Inertial navigation system and method using digital holographic technology

Abstract

The invention discloses an inertial navigation system and method using a digital holographic technology. The system comprises a sensor module, a communication module and a digital holographic module;the sensor module is connected with the digital holographic module through the communication module; the sensor module comprises a first sensing unit, a second sensing unit, a third sensing unit, a fourth sensing unit, a fifth sensing unit, a sixth sensing unit, a seventh sensing unit, an eighth sensing unit and a ninth sensing unit, which are respectively worn on the left wrist, the right wrist,the left elbow, the right elbow, the left knee, the right knee, the left ankle, the right ankle and the middle of the waist of a user; the digital holographic module comprises a host and projection equipment; and the ninth sensing unit is connected with the host through the communication module. On the basis of the inertial navigation system, the disadvantage that indoor satellite signals of the traditional satellite positioning system are easily interfered can be overcome; relatively precise navigation data can be obtained without depending on external information; furthermore, the motion state of a wearer can be reflected in real time; and the inertial navigation system and method are suitable for a fire fighting scene complex in terrain and multiple in barrier.

Description

technical field [0001] The invention relates to the fields of inertial navigation and holographic projection, in particular to an inertial navigation system and method using digital holographic technology. Background technique [0002] The individual navigation system is suitable for firefighting, emergency rescue and disaster relief, especially in situations where rescue operations are difficult to carry out after an indoor fire. There is a need for a single-soldier navigation system that can provide high-level safety guarantees for firefighters in emergencies such as emergency rescue and target tracking. [0003] Traditional satellite positioning systems, due to the influence of indoor wall obstacles, satellite signals are extremely susceptible to interference, so satellite positioning systems cannot accurately obtain the reliable location of firefighters. Later, people developed the inertial navigation system. Since the inertial navigation system does not depend on exter...
