Embodiment Construction
[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and through the examples. The following examples are to explain the present invention and the present invention is not limited to the following examples.
[0020] like figure 1 As shown, a method for constructing an indoor floor plan based on MT-PDR and light intensity information of the present invention comprises the following steps:
[0021] Step 1: Based on the crowdsourcing method, use the inertial sensor and light intensity sensor of the intelligent mobile terminal to realize the synchronous collection of data. The specific implementation process is as follows:
[0022] 1.1 Install the data acquisition software on the smart mobile terminal to realize the synchronous acquisition of the data of the three-axis acceleration sensor, the three-axis gyroscope sensor, the three-axis orientation sensor and the light intensity sensor;
[0023] 1.2 The user walks in...

The invention discloses an MT-PDR (Multi-Pedestrian Dead Reckoning) light intensity information-based indoor floor plan building method and provides an indoor floor plan building method for regional division on the basis of multi-pedestrian dead reckoning (MT-PDR) and light intensity information by facing an intelligent mobile terminal inertial sensor and a light intensity sensor, wherein course estimation is carried out by combining a four-sample equivalent rotation vector quarternion and a gyroscopic inflection point detection algorithm for the problem of heading-drift of the MT-PDR. Compared with a traditional method for building the indoor floor plan by combining the algorithms of 'indoor positioning and distance measurement' by adopting multiple wireless access nodes and sensor nodes, the MT-PDR light intensity information-based indoor floor plan building method has relatively low time complexity and algorithm complexity, and achieves the building of the indoor floor plan in a simple manner at low cost.
Description
technical field [0001] The invention relates to an indoor floor plan construction method based on MT-PDR and light intensity information. Background technique [0002] For indoor complex layout environments, such as shopping malls, parking lots, hospitals, etc., when people buy a commodity, find a parking space or a treatment department, they usually cannot quickly and accurately locate the destination and find the shortest path. , which will blindly search and consume a lot of time and energy. In order to solve the "last mile" problem of human beings, indoor navigation technology came into being. [0003] In recent years, indoor floor plan, an important supporting tool for indoor navigation, has gradually attracted people's attention and research. Among them, how to construct indoor floor plan is still an urgent problem to be solved. The traditional way of constructing indoor floor plans is mostly obtained by manual measurement or building plans provided by developers and...
