Problems solved by technology
[0002] At present, when users use handheld terminals, some indoor places are very large and the regional distribution is relatively complicated. After users enter such places, it is difficult to find the target area or location
Although there are currently some solutions that use handheld terminals for navigation in indoor places, these solutions have high requirements for software and hardware in these places. At the same time, these solutions cannot quickly and accurately calculate the real-time position of the handheld terminal, which makes Navigation accuracy is low

Embodiment Construction
[0060] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0061] The invention provides an indoor navigation method for a handheld terminal.
[0062] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the indoor navigation method for the handheld terminal of the present invention.
[0063] In the first embodiment, the indoor navigation method of the handheld terminal includes:
[0064] Step S10, after receiving the indoor navigation instruction issued by the user, the handheld terminal controls its camera to acquire images within the lens range, and performs data analysis on the barcodes of the barcode labels preset at indoor preset positions in the images within the lens range, Obtain the identification information of each barcode label in the image within the lens range, and select a preset number of color blocks from at least two barcod...

This application discloses an indoor navigation method of a handheld terminal, including: after receiving an indoor navigation instruction, controlling a camera to obtain an image within a scope of a lens, performing analysis on a barcode of a barcode label in the image, obtaining identifier information of each barcode label, and selecting color blocks from at least two barcode labels according to a color block selection rule; calculating coordinates corresponding to each of the color blocks in a pixel coordinate system according to a position of each selected color block in the image within the scope of the lens; and calculating coordinates corresponding to each of the color blocks in a world coordinate system on the basis of association data of identifier information of the barcode labels and coordinates of the color blocks in the world coordinate system according to a barcode label at which each selected color block is located, and calculating coordinates of the handheld terminal in the world coordinate system according to a coordinate calculation rule. The present invention further discloses a handheld terminal for indoor navigation and a storage medium. This application can quickly and accurately calculate a precise real-time position of the handheld terminal, thereby improving indoor navigation precision.
Description
technical field [0001] The present invention relates to the technical field of navigation, in particular to an indoor navigation method for a handheld terminal and the handheld terminal. Background technique [0002] At present, when a user uses a handheld terminal, some indoor places are very large and the area distribution is relatively complicated. After entering such a place, it is difficult for the user to find the target area or location. Although there are currently some solutions that use handheld terminals for navigation in indoor places, these solutions have high requirements for software and hardware in these places. At the same time, these solutions cannot quickly and accurately calculate the real-time position of the handheld terminal, which makes Navigation accuracy is low. Contents of the invention [0003] The main purpose of the present invention is to provide an indoor navigation method of a handheld terminal and the handheld terminal, aiming at realizin...
