A Method for Indoor Spatial Positioning

Abstract

The invention relates to the technical field of communication, and concretely discloses indoor space positioning equipment and a positioning method thereof. The positioning equipment comprises an electromagnetic induction sensor, a central processor, an accelerometer, an angular velocity meter, a barometer and a GPS navigation apparatus; the electromagnetic induction sensor, the central processor, the accelerometer, the angular velocity meter, the barometer and the GPS navigation apparatus are arranged in the indoor space positioning equipment, and the electromagnetic induction sensor, the accelerometer, the angular velocity meter, the barometer and the GPS navigation apparatus are connected to the central processor. According to the invention, accelerated speed is taken as a base, electromagnetic induction, height and angular velocity technology are combined, movement locus of three-dimensional space can be reflected, and a purpose of omni-directional stereo positioning can be reached for indoor space positioning. In the invention, the collected multiple groups of data can be combined for being processed, the date can be complemented each other, so that measure precision for positioning can be increased. The equipment has the advantages of small volume, light weight and easy carrying.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an automatic testing and positioning method for indoor wireless signals in the mobile communication industry. Background technique [0002] In the prior art, the indoor space positioning methods include GPS positioning, pedometer positioning and electronic compass positioning. [0003] The existing indoor space positioning methods have the following problems: [0004] Traditional GPS positioning is greatly limited in indoor applications. GPS positioning has many problems such as insufficient indoor signal strength or no signal, signal interference, and signal blockage, which lead to low positioning accuracy and are difficult to apply in indoor spaces. [0005] The pedometer can accurately reflect the number of steps taken by the pedestrian, but the pedometer reflects the linear one-dimensional movement, and cannot perform all-round three-dimensional positioning of the indo...

AI Technical Summary

Problems solved by technology

[0004] Traditional GPS positioning is greatly limited in indoor applications. GPS positioning has many problems such as insufficient indoor signal strength or no signal, as well as signal interference and signal blockage, resulting in low positioning accuracy and difficult to apply in indoor spaces.

[0005] The pedometer can accurately reflect the number of steps taken by the walker, but the pedometer reflects the linear one-dimensional movement, and cannot perform all-round three-dimensional positioning of the indoor space.

[0006] The electronic compass is easily disturbed by the magnetic field environment, and often cannot reflect the real direction

[0007] At present, the existing indoor positioning is almost all based on inertial equipment, there is a large cumulative error, the indoor space positioning accuracy is low, the positioning is not accurate, and there are still problems that cannot adapt to various application environments

There is no effective solution so far
