Embodiment approach 1

[0040] Implementation Mode 1 (Scene in an open and unobstructed area).

[0041] The process of implementation mode 1 (such as figure 1 ) includes the following steps:

[0042] Step S10, firstly, use software to construct a partial map to obtain all geographical information of the mobile area required by the smart mobile device, and obtain the location of the mobile smart device in the required mobile area through wireless local area network positioning technology or satellite positioning, geomagnetic positioning and other technologies. The geographical location information of the range, upload these geographical information and the location information of the mobile smart device to the corresponding APP of the smart mobile device (smart phone, tablet computer, etc.), and then move the mobile phone on the obtained regional map. The position of the smart device is used as the starting point to draw the moving path, and then the APP will collect the drawing path information in t...

Embodiment approach 2

[0058] Implementation mode 2 (actual complex comprehensive scenario).

[0059] The process of the second embodiment (such as Figure 5 ) includes the following steps:

[0060] Step S10, firstly, use software to construct a partial map to obtain all geographical information of the mobile area required by the smart mobile device, and obtain the location of the mobile smart device in the required mobile area through wireless local area network positioning technology or satellite positioning, geomagnetic positioning and other technologies. The geographic location information of the range, upload these geographic information and the location information of the smart device being moved to the corresponding APP of the handheld communicable smart device (smart phone, tablet computer, etc.), and then on the obtained regional map, Draw the moving path starting from the position of the smart device being moved, and then the APP will collect the drawing information in the following steps...

Abstract

The invention relates to an indoor path planning and navigation method of a mobile intelligent device and belongs to the wireless control robot navigation technical field. The indoor path planning and navigation method includes the following steps that: step 1, an indoor path planning and navigation application installed in a handheld communicable intelligent device automatically obtains an indoor path planning and navigation map, and then a user draws a path in the indoor path planning and navigation map of the APP (application), the APP acquires drawn path information of the user; step 2, the APP carries out path coordinate information conversion on the drawn path information; step 3, drawn path-to-actual geographic information coordinate conversion is carried out; step 4, the APP assess the rationality of the actual situation of the drawn path; and step 5, the APP transmits reasonable path data to the mobile intelligent device. With the method adopted, autonomous path planning and autonomous navigation have relatively better timeliness and high conciseness, and can be customized.

Description

technical field [0001] The invention relates to an indoor path planning and navigation method of a mobile intelligent device, which belongs to the technical field of wireless control robot navigation. Background technique [0002] At present, the relatively mature navigation technology of mobile smart devices mainly uses the help of GPS positioning system to realize navigation, especially for outdoor navigation, GPS is widely used. However, indoors, due to technical limitations, the accurate positioning of GPS is affected by many factors, so most indoor navigation does not use GPS positioning to achieve navigation. At present, the relatively widely used indoor navigation methods mainly include: electromagnetic navigation, visual navigation (the method of taking images by the lens, etc.). Electromagnetic navigation is relatively expensive and difficult to implement; relatively speaking, visual navigation is easier to implement, but it is not accurate enough, which leads to m...
