Embodiment Construction

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0056] A plurality of visible light sources can be arranged on the top surface of the room, and positioning marks are arranged in the visible light sources. The visible light source emits the positioning mark through the light while providing illumination light, and the positioning terminal in the room receives the positioning marks emitted by a plurality of the visible light sources, and performs indoor positioning through each positioning mark . However, it is necessary to ration...

Abstract

The invention discloses an indoor layout method and device of a visible light source. According to the top surface of an indoor space, a first layout area is produced first, and a second layout area can be determined in the first layout area. When the second layout area is provided with the visible light source, the minimum value of the illumination intensity received from a light source receiver meets the preset illumination intensity range, so that a target layout area can be determined in the second layout area. When the target layout area area is provided with the visible light source, the maximum value of the position error of the light source receiver meets the preset position error range, thus, the target layout area can meet both the illumination and position requirement, so that illumination and position effects are achieved at the same time if the visible light source is arranged in the target layout area.

Description

technical field [0001] The present application relates to the technical field of wireless positioning, in particular to an indoor layout method and device for visible light sources. Background technique [0002] At present, the demand for positioning and navigation system applications is increasing day by day. The wireless positioning technology represented by the GPS satellite positioning and navigation system in the United States is very mature and has been widely used in various fields. However, the positioning and navigation system is mainly used outdoors. Due to the blocking of radio signals by more and more buildings in modern times, the positioning and navigation system cannot be well applied to indoor scenes. [0003] In an indoor environment, there are often multiple visible light sources for lighting. Based on visible light communication technology, a positioning mark can be set in the visible light source, and the positioning mark can be emitted through the radiat...
