the following problems:

[0004] Radar life detection and positioning is to determine whether there is life and its orientation under the ruins after algorithmic analysis and processing of the reflected electromagnetic waves. However, due to the c...
