Abstract

The invention discloses a positioning precision prediction method and device, and a signal source layout determination method and device. The positioning precision prediction method comprises the following steps: determining a signal source layout scheme in a target area; according to the signal source layout scheme and a signal propagation model, analog signal acquisition information corresponding to at least one sampling point in the target area is determined; according to the analog signal acquisition information and a signal positioning algorithm, analog positioning information of the sampling point is determined; and according to the simulated positioning information and the actual position information of the at least one sampling point in the target area, determining the predicted positioning precision corresponding to the target area. Therefore, the positioning effect corresponding to the signal source layout scheme can be determined in a simulation mode, data reference is provided for subsequent selection of the signal source layout scheme or adjustment of the signal source layout scheme, and the final area positioning effect can be improved.

Description

technical field [0001] The present invention relates to the technical field of positioning algorithms, and in particular, to a positioning accuracy prediction method, device, and signal source layout determination method and device. Background technique [0002] The ability to locate the geographic location of mobile terminals and IoT devices is the technical basis for navigation and location-based services (LBS) applications. Various location-related services, such as emergency security, intelligent warehousing, crowd monitoring, precision marketing, mobile health, virtual reality, and human socialization, all depend on the positioning capabilities of mobile terminals and IoT devices. The traditional positioning function mainly relies on the satellite positioning system to complete, but for the indoor environment or the outdoor environment with many obstacles and complex terrain, the traditional satellite positioning technology is difficult to meet the existing various posi...
