Problems solved by technology

However, most of the above technologies have two disadvantages: first, it needs to lay special equipment for positioning; second, it needs to invest manpower and material resources in the later stage for maintenance
However, because the indoor positioning environment is more complex and changeable than the outdoor positioning environment, when people enter the room from the

Embodiment Construction

[0046] Such asfigure 1 As shown, the flow process of the indoor and outdoor integrated positioning method based on electromyographic data provided by the present invention is described in detail as follows:

[0047] Step S1, collect the myoelectric signals of the experimenter in different motion modes through the myoelectric sensor placed on the lower limbs of the human body; make the experimenter move within the range of a specific movement path, and collect different movements through several myoelectric sensors placed on the lower limbs of the human body EMG signals in the mode. In this process, the experimenter’s test path of the movement mode includes both the outdoor path and the indoor path. The lower limb muscles selected in the experiment include the vastus lateralis, rectus femoris, lateral head of the gastrocnemius muscle, and medial head of the gastrocnemius muscle. An EMG Sensors, a total of 8 myoelectric sensors on the left and right lower limbs, and the myoelect...

Abstract

The invention is applicable to the field of improvement of positioning technology, and provides an indoor and outdoor integrated positioning method based on electromyographic data. The method comprises the steps of enabling an experimenter to move in a specific motion path range, acquiring electromyographic signals through an electromyography sensor, and calculating number of walking steps; according to the data of the electromyography graph, performing processing of the electromyographic signals through a series of signal processing methods, calculating the number of walking steps, and classifying the different motion states; establishing an empirical model for different motion gaits obtained by classification, and calculating the step size in each motion state; and on the other hand, obtaining the gait data through integration of the motion starting point provided by a GPS and the electromyographic signal, and obtaining the orientation data through an electronic compass, so that thecorresponding points of pedestrian positions in the indoor environment, from the outdoor to the indoor, and in the indoor environment. Based on the electromyographic information, simple calculation iscarried out, so that the positioning accuracy is effectively improved.

Description

technical field [0001] The invention belongs to the field of positioning technology improvement, and in particular relates to an indoor and outdoor integrated positioning method and system based on electromyographic data. Background technique [0002] Today, the Global Navigation and Positioning System (GNSS) can provide people with high-precision outdoor positioning services, and location-based services have become a standard function of today's smart mobile devices. However, due to the blocking of satellite signals by buildings, GNSS cannot be used indoors and provide the same high-precision indoor positioning services. At the same time, with the development of mobile location information services, people's demand for navigation applications has gradually changed from outdoor navigation to seamless indoor and outdoor integrated navigation. Therefore, indoor positioning and navigation urgently need to be expanded and deepened. [0003] In order to provide continuous navig...
