Document Type and Number:
WIPO Patent Application WO/2019/126950
Kind Code:
A1
Abstract:
A positioning method, a cloud server, a terminal, a system, an electronic device and a computer program product, relating to the field of positioning navigation. The method comprises: acquiring positional information concerning a preset point in a first acquisition manner; acquiring in real time positional information concerning a moving target in a second acquisition manner; determining whether the moving target enters a key area centered on the preset point, acquiring in real time positional information concerning the moving target in a third acquisition manner when the moving target enters the key area. The invention configures a key area by means of a preset point, locates a moving target in a lower-accuracy positioning manner when the moving target is outside the key area, and switches to a higher-accuracy positioning manner when the moving target enters the key area, thereby reducing the amount of data transmission and the amount of computation whilst achieving high-accuracy positioning, and also saving costs to a great extent.
