Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] Such as figure 1 As shown, a method for sorting spatial positions based on intelligent terminals provided by the present invention includes the following steps:
[0023] Step 101, start the master control node to collect the absolute position range information of all terminals participating in the sorting based on GPS or network positioning, such as image 3 As shown, it is the absolute position range information of each terminal participating in the sorting before sorting. It can be seen that the absolute position range information of terminals 2, 5, 7, 8, and 9 overlaps, and the absolute position range information of terminals 2, 7, and 9 has Overlapping, the absolute position range information of terminals 2, 7, 8, 10, and 12 overlaps, and the absolute position range information of terminals 1, 6, 8, and 11 overlaps;
[0024] Step...

The invention discloses an intelligent terminal-based spatial position sorting method. The intelligent terminal-based spatial position sorting method comprises the following steps that: a main control node collects absolute position range information of all participating nodes; each participating node generates a unique piece of anchor point information; each participating node shoots the anchor point information of surrounding adjacent nodes through a camera, analyzes the data information in the anchor point information through an image identification system, calculates the relative position information to adjacent nodes, and transmits the relative position information to the main control node; the main control node collects the relative position information of each participating node, iteratively calculates the relative position of each participating node in the overall node group according to real-time data, sorts and anchors according to the relative positions, performs error correction on the absolute position range information of each participating node, and feeds the corrected absolute position range information back to the corresponding participating node. According to the intelligent terminal-based spatial position sorting method, the position of a single intelligent terminal can be distinguished in a position superposition scene, the positioning error of each intelligent terminal can be corrected, and the absolute position range of each intelligent terminal can be reduced, so that the positioning information is more accurate.
Description
technical field [0001] The present invention relates to the field of intelligent terminals, in particular to a method for sorting spatial positions based on intelligent terminals. Background technique [0002] The smart terminal refers to the current Andorid, WindowsPhone, iOS and other mobile phones, tablets or electronic devices with basic positioning functions. [0003] At present, most of the positioning accuracy of civilian smart terminals is in an area of about 15 to 20 meters. However, in densely populated places, the locations of the crowd are mostly superimposed, and it is difficult to analyze the location of the smart terminals held in such a crowd, and it is usually impossible to distinguish a single smart terminal. Contents of the invention [0004] The technical problem to be solved by the present invention is to estimate the relative relationship between the positions of each device in the position superposition scene, and to distinguish a single intellige...
